Windows Update 3033929 Causing Reboot Loop

Windows Patch

One of the operating system updates Microsoft released on Tuesday of this week — KB3033929 — is causing a reboot loop for a fair number of Windows 7 users, according to postings on multiple help forums. The update in question does not appear to address a pressing security vulnerability, so users who have not yet installed it should probably delay doing so until Microsoft straightens things out.

Various tech help forums ares starting to fill up with requests from Windows 7 users who are experiencing a reboot loop after applying the glitchy patch, which is a “code signing” update that improves the ability of Windows 7 and Windows Server 2008 R2 systems to validate the integrity and authenticity of programs running on top of the operating system.

At this time, none of the tech help forums seem to have a solution for the problem. If that changes (or if Microsoft pulls and re-issues this patch) I’ll update this post with a solution. For now, it’s best for Windows users to delay installing KB3033929.

    So if it was installed automatically should I uninstall it?

    • xper

      You can try this. Sometimes it help, sometimes not.

      1. Open a Command Prompt (Run as Administrator).
      2. Type: cd %windir% and press enter.
      3. Type: net stop wuauserv and press enter.
      4. Type: ren softewaredistribution softwaredistribution.old and press enter.
      5. Type: net start wuauserv and press enter.
      6. Type: Exit and press enter.
      7. Try installing the updates once again.

      Most of the issues are with customized bootloader, dual boot system or inactive partition.

      Rvnlord suggests the following to fix the issue on computers without a dual boot (grub):

      1. Open directory where is the file mentioned in the error, in my case: “C:WindowsWinSxSamd64_microsoft-windows-b..vironment-os-loader_31bf3856ad364e35_6.1.7601.18741_none_b9293c0383618646winresume.exe”
      2. Right Click on the file > Properties > Security > Advanced > Owner > (Set it to your Account) > OK
      3. In previous Window: Edit > Add
      4. You need to add two accounts
      – “SYSTEM”
      – “NT SERVICETrustedInstaller”
      5. Give them both Read, Write, Execute permissions. > OK
      6. Now KB3033929 which is one big nightmare should install without any problems and ask you to restart your computer afterwards.

    xper – Thanks but all that was way over my head. I’m not a techie by any stretch, just an old guy who likes to press the “On” button and have things work perfectly. I checked my Windows updates and saw that 3033929 was installed yesterday. If I select it and right click I have an “Uninstall” option. Will this “Uninstall” get rid of this update so that I can turn my pc off tonight and not worry about this endless loop thingy when I turn it on again tomorrow? Or is that too simple a solution? Thanks.

    Bob if it was already successfully installed, it is OK, don’t uninstall.
    I had problems too, because of grub taking care of bootloaders.
    stupid microsoft… I have never experienced something like this in other operating systems…
    in win 10 TP you should disconnect other drives, that’s incredible!
    wake up, M$!

      From technet.microsoft.com:

      “I disabled GRUB2, so that Windows loaded automatically and now the update succeeded…

      I’m not 100% sure all of these steps are necessary, but here’s what I’ve done:

      – boot Linux and set the ‘active’ flag for Windows partition (at that point I left the ‘active’ flag on my Linux partition as well)
      – GRUB2 menu still loaded first
      – boot Windows in ‘Repair your computer mode’ and run ‘bootrec /fixmbr’
      – GRUB2 menu still loaded first, but I tried to boot Windows to install the update, but it failed in exactly the same way as before
      – boot Linux again and turn the ‘active’ flag on the Linux partition off
      – now Windows boot’s directly without GRUB menu
      – KB3033929 update installs successfully

      After that I booted Linux from a CD drive, changed the active flag back to Linux boot partition and I got my dual-boot back.”

      • intzepatorii

        No, it’s OK I’ve already solved it…
        I disconnected the drive having the Linux /boot partition, recovered the 200 MB partition in only 2 minutes and it was sufficient.
        Thanks anyway.
        I still don’t understand how Ms can issue updates without testing more environments and also after people jumping at them with claims they don’t recall the respective update from the pool.

    intzepatorii – Thank you

    This is interesting how many changes and updates microsoft bring out. Its safe to say the administartion is shared to the extent of the person creating the file or shares. There are many topics on musicianal things that we all can relate and vibe too. There comes a time when we need to feel whats there when the software is updated. Who knows if its real but at the end of the day you know what you made of it to restore yourself to being the person you are normally and doing things to change the oppinion on the haterz 😛 Fuck all i can say is i like feeling instrumental it brings another side out to me that i cant explain i dont know about you guys but im sure you have fealt the egger to do something with one of your loved ones so dont be mad respect all the way i completly understand for your own ammusement all good thoe man i luv this shit (August)
