There’s no official confirmation, and no explanation of course, but overnight Microsoft pulled a patch that was supposed to fix the main problems in this month’s Windows 7 security updates. I talked about the repair hotfix yesterday in "Microsoft repairs buggy Win7 security patch with buggy hotfix KB 4039884." Today, the repair hotfix isn’t available anymore.
All we know for sure is that sometime last night, the Microsoft Update Catalog entry for KB 4039884 disappeared. As of early Tuesday morning, Eastern time, the KB article is still available, and it hasn’t been modified — it still points to the Update Catalog.
