Just to add to the topic...
Today I was using Youtube and all of sudden the mouse slowed up as if there was a virus attack. I had noticed pages were buffing before this happened. When it freed up enough to use the mouse I went straight to Task Manager and saw an app or program called "feed" or "search" and it was using +90GB RAM out of 128GB of RAM. I selected end task and it slowly released the RAM it was using. System is running ok right now. That was scary!!!
This is what I am running:
Edition Windows 10 Pro
Version 21H1
Installed on 21/09/2021
OS build 19043.1526
Experience Windows Feature Experience Pack 120.2212.4170.0
