Hi, thank you for that information. I'm glad it is working fine now. Moreover, if you still have the same issue going forward, I recommend doing the system restore.

Hello,
After the new KB5063842 update, my taskbar has a slight delay. When I have two tabs open and switch between them with the mouse, there is a noticeable delay, but alt-tabbing works flawlessly.
Same thing happens when I click show hidden icons via mouse on my taskbar.
I would also like to add that I have never had a problem with this.
