Here's a nice little recipe to uninstall programs on a Windows machine from the command line:

• Open cmd.exe as administrator
• Run WMIC.EXE

• Type the following at the wmic:rootcli> prompt:

  product where "name like 'foo%'" call uninstall /nointeractive /norestart

Replace foo with a string to search for at the beginning of the program name. To get a list of program names, type "product get name".
