As I mentioned earlier this morning, Microsoft has reissued the botched October SHA-2 patch KB 2949927, posting Security Advisory 3033929 and a patch with the same number. Brian Krebs posted a heads-up shortly after, saying the patch was causing a reboot loop.
Now I see different reports from all over the Web, with a wide variety of problems with the patch.
A TechNet post from Kiran Otter, on Wednesday afternoon, started the wheel rolling:
Security Update for Windows 7 for x64-based Systems (KB3033929)
Installation date: 3/11/2015 8:57 AM
Installation status: Failed
Error details: Code 80004005
I can't find any info on this error. Tried the update twice and both times it failed.
The same TechNet thread now contains details on many other failures, including error codes 800B0100, 80070005, and 80070002. Poster ITJohns on the thread says:
Tried as admin also it has no effect. This is effecting a laptop and two desktops on Windows 7. Security Update for Windows 7 for x64-based Systems (KB3033929) Is causing an infinite loop on one of the machines and the desktop in unreachable completely. The other two are able to back out of it and revert to a previous state. None can install the update.
There's yet another manifestation described in that thread, from Danilo Godec:
- downloads and installs the update
- requests a restart
- before shutting down and restarting, it "Configures Windows" for a while
- after restart, it is "Preparing to configure Windows," gets to about 72 percent, reports "Failure configuring Windows update. Reverting changes"
- restarts automatically
- "prepares to configure Windows" once again, shows the "Failure configuring Windows update. Reverting changes" once again
- shows the login screen
After that, I can try again and all of that will happen again -- even if I try it with the "standalone" file...
A similar thread appears in the Microsoft Answers forum, with this one additional observation from Gene Olson:
I believe I had the exact same problem on the same machine with the previous update KB2949927 mentioned in the KB3033929 advisory last October. In October I found I had to reinstall Windows and all application software on that machine to finally install KB2949927. It gives me no joy to learn from the KB3033929 Advisory that Microsoft has apparently not found the installation problem and chose to release a similar broken update a second time.
The problems have not been acknowledged by Microsoft. There's no Known Issues listing. As best I can tell, the patch is still being offered on Windows 7 machines.
