When I was using paint.net my computer suddenly began restarting. There was nothing I could do to cancel it, and there was no warning.
After my system was restarted, I looked in the event viewer and saw this:
Please don't restart my system just because you need to update.
And also, I had disabled the automatic check for updates in paint.net, but that didn't seem to have any affect.
After restart, paint.net is in version 4.2.8 (I don't know which version I was using before the reboot). I'm using WIndows 10.
