Win10 -2004, Slow - is it fixed?

Not just one program - anything I tried to do - open Explorer, for example. The entire machine basically was so slow it was unusable.

That could have been caused by Microsoft Defender. Try to temporarily install 3rd party AV, like Adaware.

If you encounter this again, using the various tabs on the task manager to see what's happening can be instructive- excess resource use, disk usage etc..

That was probably quite a decent time for the roll-back by the way. It's a significant change.

Just look at the incredible list of things fixed- including various issues of slow response and blue screens- here:

KB4571744 Cumulative Update Windows 10 v2004 build 19041.488 - Sept. 3

Could any of these apply or have applied to you? Do you have this installed?

I updated my second PC to v.2004, yesterday. There is nothing slowing it down! I'm truly happy about this outcome.

I have drop in 2D graphic performance, it dropped sharply after installation, changing drivers didn't help any. It's barely noticeable normally but work with pictures suffers a bit. Benchmark shows about -30%.
