Windows 10 20H2 feature update causes lags, freezes, slow performance

I installed the Windows 10 20H2 update about a week ago, and since then my computer constantly freezes. These tasks aren't computationally demanding - watching videos in the browser or Spotify etc. I read there were some known issues with the update affecting network connectivity as well as general performance issues, but I've tried to install the patches for this and they're "not applicable to my device".

I have a series of driver updates but nothing else in my "optional updates" section. Should I try these? Are there pending patches for this update yet to be released? Worst case scenario, can I just roll it back completely?

    Same here but it disappears after restarting. Interesting.

    Here is my two cents on this matter.  All of this is IMHO and not based on any cause and effect.

    I have been dealing with a system slowdown for weeks hoping an update will put it back the way it was in Jan.

    My metric is using the Mouse panel in Settings. It can take 3-10s for me to make a change in the cursor speed. Sometimes while sweeping across the screen the mouse cursor will stutter or halt for a part of a second and then jump a short bit. I guess to catch up. Note that the  old fashioned Sound control panel does NOT have that slowness problem. It works great. Clearly they don't make software like that anymore.

    I have done a cleanboot, and that stopped a small amount of the lag but it is still there. I can't see anything in Task Manager that is doing large amounts of CPU work. I see this lag when Task manager says the CPU is 3% busy. I say Windows is wasting some time in a way that is observable but not detectable by the CPU use. I am not doing any of the DISM or Upgrade junk. It has taken many hours of my time doing that six times in the last two years and NEVER helped.

    I am waiting as this will just go away or morph into a better or worse symptom after one or a dozen updates.

    Some testing here. Most of my apps have some sort of Chrome (which is based on Webkit) in the background. Lots of apps, including Discord and Slack use Electron as their backend, which runs on top of Chrome.

    So, I switched my browser to Firefox. No lag or stutter, so I switched. These apps (perhaps more) do:

    Task Manager
    Steam Friends (but not Steam itself)
    Chrome
    Edge
    Discord (Electron)
    Slack (Electron)
    Spotify
    Facebook Messenger
    VS Code (Electron)

    The commonality between these all, except perhaps Task Manager, is the webkit base.

    Here's a recent related bug https://bugs.chromium.org/p/chromium/issues/detail?id=1061465 but I suspect something Microsoft did is still the culprit underneath, since this did not happen until the update.
