I am on the latest version of Windows 10. I was somehow able to upgrade from Windows 7 to Windows 10 a few years ago with HP ProtectTools installed. Now I am trying to uninstall it. It is version 5.03.635. I get an error 1001 while trying to remove it. I believe I have deleted all of the other dependent applications. I removed the disk encryption and anti theft applications, those are the only ones I could find. Does anyone have any idea what error 1001 means?
