This website is about 7+ Taskbar Tweaker, not Windhawk.

Windhawk doesn't do permanent changes to the system. If you disabled the mod, restarted, and you still experience issues, then it's unrelated to Windhawk.

7+ Taskbar Tweaker in no longer supported on Windows 11 version 24H2, see:

Many of the 7+ Taskbar Tweaker options were ported as Windhawk mods. Some of them support the ExplorerPatcher taskbar too, if you prefer to continue using the Windows 10 taskbar.

Glad to hear that it's sorted. Let me know if there's an issue with one of the Windhawk mods.

Is it related to the start button issue, or to 7+ Taskbar Tweaker at all? Please provide more details or create a new ticket if it's an unrelated issue.

Are you using Windows 10 or Windows 11? Also, please post a screenshot to show how it looks for you.

Edit: I just tested this on an up-to-date Win10 build (19045.5679) and it works as expected for me with multiple monitors.

The “Open With” feature is a built-in feature of Windows, not a feature that the tweaker adds. You can activate it by holding the Shift button. All that the tweaker does is making Windows think that you’re holding the button.

The "Middle click to mute" option requires Windows 11 version 22H2 or newer, and isn't supported for the old taskbar if a tool such as ExplorerPatcher or StartAllBack are used. If you think it should work, please create an issue here:

Regarding the "especially" word you used, what other issues are there? Please report any issue on GitHub with the relevant details.

Which version of StartAllBack is being used? Versions 3.8 and newer aren't supported, see:

The solution for error 102 is to reinstall the tweaker, as the error message says. Please reinstall and let me know if the error persists.
