Hello,
Sorry to hear you are having issues. Please try, uninstall AltTabby, reboot immediately (important), download latest version available in your account product download page: https://store.stardock.com/myaccount/products. Install it, reboot immediately again. Retest it and report back.

If the issue still appear, we need few more details.

  1. Windows 11 full version and OS Build number. Use Winver.exe to get these numbers.
  2. AltTabby full version number installed.

Thank you,
Basj,

Your issue is AltTabby deactivate after you reboot your system, yes? So you needed to activate it again? Please refer to this guide: https://support.stardock.com/space/SHC/1260552209/Error:+212+or+Product+Keeps+Prompting+to+Activate
