AMD TR 7980X explorer problem - copying problem

Hi,

I have a problem with my new Pc. I found that problem after I plug in all my drives.

When I start Pc, everything is ok, SSD and M.2 are fast as they should be. But after a while when I am working and then start to copy something - doesnt matter which disk I use - it copy around 3s with high speed and then it slows down to about 80 MB/s and CPU usage raise to about 36 percent. And after that it behave like that until I restart. I looked at proceses and Explorer has about 23 percent and System about 12 percent. It looks like some kind of a bug or something. When I restart or kill explorer process it start to hebave normaly, disks are fast and cpu usage is about 1 percent. But it repeate after a while. Absolutely dont know what to do about this.

Newest Win 11 Pro 23H2
AMD TR 7980X, ASUS motherboard, 256 GB RAM, RTX 4090

I really dont want to kill explorer process every hour or so. Can someone help me please?
Thank you.

Problem in Win11. With Win 10 everything is ok so I stay with Win 10 for some time.

We have had the exact same problem with Win11 and a 7995wx. Can’t seem to figure out a solution.

With Win 10 support and security updates ending next year we’d really like to avoid going with Win 10, only to have to upgrade everything in a few months. (Of course we would really rather MS just keep updating Win 10 forever, or better yet, Max move to Linux.)

Anyone else seen this, and, more importantly, have a solution?

Yes, I want to go to Win 11 too. I think MS will fix this problem. Those new CPUs are there only for a few months. And I doubt there is any solution, MS have to fix this on their own.
