Wow, there is a disconnect between Microsoft and end users.

Even if users experience PC trouble after installing the patch, they will still be protected against any attack exploiting the Windows flaw, a Microsoft representative said.

But but but

The patch could lock users out of their PC, prevent the Windows Firewall from starting, block certain applications from running or installing, and empty the network connections folder, among other things, the software maker said.
(Bold added by me.)

Maybe this is just me, but I could really care less if my computer is protected from some computer worm if I cannot get into my computer! If the program I need (yes, need, not want) to use will not start, then the computer is broken.

I don’t consider this rocket science.
