Windows Update booting PC during night

After every new Windows installation, I ran into the problem that Windows Update boots my PC during the night for the installation of updates and my battery is nearly empty the next morning.

Per default, Windows Update boots the PC and installs updates around 3:00 AM.

To change this, go to

Windows Update > Change Settings and click on “Updates will be automatically installed during the maintenance window.”


In the following dialog, disable “Allow scheduled maintenance to wake up my computer at the scheduled time”
