The Windows start menu button disappeared from the taskbar. First thought it was a Windows 10 update issue and searched for solutions.  I recently purchased a new version of Start10 and then two Start10 programs were listed in the apps list.  I uninstalled Start10 and the windows menu button reappeared. Reinstall of Start10 loses the Start Menu Button again so had to uninstall once again.  Stardock Start10 1.75 still shows in the Apps list but neither "Modify" or "uninstall" work.  I paid for the program and want to use it but need a windows icon button on the taskbar for access.
