更新済み

Your new PC is ready, but all your files are still trapped in the old one. USB‑C won't talk to USB‑A, 1TB of data won't fit on a dusty 16GB flash drive, and that transfer cable you bought ships with a driver CD—but new PC doesn't even have a disc drive. These aren't one‑off headaches; they're the exact scenarios real users describe when they search for how to transfer files from PC to PC:

  1. "I have a PC with a Type C port and another PC with a Type A port.
    When I connect these, I am unable to transfer files."

  2. "My new computer does not have a CD-ROM drive. How do I install the driver?"

  3. "How do I get everything on my old PC on my new PC?"

Six methods exist. One of them is wireless, free to start, and completely independent of whether your computers run Windows, macOS, or other USB languages. Let's find yours!

1. DeskIn — Best for Wireless, Cross-Platform, Cable‑Free Transfer

Advantages with DeskIn

  • No cables, no adapters, no driver CDs – works entirely over Wi-Fi

  • Compatible with both Windows and macOS – easy cross-platform transfer

  • No file size limits – send 100GB+ videos or backups without splitting

  • Direct peer-to-peer transfer – files never touch a third-party cloud server

  • Drag-and-drop simplicity – no network discovery or drive mapping required

  • AES-256 encryption – your files are secure

  • Free tier available – no credit card required to start

Disadvantage

  • Requires both PCs to be on the internet

Mismatched ports and missing drivers are the most common reasons PC-to-PC transfers fail. DeskIn removes both problems. No cable. No adapter. No installation media required. The application establishes a direct, encrypted peer-to-peer connection over Wi-Fi. It works on both Windows and macOS, and port types don’t matter.

DeskIn bypasses the physical layer entirely: No dongles, no "driver not found" errors, no expensive docks. This is also the only consumer‑friendly tool on this list that lets you transfer files between Windows and Mac wirelessly without any technical setup. Your old Windows workhorse and your new MacBook Air? They shake hands instantly.

How to transfer files with DeskIn

Step 1. Download DeskIn

download DeskIn to transfer file for PC

Visit DeskIn Personal Download and install it on both devices. Create and log in to your account on both devices. DeskIn offers a free trial, and you can start using it immediately.

Free download DeskIn

Step 2. Choose Remote PC to Connect

Navigate to the Device List, find the target PC, click the File Transfer button, and enter the Password (Remote Control).

Note: If your two devices are not logged into the same account, you will also need to enter the device code.

Step 3. Send Files Instantly

Simply drag and drop files between your computers. DeskIn will transfer files at 12MB/s. At the bottom of the page, you can track the progress of the file transfer. After a successful transfer, you can see the transferred files in your folder.

Note: DeskIn supports cross-system file transfers of unlimited size, type, and number.

That's it. Your files move directly - no cloud staging, no size limits on the free tier for transfers, and no waiting for uploads to finish before downloads can start.

2. External Hard Drive: Best for Massive Offline Transfers (1 TB+)

Advantages

  • No internet required; works anywhere

  • One‑time hardware cost; no subscriptions

  • Total physical control: Are files directly on my computer at all times

Disadvantages

  • A physical device can be lost, stolen, or dropped

  • No built‑in encryption; data is exposed if the drive is misplaced

  • You must own a drive large enough to hold all your data

The Reddit user facing a terabyte of data wasn't exaggerating: "I want to transfer about 1TB of data. It's mostly just in a few folders." When you're moving that much information, cloud uploads can take days. External drives are still the fastest option for moving large amounts of data.

How to transfer files with an external hard drive

  1. Connect the external hard drive to your old PC

  2. Open your file explorer and drag the files or folders you want to transfer into the drive

  3. Safely eject the hard drive and connect it to your new PC

  4. Open the drive in your File Explorer and move the files to their new location

Pro tip: If you are moving your files directly to Windows system folders (like the entire C:\Users directory), you may need administrator permissions. Copy what you can; use DeskIn for the rest.

