As some of you may know, WMF v4 is not deployed on wsus-servers because of compatibility issues with some older Microsoft Products like Exchange and Lync. However it's often necessary to upgrade the Powershell version for some deployment soutines to work properly.
This script will
1. check for install file
2. check if it's installed from before in registry and then finally
3. install the update.
It expects the file Windows6.1-KB2819745-x64-MultiPkg.msu to reside in the folder {PackageShare}wmf\wmf4\.Else you may have to modify these values. It will fail for x86 windows, since that's another package. But who runs x86 anymore? 🙂
