Install MSU files with PowerShell

I have been working with fixing som stuff with IE 11 installation with SCCM in a OSD TS.

My solution to install some needed KB files was to fix a PowerShell script that will look in the folder \source\ and x86 for x86 computers and x64 for x64 computers for all .msu files.

Then take the KB name and check if the KB is installed or not.

The x86 folder:

If the KB is not installed the script will install it.

And log everything to a log file.

I use c:\windows\temp as log folder because it did work best for me during the installation.

This script will work to install all .msu files not just for IE 11.
But the script is just designed for one OS.

Thanks to Micke (“The Deployment Bunny“) for haveing a nice blog with lots of nice stuff.
This script has some influences from his scripts.
