How to Add a User to the Administrators Group

In today’s easy Ask the Admin, I’ll show you how to add or remove a user account from the local Administrators group in Windows 7 and later operating systems.

Sometimes it’s not enough to elevate privileges in Windows, and there’s no option but to add an account to the local Administrators group. In this article, I’ll show you how to use the Local Users and Groups MMC snap-in to modify group membership in Windows.

Start a management console with administrator privileges

The instructions below assume that you are currently logged in with a standard user account. If you’re already logged in as an administrator, you can skip elevating privileges when starting the management console.

• Type mmc in the Cortana Ask me anything box by the Start menu, right click mmc in the search results, and select Run as administrator from the menu.
• Now enter the credentials for an administrator account in the UAC dialog.

In Windows 7 Professional, Enterprise, and Ultimate, you can start a management console in the same way by typing mmc into the search box on the Start menu. In Windows 8, go to the Start screen, type mmc, and right click the entry in the results panel.

Add the Local Users and Groups snap-in

Now we need to add the Local Users and Groups snap-in to the console:

• In the MMC window, click CTRL+M.
• In the Add or Remove Snap-Ins window, double click Local Users and Computers under available snap-ins.
• In the Choose Target Machine dialog, make sure that Local computer is selected, and click Finish.
• In the Add or Remove Snap-Ins window, click OK.
• In the console window, expand Local Users and Computers (Local), and then click Groups.
• In the right pane, double click Administrators.
