Launch your web browser as a different user

I often need to sign into SharePoint or another local server as a different user. An easy way to do this without logging out of your computer is to use the 'runas.exe' command. open a command prompt and enter the following command:

runas.exe /u:domain\username "C:\Program Files\Internet Explorer\iexplore.exe"

substitute domain\username with your account you want to login in with, I use a test account made specifically for these situations.
