Lose OS when running .bat file
Purging and Re-installing
https://forums.stardock.com/486022/start10-support-faq#reinstallingUnder a previous post, Purging and Re-installing, if you're having trouble getting the app to work, the following file is to be downloaded and run as administrator: http://sd.stardock.com/zubaz/apps/Purge_StartALL.bat. So, I did this, and, lo and behold, no more WIN10 on my VM Paralells. Had to restore a Snapshot to get my OS back. Something definitely wrong here. So, why not use Window's deinstallation instead?
This is for Sean Drohan's attention.
