This article describes how to use Package Manager to uninstall a package in Windows Vista.
Note This article also applies to Windows Server 2008.
To uninstall a package, use one of the following methods. Both methods use the Package Manager tool (Pkgmgr.exe).

Method 1: Modify the .xml file for the package
Method 2: Use the command lineAt the command prompt, run the following command:
start /w pkgmgr /up:package_nameNote You cannot use the /up option together with the /m option. The /m option points Package Manager to the folder in which the package is located.
