The runas command

Could be used for running software with different credentials.

C:\Windows\System32\runas.exe /?

RUNAS USAGE:

RUNAS [ [/noprofile | /profile] [/env] [/savecred | /netonly] ]
        /user:<UserName> program

RUNAS [ [/noprofile | /profile] [/env] [/savecred] ]
        /smartcard [/user:<UserName>] program

RUNAS /trustlevel:<TrustLevel> program

   /noprofile        specifies that the user's profile should not be loaded.
                     This causes the application to load more quickly, but
                     can cause some applications to malfunction.
   /profile          specifies that the user's profile should be loaded.
                     This is the default.
   /env              to use current environment instead of user's.
   /netonly          use if the credentials specified are for remote
                     access only.
   /savecred         to use credentials previously saved by the user.
   /smartcard        use if the credentials are to be supplied from a
                     smartcard.
   /user             <UserName> should be in form [email protected] or DOMAIN\USER
   /showtrustlevels  displays the trust levels that can be used as arguments
                     to /trustlevel.
   /trustlevel       <Level> should be one of levels enumerated
                     in /showtrustlevels.
   program         command line for EXE.  See below for examples

Examples:
> runas /noprofile /user:mymachine\administrator cmd
> runas /profile /env /user:mydomain\admin "mmc %windir%\system32\dsa.msc"
> runas /env /user:[email protected] "notepad \"my file.txt\""

NOTE:  Enter user's password only when prompted.
NOTE:  /profile is not compatible with /netonly.
NOTE:  /savecred is not compatible with /smartcard.

Example for running a program as another user (e.g. admin from a normal user account):

C:\Windows\System32\runas.exe /user:localhost\username /savecred "C:\foo\bar.exe"

Putting this in a shortcut will start the program with that user's rights, saving or using previously saved credentials.
