Works good
I couldn't properly uninstall Autodesk Maya 2016 for a long time due to compatibility issues, but after installing this utility, it did everything on its own in a very short time. Therefore, 10/10!!!
It's great that this wonderful tool exists, as there are programs that can be resistant to being uninstalled. Congratulations.
I tried, but it doesn't work for me when applying it to W7. Or is there another program to uninstall Windows Live?
