Open Windows explorer> tools> folder options> 'view' tab> scroll all the way to the bottom and untick 'use simple file sharing.' After that, right click on the folder> properties> 'security' tab> 'advanced' button> 'owner' tab. Try changing 'ownership' and see what you see.
If that doesn't work, back up the affected folder and then restore it to an alternate location w/o the security features.
