Version 5.15.2 was released yesterday, please update.

From version 3.8, StartAllBack uses its own taskbar, so 7+ Taskbar Tweaker doesn't work with it.

Currently, you can either stop using StartAllBack, stop using 7+ Taskbar Tweaker, or stick to an older version of StartAllBack before 3.8.

Are you using ExplorerPatcher, StartAllBack, or something else? Which version?

Hi, 7+ Taskbar Tweaker only works with Windows 11 if the old Windows 10 taskbar is used. Does 24H2 still contain the old taskbar code? Which method did you use to revert to the old taskbar?

Did you install the mod and then tried that? The mod only affects re-order events which happened after the mod was installed. That means that as long as the mod is active from the beginning, it should work, but if it was installed at some point while there are open windows, it won't remember the order for them.

A quick test to check that the mod works is to follow the steps in the short video here:
