Microsoft Windows 7

Normally you can change ownership on a folder through the admin group account...yours. Sometimes, however, Windows will balk. At this point it's usually time to break out the big guns...the hidden administrator account.

You activate this account through the command prompt.

1. Click the windows orb and type cmd in the search block.
2. Right click the cmd.exe above the search block and run as administrator.
3. In the command window type net user administrator /active:yes
4. Switch users (log onto the administrator account)
5. Make your ownership changes...if you want to change ownership to this account, complete your deletion here as well.
6. log off the administrator account and switch back into your normal account.
7. If you didn't log off, the command window is still active (if you did log off, reopen the command prompt as administrator)
8. in the command window type net user administrator /active:no*
9. Exit the command prompt

* If you would like to keep the administrator account active (not recommended, but your choice) you don't need to disabe, but you should include a strong password. This can be done in the command prompt or through the control panel user accounts section. If you forget the password you can always change it with your regular admin account.

Few Shortcut to do the same above Steps:

1. type cmd in the search block.
2. CTRL+SHIFT+ENTER.
3. ALT+Y on pop up to open command prompt in Administrator Mode.
