Prevent Windows Update from Forcibly Rebooting Your Computer

Prevent Windows Update from Forcibly Rebooting Your Computer

We’ve all been at our computer when the Windows Update dialog pops up and tells us to reboot our computer. I’ve become convinced that this dialog has been designed to detect when we are most busy and only prompt us at that moment.
There’s a couple of ways that we can disable this behavior, however. You’ll still get the prompt, but it won’t force you to shut down. Here’s how to do it....


Manual Registry Hack
Open up regedit.exe through the start menu search box or run dialog, and navigate down to the following key, creating new keys if they don’t exist.

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU

Create a new 32-bit DWORD value named NoAutoRebootWithLoggedOnUsers and give it a value of 1 to prevent automatic reboot while users are logged on. Delete the value to put things back to the way they were.
