On Windows 7, you'll need to enable the hidden "administrator" login using the instructions below.. For most, that's a good thing.. It's better to have TWO different user accounts which have admin rights...just in case one goes south. After you enable the hidden administrator login, it's a good idea to create a password for it, and make sure you write it down or remember the password somehow.. You may not use it much, but when needed, you'll want that passworded "administrator" login.
Click on Start, then type: "cmd" in the Search line (without the quotes), then RIGHT click on "cmd.exe" at the top of the search page, choose "Run as administrator".
At the command prompt, type: Net user administrator /active:yes
Press the "Enter" key..
An unpassworded Administrator account will now show up on the Welcome screen.
To disable it: Open the command window again, and type: Net user administrator /active:no
Press the "Enter" key.
Alternatively you can also enable or disable the administrator account from the Local Policy if you've got the PRO version of Windows 7. Click on the start menu and type secpol.msc in the search bar and click enter. This opens the Local Security Policy. Navigate to Local Policies-> Security Options and here you can see an entry Accounts: Administrator account. Double click the entry to enable or disable.
Or, possibly...open the Control Panel, double click on "Administrative Tools", then "Computer Management", then "Local Users and Groups" on the left side of the screen, then the "Users" folder.. Once there, RIGHT click on the "Administrator" listing in the middle of the screen, select "Properties", then UNCHECK the "Account is Disabled" box. Click on "Apply", then OK
Hope this helps.
When I set up my Windows 7 computer, I set up my login account as Administrator account type, username Mercury. Recently downloaded and installed a number of programs and put shortcuts to them on my desktop. One of these programs won't let me open it, demanding that I be logged in as Administrator. Two other programs won't let me simplify (rename) the name assigned on the shortcut icon (on desktop), also demanding that I be logged in as Administrator. I'm already logged in as Administrator (Mercury). In loggin account management, if I try to change username Mercury to username Administrator, this is disallowed, under the message that username Administrator already exists, which is untrue. What am I to do to make the computer see me (Mercury) as Administrator account type or to change username to Administrator? Thank you!
