Run Startup Repair to stabilize Windows first, then use a clean boot to identify the software or service interfering with startup; stop cross-device synchronization and remove Xbox components separately afterward.
1. Repair startup without repeated forced shutdowns
Repeatedly holding the power button risks file-system and data corruption.
When the computer enters the Windows Recovery Environment:
- Select Troubleshoot.
- Select Advanced options.
- Select Startup Repair.
- Select Restart.
- Allow the scan and repair to finish.
Startup Repair checks problems including damaged system files, boot configuration, registry errors, and incompatible drivers. A BitLocker recovery key may be required if device encryption is enabled.^1^
If Windows never displays recovery options, create Windows 11 installation media on another working computer, boot the tower from it, select Repair my PC, and then open Troubleshoot > Advanced options.^2^
2. Determine whether startup software is causing the failure
The Xbox app has not been established as the cause. A clean boot will distinguish a third-party startup conflict from a Windows or hardware problem.
- Sign in using an administrator account.
- Search for msconfig and open System Configuration.
- On Services, select Hide all Microsoft services first.
- Select Disable all, then Apply.
- Open Startup > Open Task Manager.
- Record the enabled items, then disable them.
- Close Task Manager, select OK, and restart normally.
Do not change the advanced boot options in System Configuration. The computer may temporarily lose some nonessential functions during this test.^3^
- If startup now works: Re-enable half the disabled services and startup items at a time, restarting after each change. Repeat until one item reproduces the problem. Leave that item disabled or uninstall its associated program.
- If startup still fails: The problem is not isolated to third-party startup software. Continue with the driver checks below.
- When finished, open msconfig, select General > Normal Startup, and restore the items that were not responsible.
3. Stop the desktop inheriting settings from the Galaxy Book
Windows Backup can synchronize installed-app information and preferences across devices signed in with the same Microsoft account. Other Windows settings can include printer and mouse options; this is preference synchronization, not the transfer of the laptop’s physical hardware or drivers.^4^
On both computers:
- Open Settings > Accounts > Windows backup.
- Turn off Remember my apps.
- Expand Remember my preferences.
- Clear Other Windows settings, plus any other categories that should remain device-specific.
- If files should also stop synchronizing, select the OneDrive cloud icon beside the clock, then Settings > Account > Unlink this PC.^5^
To remove previously stored settings, open the Microsoft Account Devices page, find Cloud synced settings, and select Clear stored settings.^4^
4. Remove unwanted Xbox software
This is separate from repairing the startup failure:
- Open Settings > Apps > Installed apps.
- Search for Xbox.
- For each Xbox app you do not want, select … > Uninstall.
- Open Task Manager with Ctrl+Shift+Esc.
- Select Startup apps and disable any remaining unwanted Xbox-related startup entry.
Windows documents the same Installed Apps removal path for unnecessary applications.^6^
5. If the keyboard and mouse still disappear during startup
- Connect a basic wired keyboard and mouse directly to rear motherboard USB ports, without a hub.
- Open Device Manager and check Keyboards, Mice and other pointing devices, and Universal Serial Bus controllers for yellow warning symbols.
- Open Settings > Windows Update > Advanced options > Optional updates.
- Install relevant keyboard, mouse, chipset, or USB driver updates and restart.^7^
If a blue/black error screen appears, photograph the exact stop code and any displayed driver/module name. Windows identifies hardware, drivers, and software as possible causes of repeated stop-code restarts; that code is needed before attributing the crashes to Xbox or another component.^8^
