Now, Microsoft is expanding those controls. As reported by Android Authority, Mezha, and PCMag, Microsoft has begun rolling out remote PC power management to beta testers of the Link to Windows app for Android. Arriving in beta version 1.26101.103.0, the update upgrades the mobile companion app from a basic session lock tool into a remote power switch capable of putting a connected Windows PC to sleep, restarting it, or shutting it down completely.
Inside the Link to Windows Beta 1.26101.103.0 Update
For most of its existence, the pairing between the Phone Link app on Windows and the Link to Windows app on Android has focused on bringing mobile conveniences to the desktop—syncing notifications, handling SMS messages, fielding phone calls, sharing a clipboard, transferring files, and turning a smartphone into a wireless webcam. Control in the opposite direction—managing the PC from the phone—was limited to a standalone Lock PC button on the Android app's main screen.
In Link to Windows beta build 1.26101.103.0, that single lock button has been replaced by a consolidated Power menu. Tapping the Power button presents four core system commands:
- Lock PC: Secures the active Windows session behind the lock screen while keeping applications running in the background.
- Sleep PC: Places the computer into a low-power sleep state.
- Shut down: Closes all software and powers off the machine completely.
- Restart: Reboots the operating system.
If your computer happens to have a pending Windows Update queued in the background, the mobile menu adapts dynamically. As PCMag and Mezha note, the app surfaces Update and shut down and Update and restart options, allowing you to clear out patch installations remotely before the machine powers down or reboots.
| Power Command | Remote Effect on Windows PC | Keeps Phone Link Connection Alive? | Risk of Losing Unsaved Work? |
|---|---|---|---|
| Lock PC | Locks current user session | Yes | No |
| Sleep PC | Enters low-power sleep state | No (Requires manual wake in person) | Low (Session stays in memory, unless power fails) |
| Shut down / Update and shut down | Closes apps and powers off hardware | No | High (Cannot save open files from phone) |
| Restart / Update and restart | Closes apps and reboots Windows | Temporarily disconnects during reboot | High (Cannot save open files from phone) |
Section Summary: Link to Windows beta 1.26101.103.0 replaces the single Lock PC button with a four-option Power menu, adding remote sleep, restart, shutdown, and Windows Update completion commands for Android users.
The Catch: Unsaved Data and the One-Way Sleep Trap
While triggering a shutdown from the couch is undeniably convenient, Link to Windows is not a remote desktop viewer. You cannot see your open windows from the power menu, nor can you click "Save" on an open spreadsheet or document from your phone.
Microsoft built explicit warning prompts into the workflow to prevent accidental data loss. According to PCMag's reporting on the beta interface, selecting the shutdown or restart options triggers an alert reading: "You may have unsaved data on your device. Make sure you’ve saved any open work on your PC," accompanied by a reminder that you cannot save files remotely through the app.
If you suddenly realize you left an unsaved document open on your desktop, the Sleep PC option is the safer fallback—with one major operational caveat. As soon as the PC enters sleep mode, its connection to your smartphone is severed. The app warns users that it does not support remote wake-up (such as Wake-on-LAN), meaning you cannot use your phone to wake the PC back up later; you will have to physically return to the computer to resume your session.
If you need the computer to remain reachable from afar, or if it is running background tasks like media rendering or file transfers, sticking with Lock PC remains the right choice.
Section Summary: Because users cannot view or save open desktop files through Link to Windows, the app warns that shutting down or restarting can cause data loss. Putting the PC to sleep preserves open work but severs the connection with no way to wake the PC remotely.
From Hidden Code to Beta Testing: Rollout and Compatibility
This feature did not appear out of nowhere. In late August 2026, code examinations by Windows Latest and Android Authority uncovered dormant strings tied to a RemoteControlManager component inside an Android APK teardown of Link to Windows. At the time, the strings referenced "Restart," "Shut down," "Sleep," "Update and Restart," and "Update and Shutdown," though the controls were non-functional. Roughly six weeks later, Microsoft has activated those exact strings for beta testers.
Before you grab your phone to test it out, keep the current platform boundaries in mind:
- Beta Exclusivity: The Power menu is currently limited to beta testers running Link to Windows version 1.26101.103.0 on Android. It has not yet reached the general stable channel, and Microsoft has not announced a timeline for wide availability.
- No iPhone Support: While Microsoft offers a Link to Windows companion app for iOS, PCMag reports there is currently no evidence that remote power controls are in development for Apple devices.
- General Phone Link Prerequisites: While Microsoft has not published a dedicated hardware compatibility list specifically for the beta power menu, standard Phone Link operation on Android requires a PC running Windows 11 (or Windows 10 with the October 2022 Update or later), an Android device running Android 10 or later, both devices signed into the same personal Microsoft account, and an active connection to the same Wi-Fi network.
Practical Takeaways for Windows Users
For everyday Windows 11 users, remote power controls are a welcome quality-of-life upgrade that bridges a noticeable gap in Microsoft's cross-device ecosystem. You no longer need to configure third-party Remote Desktop apps, SSH servers, or smart plugs just to turn off an idle PC at the end of the night.
To get the most out of the feature when it lands on your device, follow three simple rules of thumb:
- Make
Ctrl + Sa habit before walking away: Because Link to Windows cannot save open files for you, get in the habit of saving your work whenever you step away from your desk. - Use "Update and shut down" strategically: If Patch Tuesday leaves a restart pending, triggering the update-and-shutdown sequence from your phone lets your PC install updates and power off overnight without keeping you waiting at your desk.
- Know when to Lock vs. Sleep: Use Lock PC if you plan to return shortly or need the phone link to stay active; use Sleep PC if you left unsaved work open and want to cut power draw until you return in person; and reserve Shut down for when you know your session is clean and ready to close.