3. USB Transfer Cable: Best for Direct Wired Transfer Without a Network

Advantages

  • Faster than external HDDs for thousands of small files

  • No router or Wi‑Fi needed

  • Often includes simple transfer software

Disadvantages

  • Requires a specialized USB cable transfer files — not a standard USB cord

  • PCs must be within cable length (usually 1–2 meters)

  • Driver CDs are often included; new PCs may lack optical drives

  • Cable becomes e‑waste after one use

The Reddit user who asked about bridging cables hit the exact pain point: "I've read about USB bridging cables, but you seem to need to install software from a CD. My new computer does not have a CD-ROM drive." This method works—if you can solve the driver dependency before your old PC is packed away.

How to transfer files with the USB Transfer Cable

  1. Connect the cable to both PCs using the appropriate USB ports

  2. Launch the software that came with the cable (usually auto-installs)

  3. Select the files or folders you want to transfer and begin the process

Can you use an HDMI cable?

No. This question appears in forums constantly. HDMI carries video and audio. It does not carry your documents.

4. Local Network (Wi‑Fi / LAN) — Best for Frequent Transfers on the Same Router

Advantages

  • No new hardware to buy

  • Good for ongoing, recurring transfers

  • Works wirelessly; no cables between PCs

Disadvantages

  • Speed is capped by your router and Wi‑Fi congestion

  • Both PCs must be powered on and on the same network

  • Initial setup requires navigating Windows Settings

If you frequently ask how to move downloads from one laptop to another in the same household, network sharing is the easiest ongoing option. Once set up, it works like moving files between folders on one computer — no speed limits, no USB sticks.

How to set up network sharing (Windows 10/11)

  1. Connect both PCs to the same Wi‑Fi or wired network.

  2. On the source PC, open Settings > Network & Internet > Ethernet (or Wi‑Fi) and ensure the network profile is set to Private.

  3. Go to Control Panel > Network and Sharing Center > Advanced sharing settings.

  4. Turn on Network discovery and File and printer sharing.

  5. Right‑click the folder you want to share → Properties → Sharing → Share.

  6. On the destination PC, open File Explorer, click Network in the sidebar, and double‑click the source PC's name.

For remote workers: You can also transfer files over remote desktop by connecting to the office PC and mapping local drives in the Remote Desktop session—ideal for pulling specific files while travelling.

Cloud Storage — Best for Ongoing Sync and Always‑Available Access

Advantages

  • Files are encrypted in transit and at rest

  • Accessible from any device, anywhere

  • No physical media to lose or damage

Disadvantages

  • Requires a paid subscription for large volumes

  • Upload then = double the time

  • Speed is entirely dependent on your internet pipe

Not everyone is doing a one-time migration. Some users want their files to live in the cloud permanently—available on their phone, tablet, and laptop simultaneously. Cloud storage is less a "transfer method" and more a permanent relocation.

How to transfer files with Cloud Storage

  1. Install your preferred cloud provider's desktop app (Google Drive, OneDrive, Dropbox) on the old PC.

  2. Sign in. Choose which folders to sync to the cloud.

  3. Wait for the upload to complete. (For 1TB of data on average U.S. broadband, plan for roughly 48 hours of uninterrupted upload.)

  4. On the new PC, install the same app and sign in with the same account.

  5. The files will sync down to the new machine.

Heads up: If you delete a synced file on one device while both are signed in, it will be deleted everywhere. Always sign out of your old PC before wiping it.

6. PC Migration Software: Best for Full System State Migration

Advantages

  • Transfers applications, settings, and user profiles — not just files

  • High security (SFTP, AES‑256) for regulated industries

  • Can schedule transfers during off‑peak hours

Disadvantages

  • Expensive (often enterprise licensing)

  • Steep learning curve

  • Massive overkill for most home users

The Reddit user asking "How do I get everything on my old PC on my new PC?" might not realize that "everything" includes application configurations, saved login sessions, and system tweaks accumulated over the years. Regular tools move your files. Migration software moves everything, including your apps, settings, and saved sessions.

How to transfer files with PC Migration Software (varies by vendor)

  1. Install the migration software on both PCs.

  2. Choose a transfer type: network, direct cable, or external media.

  3. Select which system elements to migrate (files, apps, settings).

  4. Follow the vendor's wizard to complete the transfer.

When you actually need this: If you are moving your files directly on Windows system folders that Windows locks during normal operation, or if you are migrating an entire domain‑joined corporate machine, consumer tools won't cut it. This is a job for IT.

