After experiencing a disappearing start button and a taskbar that would not move from the top of the screen back to the bottom despite applying changes to Start11 preferences, I tried to uninstall your Start11 software.  Unfortunately, your uninstaller did NOT restore the OS to the pre-Start11 installation sate:

* The taskbar remained at the top of the screen

* The start button remained left-justified

* The size of the taskbar was not restored to the original size (it remained "small")

I'm not sending screenshots as they are pointless in this case (please don't reflexively ask for them):  they would display a small taskbar at the top of the screen with the start menu left-justified (the state after software uninstallation).  This is what your software is designed to do and a picture would provide no additional technical information needed to fix the problem.

Microsoft Windows [Version 10.0.22000.613]

Start11 installer is latest version (I'm not reinstalling the software to provide the version number as I've already run the uninstaller).  I downloaded the installer within the past three days.
