    This is a small gist with snippits I frequently use in PSADT - PowerShell App Deployment Toolkit.
I've also stole a few from here to get started, I've populated a bunch I use regularly.
Be careful with the scripters inc link above^^ however, all of the quotes are funky UTF-8 and don't paste into a terminal without errors (all the quotes in this gist have been checked).
Also, additional note that isn't strictly related to PSADT, but is helpful in deployment matters.. I've included an example_app.exe.manifest file. From what I can see, when you come across a legacy app that requests administrator privilige on launch (but does not have 'run as administrator' checked in it's properties, you can overrule this behaviour by creating .exe.manifest file (named in accordance with the .exe's file name), with the following within the file:
<requestedExecutionLevel level="asInvoker" uiAccess="false"/>

As opposed to:
<requestedExecutionLevel level="requireAdministrator" uiAccess="false"/>

See example in this repo, or read more here and here

c:\program files\vendor
using the above example, it will only remove c:\program files\vendor if every other folder above is completely empty.
if for example v11 was also installed, it would stop prior #>
