Here’s a bug in Windows explorer that I happened to notice today, which has zero value and despite me trying to find a way to abuse it, is seemingly completely useless. Tested on Windows 10 22H2 & Server 2019/2022.

If you right click on the start menu icon in the task bar, the task bar across all screens freezes in time. The clock doesn’t update, applications that open after you right click don’t show up on the task bar as being open (except in Server 2022), but when you click away from the right-click menu everything snaps back to the correct state.

Right clicking on other things in the task bar doesn’t yield the same results. It’s only the start menu icon.

EDIT: Does not affect Windows 2012R2.
