If for some reason you want to uninstall the HPC Pack 2008 R2 software from multiple computers, read on...

HPC Pack 2008 R2 is made up of several different components (for example the Client Utilities and the MPI Redistributable) that get installed in different combinations depending on what options you picked during setup. To fully remove the HPC Pack software you must remove all of the components, and some of the components can only be removed in a specific order.

It is not difficult to use the" Add or Remove Programs" or "Programs and Features" control panel to uninstall the pieces from 1 or 2 computers, but if you have a lot of computers to update that can get very tedious.

Copy this script in to notepad and save it as 'UninstallHPC.bat', and you can use it on any computer to remove all HPC Pack 2008 R2, HPC Pack 2008, and Compute Cluster Pack software.

Notes:

  1. This does not remove your database files or any WIMs that you've captured, so you may still have 'HPC-related files' on your computer.
  2. The script needs to be run from an Elevated/Administrator command window or you will have to acknowledge pop-up windows for each step.
