Hello,
I confirm the Randomly freezes since version 2004 (official version and not insider version).
Since the last build 2004 update (June 10, 2020), my computer has become an unbearable freeze and slow disaster.
I tried to uninstall the last unstable patch with
wusa / uninstall / kb: 4557957 but unfortunately there was a purge.
In addition, I found that Windows becomes more and more very anxious and very penalizing when we work, it is unthinkable and I am ready to leave Windows if I would not have the fixes this week Tuesday evening at the latest. Because I am now very late and I have lost 3 weeks of this greedy bug bugs!
