Automate PowerCLI Install using Powershell

I had a requirement to automate PowerCLI installation with minimal manual involvement possible

I found the syntax mentioned below from Here

Prerequisites


Download and Copy the executable to shared location
Ensure the access is configured

Install PowerCLI Syntax


Set-executionPolicy RemoteSigned -Confirm:$false -force
Write-Host "Installing PowerCLI"
$myargs = $myargs = '/q /s /w /L1033 /v" /qn '
$exe = "C:\PowerCLI\VMware-PowerCLI-5.5.0-1931983.exe"
Start-process $exe $myargs –Wait
Add-PSSnapin -Name VMware.VimAutomation.Core

Optional


I also wanted to try to make it completely automated using Powershell DSC  as mentioned Here however I still haven’t had chance. Posting It here in case anyone wants utilize the same

Microsoft Convenience Update and VMware VMXNet3 Incompatibilities KB Article Updated

Earlier I shared the incompatibilities with VMXNet3 - bit.ly/1sQhHVi

Looks like Microsoft KB was updated yesterday with a work around for the same

Known issue 1

Symptoms


A new Ethernet vNIC may be created with default settings in place of the previously existing vNIC, causing network issues. Any custom settings on the previous vNIC are still persisted in the registry but unused.

Resolution


To fix this issue, run the VBS script that's provided below. Copy and paste this in notepad and save with .vbs extension.

Instructions


This script can be run on physical or virtual computers:
Immediately prior to installing the Convenience Rollup.
Or
Immediately after installing the Convenience Rollup but prior to restarting the following patch install.
Or
After installing Convenience Rollup 3125574 and restarting even though the computer is in problem state. In this case, another restart will be required after executing the script.
