如何從 Mac 遠端連線到 Windows 電腦：四種方法【最新版指南】

If you have ever tried to remotely access a second laptop from your Windows Home PC, only to be told that your Home edition does not support Remote Desktop, you already know the frustration. Three pain points hit hardest. First, Windows Home editions can't serve as Remote Desktop hosts, so your desktop/laptop can never be the host. Second, the only official fix is upgrading to Windows Pro, which costs an extra US$99 per licence. Third, Microsoft’s own Remote Desktop client apps are being discontinued through 2025 and 2026, leaving Home users with even fewer built-in options than before. The good news is that affordable (and in some cases free) alternatives exist. Here is what changed, how it affects everyday users, and which tools can get you back in control.

Before: What Windows Home Users Expected

When most people buy a Windows laptop, they assume they are getting the full Windows experience. Remote Desktop Protocol (RDP) is a native app that has been part of the Windows OS for over two decades. But Microsoft reserves the RDP host function, the ability to accept incoming remote connections, for Windows Pro, Enterprise, and Education editions only. Windows Home can only act as a client, meaning you can connect out to a Pro machine, but nobody can connect in to yours.

For designers who need to reach a powerful desktop from a lightweight travel laptop, for students who left a file on their home PC, or for anyone helping a family member troubleshoot remotely, this is a real gap. The assumption was always “I’ll just remote in.” The reality is that Windows Home quietly says no.

The Real Cost of “Just Upgrade to Pro”

Microsoft’s official answer is to purchase a Windows 11 Pro licence. A fresh Pro licence retails at US$199, while the in-place upgrade from Home to Pro costs US$99. If you own more than one machine—say a home desktop and a personal laptop—those costs add up quickly. For freelancers, students, and privacy-conscious home users, that is a steep bill just to unlock one feature. And even after upgrading, configuring RDP for use outside your local network still requires VPN setup or port forwarding, tasks that are far from beginner-friendly.

After: The Phasing Out of Microsoft’s Remote Apps Adds Urgency

To make matters worse, Microsoft retired the Remote Desktop Store app in May 2025 and will end support for the standalone MSI Remote Desktop client on 27 March 2026. Both are being replaced by the new “Windows App,” which focuses on cloud services such as Azure Virtual Desktop and Windows 365. The classic built-in tool (mstsc.exe) remains supported, but it still cannot turn a Home machine into a host. For everyday users who relied on Microsoft’s own apps to bridge devices, the transition adds confusion and reinforces that third-party software is now the practical path forward.

Solution: Third-Party Remote Desktop Tools

The simplest fix is to skip RDP entirely and use a remote access application that works regardless of your Windows edition. Three products are worth comparing and use AES-256 encryption as standard (even for financial institutions).

AnyDesk still technically offers a free tier for personal use, but recent restrictions have made it hard to rely on. Users report that sessions now disconnect in as little as five minutes, down from the 30 to 40 minutes previously allowed. File transfer has been removed from the free version entirely. The free tier is also capped at three devices, with only one session at a time. On top of that, AnyDesk’s commercial-use detection regularly flags and disconnects personal users who have done nothing wrong. Paid plans start at US$14.90 per month.

TeamViewer is one of the most recognised names in remote access. Its free tier covers personal use and includes encryption, file transfer, and multi-platform support. TeamViewer’s large user base means guides and troubleshooting resources are easy to find. However, it suffers from the same commercial-use detection problem as AnyDesk: personal users frequently get flagged and must appeal to regain access. Its paid tiers are also priced for business budgets rather than individual users, approximately around US$58.90 a month

DeskIn takes a different approach. Its free plan gives you full remote control of up to three devices at 1080p 30 FPS, with no session time limits and no commercial-use flags that cut you off mid-task. For the Windows Home user who just needs to reach a file on another PC, help an elderly relative troubleshoot, or check in on a home PC while travelling, the free plan covers it. It connects devices through its own cloud relay, so there is no need for VPN or port forwarding. File transfers run up to 12 MB/s with no size cap but limits to computer-to-phone transfer. The cross-platform capability allows you to control your home PC from a phone, or extend your laptop display to a tablet, all without a Windows Pro licence. 

For users who need more, paid plans start from US$9.90 per month with higher resolution streaming, faster file transfers, and support for up to 100 devices

DeskIn: Full Remote Access for Free

All three tools restore the remote control ability that Windows Home withholds. AnyDesk and TeamViewer are familiar names, but their free tiers have become increasingly limited: short session caps, removed features, and unpredictable commercial-use flags make them hard to count on for regular use. If you need colour accuracy for design work, transfer large project files every day, or simply want a reliable remote access experience without networking headaches, DeskIn offers the most complete set of features at a reasonable price, and its personal tier is free to start.

