Does windows update automatically restart your pc when idle ?

I left my pc for an hours, when i came back i saw white dot circle on my screen and continue with getting update ready or windows ready message (i cant quite remember) and logon screen appear as usual. And i remember my windows downloading update couple hours ago, because i saw this on task manager.My question is, does windows update automatically install and restart your pc when idle? And when i can check this setting ?

Yes. By default updates are installed automatically. If a restart is required to complete installing an update the PC will restart automatically outside your Active Hours. When a download has installed and requires a restart to finish the install you have the option to schedule the restart for a time of your choosing, up to three days ahead. NB: this option is greyed out until an update actually needs a restart.
