KB5001330 CU Windows 10 v2004 build 19041.928 and v20H2 19042.928

Has anyone noticed those performance issues that have been reported all over? I haven't seen any change for better or worse with V-sync on, but I'm using a pre-RTX Geforce and older drivers.

My benchmarks show even some improvement.

A few people in this thread have posted in the last few days.

the nvidia forum is actually full of the performance issue allgedely introduced within the latest windows updates, where the staff itself also suggest to uninstall some..

I've read that one should leave component store alone. Is it generally safe to run that command?

You should never mess about with the component store manually, but running the commands MS provide for the purpose is the safe (in fact, the only recommended) way to manage WinSxS. Dism's CleanupComponentStore command starts the same TiWorker.exe process that is run when Disk Clean up cleans up Windows Updates, so yes, it's safe to use.

I am running on RTX 2080Ti video card and I haven't seen or felt the performance issues, but the issue after installing KB5001330 seems to be well-known out there amongst many users.

KB5001330 Windows Update is reportedly causing performance drop in games, failed installs and bootloops

Does anyone know the official (non-preview) CU KB number right before this CU?

Thanks for the link. Just to be sure, I assume it's the out-of-band KB15001649 CU which includes all the updates for 20H2 up until the current KB5001330?
