I can't think of anything more frustrating than a weekend of being unable to update a clean install of Windows via the Windows Update.

In the end I managed to download the patches manually.

It highlights two points for me:
1. It is damn annoying that there is no email address to flame Microsoft,
2. I'd hate to have the same thing happen on a m$ product that required Product Activation after its 50 uses only to find it not working.

Better get in while it works if you haven't!
