Get uninstall strings from windows registry

get-uninstallstrings.ps1

# some apps will not show up in the wmi win32_product object, but there is a way to get the uninstall string for everything
# this will troll the registry and show those apps. Note that the uninstall strings listed will likly not be silent or unattended
# so you may need to do your own research on how to do that
