Hi @Ashadmccloud181,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

Thanks for reaching out! The error message, “The computer restarted unexpectedly or encountered an unexpected error “, usually appears during or after a failed Windows installation or update. It prevents the system from booting properly and can loop indefinitely unless fixed.

Here's How to Fix It

1. Use the Shift + F10 Method (Command Prompt Fix)

1. When the error message appears, press Shift + F10 on your keyboard.
   • This opens Command Prompt.
2. In the Command Prompt window, type the following and press Enter: regedit
3. In the Registry Editor, navigate to: HKEY_LOCAL_MACHINE\SYSTEM\Setup\Status\ChildCompletion
4. On the right side, double-click the entry named setup.exe.
5. Change the Value data from 1 to 3, then click OK.
6. Close the Registry Editor and Command Prompt.
7. Click OK on the error message to restart your computer.

If That Doesn’t Work

Option 1: Perform a Startup Repair

• Boot from a Windows 11 installation USB.
• Select Repair your computer > Troubleshoot > Startup Repair.
   

Option 2: Reset the PC

• From the same recovery menu, choose:
  • Troubleshoot > Reset this PC > Keep my files

I hope this helps.

Take care and have a good day.