FAQs on Transferring Files (PC to PC)

1. How do I transfer everything from my old computer to my new computer Windows 10 to Windows 11?

For personal files: Use DeskIn for a fast, wireless transfer—it's free for up to 2 GB and inexpensive for larger volumes. Unlike a bridging cable, you don't need to hunt down drivers or worry about whether your new PC has a CD-ROM drive.

For system settings: Use the built‑in Windows Backup app (Settings > Accounts > Windows Backup) to sync your preferences to your Microsoft account. Restore them during Windows 11 setup.

2. What is the easiest way to transfer files from PC to PC wirelessly?

DeskIn requires zero configuration beyond installing and logging in to the app. Both PCs discover each other automatically: no network sharing settings to toggle, no folder permissions to configure. If you prefer native tools, Windows Nearby Sharing works when both devices are on the same Wi‑Fi, but it can be finicky with large folders. DeskIn handles bulk transfers more reliably.

3. How do I transfer files if my PCs have different USB port types?

This is the exact situation DeskIn was built for. The Reddit user with "a PC with a Type C port and another PC with a Type A port" doesn't need an adapter, a dongle, or a special cable. Use a wireless method. DeskIn or local network sharing means port types don’t matter at all. Your files move over Wi-Fi instead.

4. Should I wipe my old computer after transferring files?

Yes, absolutely — if you plan to sell, recycle, or give it away. Deleting files and emptying the Recycle Bin is not enough. On Windows 10 or 11: go to Settings > System > Recovery, click Reset this PC, and select Remove everything. This ensures your personal data is unrecoverable. Before you wipe it, double-check that DeskIn (or your chosen transfer method) successfully moved everything. Once you reset, there's no going back.

Pick the Right Method for Your Transfer

No single method works for everyone — only the right one for your situation. External drives are fastest for large data. Windows Sharing works well at home. Migration software is for IT pros. But if you're dealing with mismatched ports, missing CD-ROM drives, or transferring between Windows and Mac, DeskIn is the only tool that skips all those problems. No cables, no drivers, no frustration. DeskIn also works for ongoing remote access, not just one-time transfers.

How to Set Up & Use Chrome Remote Desktop: Complete Beginner's Guide | DeskIn Japan

How to Set Up and Use Chrome Remote Desktop in Japan: A Complete Beginner's Guide to CRD

What You'll Learn in This Article

This article walks through the basic setup and features of Chrome Remote Desktop (CRD), Google's free remote access tool — explained clearly for first-time users.

CRD is free, simple to configure, and integrates smoothly with your existing Google account and Chrome browser. It works across Windows, Mac, and smartphones, making it easy to get started with remote access from virtually any device.

For everyday personal use and one-off remote support sessions, it's an excellent option — though its features are limited to "Remote Access" and "Remote Support." For more advanced requirements — 4K display quality, low latency, or stable connections inside Japanese corporate networks — a professional-grade tool like DeskIn is worth considering.


Introduction

What Is Chrome Remote Desktop?

Chrome Remote Desktop (CRD) is a free remote access tool developed by Google. All you need is the Chrome browser and a Google account to remotely control another PC over the internet, from anywhere. No additional hardware is required, making it one of the most accessible ways to get started with remote desktop access.

Why Remote Desktop Is Useful in Japan

Hybrid work has become a fixture across Japan's working culture. Many companies — especially in Tokyo and other major cities — now expect employees to split their time between the office and home. Students, too, often find themselves needing access to files or software left behind on a home PC. And for those who have just joined the workforce as shinshakajin (新社会人 — literally "new members of society," the term for fresh graduates entering their first job, typically in April when Japan's fiscal and academic year begins), juggling unfamiliar tools across multiple environments can be genuinely stressful. Chrome Remote Desktop offers a practical, low-barrier solution for all of these situations.

Which One Is Better, Chrome Remote Desktop Or Microsoft Remote Desktop?

