Delay the Annoying Windows Update Reboot Reminder· Windows Registry
Do you hate the little reminder to reboot your system every 15 minutes after Windows updates your system? Even though you probably should reboot just to clear up any pending operations on your beautiful, quick running PC, there is a way to prevent the reminder from showing up every 15 minutes.
Place the code below in a *.REG file and double click to set the “snooze” timeout to 24 hours instead of 15 minutes. Sorry, that’s the Microsoft limit.
Windows Registry Editor Version 5.00 ' Set to the max of 24 hours [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\windows\WindowsUpdate\AU] "RebootRelaunchTimeoutEnabled"=dword:00000001 "RebootRelaunchTimeout"=dword:00001440
