Uninstall doesn't restore context menu

[medo64]

If you install your program (tested versions 4.11 and 4.21) and then delete it, then the utilities "Simple VHD Manager" and "VHD For Context Menu" (Sordum - http://www.sordum.org/ ) do not want to add their commands to the context menu. In the "Send to" menu - they add, but they are not added in the file menu, although the opposite is displayed in their settings. However, if you return to the previous state of the system before installing the VHD Attach, everything works fine. Probably, VHD Attach leaves some mark on the system, blocking some functions of the Simple VHD Manager and the VHD For Context Menu.

Or these programs are incompatible. How can this be fixed?