Chrome Remote Desktop's Two Core Features

  1. Remote Access — Connect to Your Own Devices, Anytime

The "Remote Access" feature lets you connect to your home or office PC from any location, at any time. Once the host machine is configured, you can control it remotely as long as it's powered on — even if no one is sitting in front of it. This is ideal for pulling up a file you left on your home PC while you're at school or the office, or for using your full desktop environment from a laptop while you're out.

  1. Remote Support — Temporary Screen Sharing for Troubleshooting

The "Remote Support" feature is built for one-off, temporary sessions. By sharing a connection code, you can let someone else view or control your screen — or do the same for them — without exchanging account credentials. It's a clean and simple way to help a classmate, colleague, or family member work through a technical issue remotely.

Chrome Remote Desktop is designed specifically around these two functions. That focused scope makes it particularly easy to pick up, even if you've never used a remote desktop tool before.

Chrome Remote Desktop feature switching

What You'll Need Before Getting Started

A Google Account

A Google account is required. If you don't already have one, register before you begin. If you're already using Gmail or Google Drive, that same account will work here.

Google Chrome Browser

CRD runs inside the Chrome browser, so Chrome needs to be installed on both the host (the PC you want to access remotely) and the client (the device you're connecting from). Chrome can be installed alongside any other browser without conflict.

A Stable Internet Connection

Remote desktop transmits live screen data over the internet, so a reliable connection on both ends matters. If your Wi-Fi is inconsistent, a wired connection will generally produce a much smoother experience.

Step-by-Step Setup Guide

Setting Up the Host PC (the Computer You Want to Control)

Start by configuring Chrome Remote Desktop on the machine you'll be accessing remotely.

  1. Open Google Chrome and navigate to the Chrome Remote Desktop page.

  2. Follow the on-screen prompts to add the extension and complete the installation.

Chrome Remote Desktop addition and installation procedure
  1. Enable "Remote Access" and follow the steps to set a PIN code of at least six digits.

  2. Once setup is complete, this PC will appear in your list of remotely accessible devices.

Connecting from the Client Device (the Device You're Using to Connect)

Next, prepare the device you'll be connecting from.

  1. Log into Chrome with the same Google account and open the Chrome Remote Desktop page.

  2. Select the host PC from your device list.

Chrome Remote Desktop device connection screen
  1. If connecting from a smartphone or tablet, download the dedicated iOS or Android app and select your target PC from within the app.

Authenticating with Your PIN Code

After selecting the host PC, you'll be prompted to enter your PIN to verify the connection.

  1. Enter the PIN you created during setup on the client device.

  2. Once authenticated, the host PC's screen will appear on your device and you'll be able to control it with your mouse and keyboard.

  3. The connection is encrypted and can be ended at any time.

Tips for Getting More Out of CRD

Make the Most of Keyboard Shortcuts

Using keyboard shortcuts deliberately can make a real difference to your efficiency in a remote session. This is especially worth thinking about if you're switching between Windows and Mac, where key behaviour differs — particularly around:

  • The difference between the Ctrl and Cmd keys

  • Full-screen toggling and window switching

Familiarising yourself with these basics in advance will help things feel more natural. If shortcuts are being captured by your local device instead of reaching the remote machine, check the settings for an option like "Send all keyboard input to remote" — this is usually the fix.

Using CRD on Mobile: What to Expect

The mobile experience differs quite a bit from working on a desktop. Chrome Remote Desktop's mobile app is built around touch controls:

  • Swipe to move the mouse cursor

  • Pinch to zoom in or out

  • Toolbar at the bottom of the screen to access the keyboard and menu

Precise input — longer text entry, drag-and-drop, clicking small targets — is slower and more effortful on mobile than on a PC. In practice, mobile access works best for quick checks and light tasks. For anything more involved, a laptop or desktop will serve you much better.

The Limitations of Chrome Remote Desktop

Simplicity Has Its Ceiling

Chrome Remote Desktop is, at its core, a tool built for "Remote Access" and "Remote Support" — nothing more. That focus is part of what makes it easy to use, but it also means that more specialised requirements hit a wall fast. If you need to transfer large files quickly, manage multiple users or devices, or keep detailed logs of remote sessions, you'll find CRD doesn't have the tools for the job.

