It is very easy to uninstall eg remove the ExperienceIndexOK from you Windows 10/8.1 or other Windows Operating System!
When ExperienceIndexOK running, please close the ExperienceIndexOK and delete the ExperienceIndexOK.exe!
(... see Image-1 Arrow 1 and 2)
PS: But this not improves and not change the Windows Experience Index :-)
