Hello, first post here in the forums

I'm a newbie who's trying to fix the same problem that was shown here in the original post.
I have some knowledge in computers but not too fancy (so please don't use too big of a words

)
My laptop has been slowing down for the past while and when opening the task manager I could see it's one of the SVCHOST.exe there. When opening the Memory tab in Resource Monitor I saw that it's SVCHOST (netsvcs).
It seems to take up between 500,000 K and 2,050,000 K of memory (as I can see in the Task Manager).
After seeing that the process keeps on rising with the memory use, I've tried ending the process.
Everytime I end the process, the screen "blinks" and the graphics of Windows changes a bit (like a bug). After the 3rd time of ending the process, Windows goes into "Classic Windows" mode, makes it look like the older Windows (95/98/2000...) and the possibility of the original Windows 7 style is now blocked (grey and not pressable).
I've figures it might have something to do with my graphics but I don't know.
I've searched all over and couldn't find any answer.
Any idea? I've seen it happens to many others, but I either can't fix it, or can't understand how to.
Thanks in advance!
