For about 2 months I have noticed that files that I have in a folder I have created on the desktop keep disappearing - I've watched it long enough; human failure is impossible! - I definitely didn't move anything, accidentally deleted it, etc.). The folder and file structure in the main folder is still preserved, but then no longer contains any data (only empty folders). Thank god I have the folder as a copy on the external hard drive and I have already pulled it over a couple of times. It seems to go well for several days and then the files are gone again.
Now I have come to the conclusion that the point in time of this error could fit in with other installations / updates etc, which each required a restart (not 100% sure). I now suspect that the files disappear every time I restart.
Since 12.12. (The day before there was an update) I also had the problem that my notebook started up very, very slowly (about 11 minutes). I have alleviated this problem to the extent that I have switched from HDD to SSD hard drive and it now "only" takes 30 seconds. I can still live with that, but the disappearance of files and, accordingly, now paranoid permanent security copying to external FP or cloud is not an acceptable state! I've already tried various tools such as sfcscannow, DISM… Check health etc, especially since there were also some problems with file paths (I don't really know that). Oh yes, virus scan reports nothing; have Norton installed. So far it has also been great.

Have you ever done a complete scan for defective blocks with HDTune?
No, is that a tool to install (or a cmd command)?
I think it is impossible that the update is the cause but if you want to be sure you can uninstall the update
Well, in this case that can't be done without affecting all subsequent updates, at least that's how I googled it.
Most updates are not interdependent because they update completely different parts of the system
