Unwanted reboot - Andrew-T

Three times since Christmas my desktop PC, running Windows 10 and Chrome, has spontaneously rebooted, each time while I was idling in the Back Room here. That seems rather a coincidence. Any suggestions?

Have you checked when your getting win 10 updates as they do restart the machine without your consent, there have been several over Christmas

Unlikely a website will cause it unless it crashed

Agree, there was a Windows update before Christmas. Don’t however do it if you need the machine, it took over an hour to install on my laptop last night!

Under win 10 update settings you can select when updates are installed.

If you have a slow system or slow internet this will imact on the time taken for any update

Only an hour! Took mine 4 hours after running like a dog fo ages beforehand, then next day it started doing even more updates for a further 2 hours. It was my spare laptop, but I've now set it to not restart altough I still can't see a way to simply stop it doing updates.

What really displeases me is the reboot time. When I first got the laptop 3 years ago it took 45 seconds to reboot. Now it takes 11 minutes!

Time for a format!

Or find out whats causing bootup to take so long, ie, some have antivirus set up for boot scan, which, depending on make can take ages?

Third party AV utilities are allways the last to load.

A laptop, unless a very expensive model, will allways be significantly slower than a desktop

Ctrl+Alt+Del brings up task manager that has a 'start-up' tab that would be worth looking at
