# -----------------------------------------------------------------------
# Prerequisite:
# Should work with both PowerShell v1 and v2. I wrote and tested it on XP
# as well was Windows 7 x64. Make sure to have your execution mode is set
# properly. PSH> get-help about_Execution_Policies
# In addition, WASP, Windows Automation Snapin for PowerShell, was used
# for the macros to run and click items as needed, it is not mandatory.
# -----------------------------------------------------------------------
# 2010.03.15 ver 1.2
#
# Summary:
# Removes software based on display name shown in "Add Remove Programs".
# In the majority of cases it just runs whatever uninstall program the
# program claims will uninstall itself. In a few cases a macro is run.
# See $apps array section and comments to add to the list of programs.
#
# Known Bugs:
# At this time I have noticed an issue with the "Bing Bar" attemping to
# re-install itself. Actually what is happening is a related install
# 'Bing Bar Platform' is being launched and as a result it asks if you
# want to reinstall. I haven't looked into solving this just yet. My advice
# at the moment is... don't reinstall it. *laugh*
