Stop Computer From Automatically Rebooting Overnight

Solution 1:

In Group Policy you can do something like that

To start group policy editor : Start / Run / gpedit.msc

Then / Computer Configuration / Administrative Templates / Windows Components / Windows Update

under there is a option like "No auto-restart with logged on users for scheduled automatic updates installations"

if not, you can set it to Enable. So it will inform you with tiny pop-up about restart but do nothing until you click it.

Solution 2:

My answer will depend on a couple of things

• Are you on a network that sets policies.
• Are you an do you have administrator rights to this computer.

If the Answers were in the order of "No" and then "Yes", the following fix might help you.

1. Type "gpedit.msc" in the search box in the start menu
2. In the window that shows, select "Administrator Templates" under "Computer Configuration"
3. Expand "Windows Components" and find "Windows Update"
4. Edit the "No auto-restart..." option

Solution 3:

Go to Windows Update / Change Settings, you're probably set at the default action of Install updates automatically. Change that to one of the other settings and it will resolve your problem.
