Were you running a previous version of Win10 with WMC installed, and then Win10 upgraded and you had to install WMC again?
WMC Version 8.8.1 has the best uninstaller.
Sometimes previous versions don't clean 100%
Which WMC version are you using? v6, v7, v8, v10, v11, v12, v8.8.1
Have you asked this question in the place where WMC for Win10 was created?https://forums.mydigitallife.info/threa ... ost1026727
