THank you so much, people.
Everything is going so slow on that computer I am having problems finding the "Command" prompt. Where do I find that? Sorry I should say I am running this in the German language. Computer is so screwed I cannot make a screenshot. (Task manager seems to find nothing huge.)
I did a "search" for "Command" and cannot find it. I hope it is called the same in German. Sorry to be stupid. Is it under "System"?
I believe the last update HAS been installed; it tells me that one was done on 12.9. I got a little message that a 560KB (yes KB!) large windows update was available today, I seemed to have gotten that installed, it took about 20 minutes, and things are just as bad as before.
Can you tell me where exactly I can unistall a windows update? Is that a page like a website page? And there I can choose to click "uninstall latest update"? Hoping, of course, that this is the source of the problem.
I'm sorry for being an idiot. Thank you, people.
