By default, the Windows 7 Administrator user is disabled. This prevents you from doing interesting things like using the RUNAS command to start shells with extra permissions.
To enable the Administrator user, do the following:
- Open the Explorer
- Navigate to C:\Windows\System32 and select cmd
- Right-click and select “Run as Administrator”
- Give permission to make changes to your system. This will open an elevated permission command prompt.
- In the elevated permission command prompt, enter “net user Administrator /active:yes”
- Go to Control Panel -> User Accounts and Family Safety -> User Accounts -> Manage Another Account
- Select Administrator
- Create a Password (or Change the Password if you’ve already set one).
- Enter the password twice to set/change it
It’s probably wise to have a fairly strong password on the Administrator account.
