VMware: Install PowerCLI

KB ID 0001606 Problem There was a time you had to go to VMware and download PowerCLI then install it, that’s no longer the case, any machine with a, (reasonably new) version of PowerShell can simply pull the commandlets down from a repository and you are ready to go. Solution Firstly if you have the ‘old version’ of PowerCLI you can uninstall it from Add/Remove programs (appwiz.exe). Before installing, you need to be...
