Look for all programs containing a search string, and uninstall it.

Uninstall-Universal.ps1

<#

.SYNOPSIS
Looks for installed applications with a search string to be found in either its
name or the publisher name and uninstalls them.

.DESCRIPTION
It takes a search string (-SearchString) that it uses to look through the names
and publishers for the search string, and uninstalls them.

This was primarily made to be used with SCCM.

.PARAMETER SearchString
Mandatory: Yes

Aliases: p, Publisher

This is the string the script will use to search through the list of applications
in both their names and the publisher name.  This is case insensitive.

.PARAMETER Silent
Mandatory: No

Aliases: s

Suppress progress output, and a dialog box signifying completion.

.EXAMPLE
Uninstall-Universal.ps1 "java" -s

Look for Java to uninstall silently.

.NOTES
At the moment, it only works with packages installed using an MSI installer.  It
has not been tested with other installers, like InstallShield.

Known issue: this currently only works using msiexec to uninstall things
   - has not been tested with other install programs (e.g. InstallShield)
