To uninstall MSSE via a script, save the following into a text file, and change the extension to '.vbs':On Error Resume Next Dim objShell Set objShell = WScript.CreateObject ("WScript.shell") objShell.run "'"%ProgramFiles%/Microsoft Security Client/setup.exe"'" & "/x /s" Set objShell = Nothing

Notes: 1. this is for v2 of MSSE - for installations of v1, replace 'client' with 'essentials'. 2. this is for the 32bit version of Windows. 3. the user must have administrative rights on the machine . 4. works fine as a GPO for bulk changes, so long as it is placed under the computer config section (so the permissions above are applied).
