Problem is, you can't delete the mutable back up without SYSTEM permissions. so you have to go through a long ass process of making yourself become the proclaimed owner of that folder. to do this find the windowsapp folder. click permissions go to security go to advanced at the top you will see a thing that says owner. click on that enter your admin password and use your username for your workstation. when thats done you will now be allowed access into your windowsappdata folder. inside you want ot find mutable backup you want to click that folder do what you did as you did before make yourself the ownwer of that folder. don't delete the mutable folder but go in finde the other two files make yourself the owner of those go in agian make yourself the owner of the data and game guard then delete them. done.
