Your home directory contains a registry file. It's your profile.

Some of the changes, suggest either a profile that is starting
from scratch, or you're logging in with a different profile.

The My Documents folder was gone, because the linkage between the
My Documents and the actual storage drive was broken. The files were
still present, but on some other drive.

Sometimes, video related settings can change, because a video card
driver got updated.

I can't really make a lot out of your report. As to what is
causing this. Something is causing it. But what has gotten
into the system.

The time constant could mean just about anything. It could mean
some maintenance activity kicked off whatever is happening. Or some
program that is running a service or has a Task Scheduler entry,
has started doing something on a particular day.

Your Windows Updates is apparently normally switch off (for manual
updating). Again, not that this points to a definitive root cause.

You need to look in the Event Viewer, for something significant.

Alternately, you can use this. It shows an MS panel already
in your OS.
