As a Domain Admin for a small or large corporation, it’s NEVER a good idea to login as the Domain Admin (or other privileged user) to read email or surf the Internet. After all, if you pickup a nasty bug/virus, from Outlook or Internet Explorer your logged in credentials will have the ability to spread the virus to every system in the company… Not a good thing!
That’s where the RunAs command (XP and Server 2003) came in handy over the years. You could login as a non-privileged user but if you needed to do something which required Admin rights, you could hold down Shift and Right Click on the application in Windows Explorer and start the application using your Admin credentials.
With the release of Windows Vista and Server 2008, this all changed. True, you could still use the RunAs.exe from the command line however, if you wanted to do it with Windows Explorer. Fortunately Mark Russinovich has written a new tool called ShellRunAs which adds the RunAs feature to Windows Explorer.
Follow the below Step by Step to get it rolling on your box:
Add Run As Different User to Windows Explorer Context Menu for Vista and Server 2008
1) After you download ShellRunAs from here, copy it to your WindowsSystem32 folder,
2) Open a command line and Run: shellrunas /reg
3) Click OK to confirm Install completed
To test, hold down SHIFT and Right-Click on an application. You should now see the Run as different user in your context menu.
VERY Groovy little tool! Thanks Mark!
