Get rid of that “Restart Now” dialog box

Windows is quite the nagger. Do this, Restart Now, Save Later… BLAH BLAH BLAH. However if you IGNORE it’s restart dialog warnings Windows will do you the favor and restart on its own, closing all your important documents. Time to take control back! With this hack you can tell Windows how often to nag you (default is 10 minutes), or to turn off the nag entirely. SCORE!

Now, to get rid of it:
Start / Run / gpedit.msc / Local Computer Policy / Computer Configuration / Administrative Templates / Windows Components / Windows Update / Re-prompt for restart with scheduled installations

You can configure how often it will nag you (I re-configured it for 720 minutes, which means I’ll be asked twice on a work day), or completely disable it.

Oh, I almost forgot: this setting is only loaded when Windows starts, so a reboot is needed. If that stupid dialog is on your screen now, just stop the “Automatic Updates” service (but keep it as Automatic, so it gets reloaded on the next start) and you won’t see it again.[via]