Many Japanese companies — particularly larger organisations — maintain strict internal network environments managed by their IT departments (joho shisutemu-bu, 情報システム部). Firewalls, proxy settings, and restrictions on Google services are common, particularly in finance, manufacturing, and government-adjacent industries. In these environments, Chrome Remote Desktop connections can become unreliable, suffer significant lag, or fail entirely.

If you've started a new job in Japan and found that CRD simply won't connect from the office network, this is almost certainly why.

Dependency on Your Google Account

Because CRD is tied to a Google account, any disruption to that account — a forgotten password, an account lock, or a multi-factor authentication hiccup — directly affects your ability to access remote machines. For personal use this is manageable, but for anything business-critical, it's a meaningful single point of failure.

Windows HomeエディションのRDP制限とDeskInによる解決策

Windows Homeでリモートデスクトップが使えない理由と解決策【Proアップグレード不要】| DeskIn

この記事でわかること

  • Windows Homeエディションでリモートデスクトップのホストになれない理由

  • 「リモートデスクトップ 接続できない」エラーの正体

  • ¥28,380のProアップグレードなしで今すぐ使える方法

  • AnyDesk・TeamViewer・DeskInの無料プラン比較

はじめに:あなただけじゃない、この「壁」にはまった人は全国にいます

Yahoo!知恵袋や価格.comの掲示板を見ていると、こんな書き込みをよく見かけます。

「新しいノートパソコンを買って、自宅のPCにリモートデスクトップで接続しようとしたら『リモート デスクトップはリモート コンピューターに接続できませんでした』と表示されてしまいます。設定がおかしいのでしょうか?」

「Windows 11 Homeを使っています。会社のPCから自宅のPCに繋ごうとしてもエラーになります。何度試しても繋がりません。」

実は、これは設定の間違いでも、パソコンの故障でもありません。Windows Homeエディションには、リモートデスクトップで「接続を受け入れる」機能がそもそも入っていないのです。

ヨドバシカメラやビックカメラ、Amazon.co.jpで買える一般的なノートパソコンやデスクトップPCのほとんどは、このHomeエディションです。つまり、知らないうちに「リモートデスクトップで繋がれない」PCを買っていた、というケースが非常に多く起きています。

この記事では、その理由と、Proへのアップグレードなしで解決できる方法をわかりやすくお伝えします。

そもそも「Windows HomeとPro」は何が違うのか

Windowsには大きく分けて「Home」と「Pro」の2種類があります。

コンシューマー(一般消費者)向けに販売されているPCの大半にはHomeエディションが入っています。ProはBusinessユーザー向けのエディションで、HomeにはないビジネストしてのITの機能がいくつか追加されています。そのうちのひとつが、リモートデスクトップのホスト機能です。

「ホスト」と「クライアント」の違い

リモートデスクトップには2つの役割があります。

  • クライアント(接続する側): 手元のデバイスから、別のPCを操作する側

  • ホスト(接続される側): 遠隔から操作「される」PC

Microsoftは意図的に、ホストになる機能をHomeエディションから除外しています。つまり、Homeエディションのパソコンは「外から繋ぎに行く」ことはできても、「外から繋いでもらう」ことができないのです。

これが、「繋がらない」「接続できない」エラーの正体です。エラーメッセージには理由が書かれていないので、設定を何度直しても解決しません。

H3: なぜ日本でこの問題が多いのか

3つの理由が重なっています。

① ヨドバシ・ビックカメラ・Amazonで売っているPCの大半はHomeエディション
コストを抑えるため、一般向けに販売されるPCにはHomeが標準搭載されています。パッケージや仕様表にも小さく書いてあるだけで、「リモートデスクトップは使えません」と目立つところに書かれているわけではありません。

② 中小企業でもHomeが混在している
業務用のパソコンとしてHomeを採用している会社も少なくありません。テレワークを始めようとした際に、初めてこの制限に気づくケースがあります。

③ 購入時点では気づきにくい
「リモートデスクトップを使いたい」と思って購入したわけでなくても、後から必要になることはよくあります。その時点で初めて壁にぶつかります。

