As of this writing (Tuesday Feb 16th) there don't seem to be any new suggestions from Microsoft to assist XP users whose systems were rendered un-bootable after installing the February 9th patches. For example, the last entry on The Microsoft Security Response Center blog is four days old. So let me offer a suggestion: boot to Linux and move some files around. Windows Update on XP is architected [sic] to allow for the backing out of patches. The problem is that this depends on the system being bootable, so it's of no use when even Safe Mode is unavailable, as is the case here. And, as I wrote last time, the official troubleshooting tool from Microsoft, the Recovery Console, is unusable for many, if not most, Windows XP users.
