Sitecore and Sitecore Commerce 9.2 Instance Uninstall PS Script

Based on https://naveed-ahmad.com/2018/02/23/sitecore-experience-commerce-xc9-the-uninstall-script/ but, uninstalls  Vanilla Sitecore instance too apart from Commerce instance.

Copy over the below script and save to name you wish with ps1 extension. Run from Powershell. Just modify params based on what is passed in install script. This uninstalls both Vanilla Sitecore and Commerce Instance including websites, app pools, solr core folders, DBs and windows services. It doesn't delete folders from the following locations:

c:\users
c:\certificates

Copy from below this line (replace param values based on install script):
