Windows Update Restart Error
Scenario
You have either just installed a Windows operating system on your computer or upgraded to a different version and while you wait for the update to complete, you are met with an error window telling you "The system has restarted unexpectedly". You then follow the instructions on screen and restart the system to continue, but the error still pops up causing a loop with the Windows update error message.
​
Don't worry, I have you covered. I was met with this error myself and managed to resolve it with just a few steps, scroll down to see what you can do to get your PC back up and running in minutes.
How to solve
Step 1.) When the error message window appears, press Shift + F10 to get a Command Prompt Window
​
Step 2.) In the Command Prompt window type "regedit" then press enter
​
Step 3.) Navigate to the following folder:
HKEY_LOCAL_MACHINE/SYSTEM/SETUP/STATUS/ChildCompletion