公式の解決策は「Proにアップグレード」:でも¥28,380かかります

Microsoftの公式な解決策は、Windows 11 ProのライセンスにアップグレードすることですMicrosoft Storeでの単体ライセンス通常価格は税込¥28,380です(2026年3月時点。最新価格はMicrosoft Store公式ページでご確認ください)。

ただし、このアップグレードにはいくつかの落とし穴があります。

PCが複数台あると費用が倍になる 自宅と職場、両方のPCをホストにしたい場合は、それぞれにライセンスが必要です。

アップグレードしてもVPN設定が必要になる Proにしても、インターネット越しのリモートアクセスにはVPN設定やルーターのポート開放が必要なことがあります。これは初めての方には難しい作業です。

「リモートデスクトップのためだけに¥28,380は高い」 知恵袋でも「Proにする必要はありますか?」「他に方法はありませんか?」という質問が多く寄せられています。

Proなしで使える代替ツール3つを比較する

実は、WindowsのエディションはRDP(リモートデスクトッププロトコル)を使わなければ関係ありません。サードパーティ製のリモートアクセスツールを使えば、HomeエディションのPCでも問題なく「ホスト」として使えます。

代表的な3つをご紹介します。

How to Set Up & Use Chrome Remote Desktop: Complete Beginner's Guide | DeskIn Japan

How to Set Up and Use Chrome Remote Desktop in Japan: A Complete Beginner's Guide to CRD

What You'll Learn in This Article

This article walks through the basic setup and features of Chrome Remote Desktop (CRD), Google's free remote access tool — explained clearly for first-time users.

CRD is free, simple to configure, and integrates smoothly with your existing Google account and Chrome browser. It works across Windows, Mac, and smartphones, making it easy to get started with remote access from virtually any device.

For everyday personal use and one-off remote support sessions, it's an excellent option — though its features are limited to "Remote Access" and "Remote Support." For more advanced requirements — 4K display quality, low latency, or stable connections inside Japanese corporate networks — a professional-grade tool like DeskIn is worth considering.


Introduction

What Is Chrome Remote Desktop?

Chrome Remote Desktop (CRD) is a free remote access tool developed by Google. All you need is the Chrome browser and a Google account to remotely control another PC over the internet, from anywhere. No additional hardware is required, making it one of the most accessible ways to get started with remote desktop access.

Why Remote Desktop Is Useful in Japan

Hybrid work has become a fixture across Japan's working culture. Many companies — especially in Tokyo and other major cities — now expect employees to split their time between the office and home. Students, too, often find themselves needing access to files or software left behind on a home PC. And for those who have just joined the workforce as shinshakajin (新社会人 — literally "new members of society," the term for fresh graduates entering their first job, typically in April when Japan's fiscal and academic year begins), juggling unfamiliar tools across multiple environments can be genuinely stressful. Chrome Remote Desktop offers a practical, low-barrier solution for all of these situations.

Which One Is Better, Chrome Remote Desktop Or Microsoft Remote Desktop?

Chrome Remote Desktop's Two Core Features

  1. Remote Access — Connect to Your Own Devices, Anytime

The "Remote Access" feature lets you connect to your home or office PC from any location, at any time. Once the host machine is configured, you can control it remotely as long as it's powered on — even if no one is sitting in front of it. This is ideal for pulling up a file you left on your home PC while you're at school or the office, or for using your full desktop environment from a laptop while you're out.

  1. Remote Support — Temporary Screen Sharing for Troubleshooting

The "Remote Support" feature is built for one-off, temporary sessions. By sharing a connection code, you can let someone else view or control your screen — or do the same for them — without exchanging account credentials. It's a clean and simple way to help a classmate, colleague, or family member work through a technical issue remotely.

Chrome Remote Desktop is designed specifically around these two functions. That focused scope makes it particularly easy to pick up, even if you've never used a remote desktop tool before.

Chrome Remote Desktop feature switching

What You'll Need Before Getting Started

A Google Account

A Google account is required. If you don't already have one, register before you begin. If you're already using Gmail or Google Drive, that same account will work here.

Google Chrome Browser

CRD runs inside the Chrome browser, so Chrome needs to be installed on both the host (the PC you want to access remotely) and the client (the device you're connecting from). Chrome can be installed alongside any other browser without conflict.

