It bricks Windows 7 on AMD Athlon X2 as well
Yup, it showed up on my PC tonight, before Patch Tuesday, and a family member saw it and applied it dutifully, just like I told them they should always do. The Windows automatic startup repair would not work. I could use one of its options to rollback to the Restore Point it created before it installed and all is well now. And Check For Updates is now turned off.
This was an HP desktop. My Compaq desktop also has an AMD processor so I removed its power cord for now. Both are 10+ years old and started out on Vista but are running perfectly for the limited use they see.
