Go to Properties.
is a little easier.
ie. Right click -> Take Ownership
Ownership changes from Administrators to current user.
BTW, it's not recommended you do this on any Windows system folders, (Users, ProgramData, Program Files, Windows, etc), you'll most likely FUBAR the system.....I know, I've done it
I am on Windows7 64bit
Home, Pro, Ultimate, Enterprise?
Single user system?
Multi-user with only one admin, (you) ?