Upgrading to Windows Pro is still a valid option if you need RDP and other Pro features. But if remote desktop access is the main reason you are considering the US$99 upgrade, DeskIn offers a free alternative with low-latency connections that works on any Windows edition. Download DeskIn for remote work or explore its productivity features if this is the right tool for you before spending on a licence upgrade.

Image alt: Free Unattended Remote Access Software TeamViewer

TeamViewer has been one of the most recognizable names in remote access for nearly two decades, and for good reason. It offers a mature ecosystem that supports Windows, macOS, Linux, Android, and iOS, making it highly versatile across devices. For small businesses, especially those with distributed teams, it provides structured device management, session logging, and secure, encrypted connections.

In terms of unattended remote access, TeamViewer allows users to configure permanent access credentials so machines can be accessed anytime they are online. However, users relying on the free version often report limitations related to "personal use" detection, as well as occasional version-mismatch issues that can temporarily block access. While it remains a powerful option in the free unattended remote access software landscape, it may feel feature-heavy for individuals who simply need stable, always-on remote access without licensing concerns.

Best for IT Teams: AnyDesk

Pros

• Free for personal use

• Fast performance

• Built-in file manager

• Collaboration tools

• Address book for device management

Cons

• Limited features for larger enterprises

• UI can feel structured for support workflows

Best for: IT professionals managing multiple machines

AnyDesk is widely respected for its speed and responsiveness, particularly in environments where low latency is critical. Built with a proprietary codec optimized for remote sessions, it performs well even under limited bandwidth conditions. For IT teams managing multiple endpoints, its address book system and permission controls make device organization straightforward.

As unattended remote access software, AnyDesk supports permanent passwords and background installation, allowing administrators to connect without user interaction. It also includes built-in file transfer and collaboration tools such as chat, which are useful in support workflows. That said, the interface and feature set lean toward professional IT use cases rather than casual personal users. For those specifically searching for the best free remote desktop software for unattended access in structured IT environments, AnyDesk remains a strong and reliable contender.

Best Remote Access for Individuals: Chrome Remote Desktop

Pros

• Completely free

• Extremely easy setup

• Works inside the Google ecosystem

• Cross-platform

Cons

• Limited features

• Requires a Google account

• No built-in file transfer

Best for: Individuals who want simple Chrome remote desktop unattended access.

Chrome Remote Desktop stands out for one primary reason: simplicity. Setup typically takes only a few minutes. Users install the browser extension, link their Google account, set a PIN, and can immediately enable Chrome Remote Desktop unattended access for ongoing connections. There is no complicated network configuration or advanced setup process involved.

However, while Chrome Remote Desktop works well for light, individual use, it offers minimal management tools. There is no built-in file transfer feature, and functionality remains intentionally basic. For users who travel frequently or need occasional access to a home PC, it serves as an accessible entry point into free unattended remote access software. But for managing multiple systems or performing advanced troubleshooting tasks, its limited feature set may become restrictive over time.

Best Remote Built-In Windows: Microsoft Remote Desktop

Pros

• Integrated into Windows

• Full control of the remote device

• File transfer supported

• No third-party installation needed

Cons

• Complex setup outside the local network

• May require VPN or port forwarding

• No cloud relay

Best for: Advanced Windows users.

Microsoft Remote Desktop is integrated directly into Windows, making it a natural choice for users seeking free remote desktop Windows 11 or free remote desktop Windows 10 functionality without installing third-party tools. Within a local network, setup is straightforward, and performance is stable, offering full desktop control, file access, and administrative capabilities.

For unattended remote access scenarios, it can be configured to allow remote login without user approval. However, accessing a machine over the public internet often requires additional setup, such as VPN configuration or port forwarding, which may be challenging for non-technical users. While extremely powerful in professional Windows environments, it is generally better suited for users comfortable with networking concepts rather than beginners looking for plug-and-play remote access.

Note

Microsoft has retired its separate Remote Desktop app (from the Microsoft Store) and is ending support for the standalone Remote Desktop client (MSI) in March 2026, replacing both with the new Windows App for cloud services like Azure Virtual Desktop and Windows 365. However, the built-in Remote Desktop Connection (mstsc.exe) that ships with Windows 10 and 11, which is what we're recommending here, remains fully supported and unaffected by these changes.
