NOTE: I had an argument with Microsoft. They thought they owned my computer, I thought I did. Microsoft won by cheating, they clobbered my sys admin settings. Microsoft won the battle, but lost the war. If I can't trust a company to do an update, how can I trust it at all? All future updates of Windows-only software will no longer be listed here.