A Stable Internet Connection

Remote desktop transmits live screen data over the internet, so a reliable connection on both ends matters. If your Wi-Fi is inconsistent, a wired connection will generally produce a much smoother experience.

Step-by-Step Setup Guide

Setting Up the Host PC (the Computer You Want to Control)

Start by configuring Chrome Remote Desktop on the machine you'll be accessing remotely.

  1. Open Google Chrome and navigate to the Chrome Remote Desktop page.

  2. Follow the on-screen prompts to add the extension and complete the installation.

Chrome Remote Desktop addition and installation procedure
  1. Enable "Remote Access" and follow the steps to set a PIN code of at least six digits.

  2. Once setup is complete, this PC will appear in your list of remotely accessible devices.

Connecting from the Client Device (the Device You're Using to Connect)

Next, prepare the device you'll be connecting from.

  1. Log into Chrome with the same Google account and open the Chrome Remote Desktop page.

  2. Select the host PC from your device list.

Chrome Remote Desktop device connection screen
  1. If connecting from a smartphone or tablet, download the dedicated iOS or Android app and select your target PC from within the app.

Authenticating with Your PIN Code

After selecting the host PC, you'll be prompted to enter your PIN to verify the connection.

  1. Enter the PIN you created during setup on the client device.

  2. Once authenticated, the host PC's screen will appear on your device and you'll be able to control it with your mouse and keyboard.

  3. The connection is encrypted and can be ended at any time.

Tips for Getting More Out of CRD

Make the Most of Keyboard Shortcuts

Using keyboard shortcuts deliberately can make a real difference to your efficiency in a remote session. This is especially worth thinking about if you're switching between Windows and Mac, where key behaviour differs — particularly around:

  • The difference between the Ctrl and Cmd keys

  • Full-screen toggling and window switching

Familiarising yourself with these basics in advance will help things feel more natural. If shortcuts are being captured by your local device instead of reaching the remote machine, check the settings for an option like "Send all keyboard input to remote" — this is usually the fix.

Using CRD on Mobile: What to Expect

The mobile experience differs quite a bit from working on a desktop. Chrome Remote Desktop's mobile app is built around touch controls:

  • Swipe to move the mouse cursor

  • Pinch to zoom in or out

  • Toolbar at the bottom of the screen to access the keyboard and menu

Precise input — longer text entry, drag-and-drop, clicking small targets — is slower and more effortful on mobile than on a PC. In practice, mobile access works best for quick checks and light tasks. For anything more involved, a laptop or desktop will serve you much better.

The Limitations of Chrome Remote Desktop

Simplicity Has Its Ceiling

Chrome Remote Desktop is, at its core, a tool built for "Remote Access" and "Remote Support" — nothing more. That focus is part of what makes it easy to use, but it also means that more specialised requirements hit a wall fast. If you need to transfer large files quickly, manage multiple users or devices, or keep detailed logs of remote sessions, you'll find CRD doesn't have the tools for the job.

Instability Inside Japanese Corporate Networks

Many Japanese companies — particularly larger organisations — maintain strict internal network environments managed by their IT departments (joho shisutemu-bu, 情報システム部). Firewalls, proxy settings, and restrictions on Google services are common, particularly in finance, manufacturing, and government-adjacent industries. In these environments, Chrome Remote Desktop connections can become unreliable, suffer significant lag, or fail entirely.

If you've started a new job in Japan and found that CRD simply won't connect from the office network, this is almost certainly why.

Dependency on Your Google Account

Because CRD is tied to a Google account, any disruption to that account — a forgotten password, an account lock, or a multi-factor authentication hiccup — directly affects your ability to access remote machines. For personal use this is manageable, but for anything business-critical, it's a meaningful single point of failure.

「Windows Homeでリモートデスクトップが使えない」は、あなたの設定ミスでもPCの不具合でもありません。Microsoftのエディション設計によるものです。

公式の解決策であるProへのアップグレードは税込¥28,380かかります。しかし、リモートデスクトップだけが目的であれば、DeskInのような無料のサードパーティツールで同じことが実現できます。

セッション時間の制限なし、VPN設定不要、商用利用の誤検知なし。まずは無料プランから始めてみてください。
