The issue and the workaround I have found works):-
Noticed that Task Manager in both User and Admin logins launches as normal, but when closing it the white background window (with control buttons) remains for c.8-20 seconds (depending on cpu utilisation), plus cpu % climbs to 100% in steps after the first 4-seconds
Taskbar is a bit slower also, but not quite as bad…although improvement is noticeable if you are looking for it.
I tried an update to latest Nvidia drivers, I removed the existing ones using latest DDU in safe mode first (with ethernet cable out as well) (v517.xx)– no change…
I ran SFC/SCANNOW and ‘DISM /Online /Cleanup-Image /ScanHealth’ both found no problems
The issue is so specific, i.e., only the Taskbar Tray Icon area is slow to load (the translucent
background loads first then the black menu).
*****[WORKAROUND – Turn OFF the Taskbar Search Box, i.e. ‘Search Icon Only’]*****
NOTE:-
- I found this out by first limiting my use of the notifications tray area (where the clock lives for newbies) by making all the most important tray icons to stay always visible, but then I wanted to make some more room on the taskbar so changed from the ‘search box’ to the search icon only option on the task bar context menu.
- I have tested this issue with it on and with off (see also below); it immediately returns when ON and immediately disappears when OFF.
- This was repeatable between
- Multiple restarts and cold starts.
- Between both my computer accounts; i.e.; both the local administrator and the standard local user account (daily driver).
- I have informed MS via Feedback hub, hopefully they fix this annoyance.
- For ref. system spec (Win10 Pro 21H2, AMD R5 3600X, 32GB Corsair Vengeance 3200CL16, Samsung 970Pro, Gigabyte Aorus Pro Motherboard + 1660Ti Windforce OC, so not esoteric spec machine!
