STOP 0x0000C1F5 / 0xC1F5 / C1F5 Revisited

Posted by: Tom Karpowitz in Vista on  


It has been almost a year and a half since I first experienced a STOP 0x0000C1F5 on Vista and discovered a workaround for the problem (see my original post on the topic here).  Since that time, I have received tens of thousands of page hits, hundreds of comments, countless side conversations, and even a few donations as a result.

 

Several people contacted me to inform me that there is FINALLY a fix available from Microsoft for this problem.  It seems that the Windows 7 beta disc (and, of course, the Windows 7 RTM disc) includes a “silent fix” for this issue.  Apparently, when you boot a Windows 7 disc and it is identifying potential partitions for installation, it silently fixes any problems with $TxfLog that it finds… so if you boot it to the “Install Now” prompt, abort the installation, remove the disc, and simply boot Vista off your hard drive, it should fix itself.  This is described in KB970101.

 

I have personally not tried this approach because, thankfully, I don't have any systems that are experiencing the STOP code.  But if you are, and you happen to have access to a Windows 7 disc, you might want to try it... and please post your results here.  If you don't have a Windows 7 disc, by all means try my original fix.

 

I think it’s interesting that Microsoft  (1) never really acknowledged the breadth and impact of this problem, (2) never came up with a workaround until now, (3) never mentioned that there were ANY workarounds until now, and (4) didn’t give me any credit.  Well, actually (4) doesn’t surprise me at all.

  • Steve  - Using Windows 7 Disk Worked.
    I have a client that encountered this error. I downloaded a Windows 7 Pro disk. Burned it and started it in the PC. I went all the way there to where it asks me to Upgrade or Custom and I turned it off and took out the disk.
    When Vista started back up it loaded the Startup Repair tool and ran for a couple mins. Then it started right up no problems at all.

    Sad they can't just create a actual fix without having to download or purchase windows 7 to fix a Vista problem.

    Microsoft, what will they screw up next.
  • Sean- Followed same steps as S
    Used a Windows 7 beta disk got to the upgrade section shut down computer and Vista booted.
  • Anonymous  - Thank you... you are the best... !!!
    Thank you... you are the best... !!!


    With WIndows 7 is the easyest way...

    Like you said... after restarting ... choosing "Start normal" and then you see, how this Fix will be unpacked and updated ...

    Thanks...
  • Tore Jacobsen  - Worked great
    Thank you mucho!!
    Downloaded a Windows 7 ultimate (piratebay)
    Burned and booted on it.
    Went to the "install now" screen an canceled.
    Booted and had the chose of Normal and something like "boot repair". Went with boot repair, took aprox 10 min. And after that Vista booted like normal. :P

  • Mea  - =(
    7 isnt avaible anymore in RC ... :(
    What do I do?
  • Steve
    Your right Windows 7 RC isn't available anymore through Microsoft.

    If you are familiar with torrent sites you can get a release disk from them. I used The Pirate Bay for my download as did Tore.

    Don't worry about copyright or legalities because your not downloading the disc to steal Windows 7, your only downloading it to fix a flaw in a program.
  • Jake  - Need some help...
    If I just go out and buy Windows 7, should this fix work? I am not familiar with what "RC" means. Do I need a beta or RTM version, or would a current commercial version on Windows 7 work?

    I figure I can go buy WIndows 7 from Best Buy, do this fix, and then return the disk.

    Thanks.
  • Tom Karpowitz
    @Jake: "RC" = "Release Candidate". It's the development stage between "beta" and "RTM" ("Release to Manufacturing", the final release which is actually being mass produced and sold).

    *Any* build of Windows 7 >= beta will work, including the RTM version that you can buy at Best Buy. How you get your hands on a Windows 7 disc is up to you... :D
  • Henrik  - Thanks
    Booting from Windows 7 RTM Disc Worked.

    I had this problem on HP Desktop with Windows Vista, and wasn’t able to book normally, safe-mode, or even start System restore from the original recovery discs.

    I tried to boot on Windows 7 RTM and aborted the installation when Installation screen showed with the “Select language”, and afterwards I were able to boot the computer from the original System restore discs. I didn’t try to boot normally, because I wanted to reinstall it anyway, but my guess it would have worked too.
  • Angeline  - Cheers!!
    I tried that with the windows 7 disc and it worked perfectly!! :D
    So much easier than messing with the hot fix microsoft suggested...I think they need to add you to their team
  • Pamela  - Wonderful Windows 7
    Hurrah!!! Windows 7 Ultimate worked in 5 mins. Thank you so much for the tip, there's hope for technophobes everywhere with people like you to help!
  • Ethan  - awesome work
    Great and simple fix. I'm glad I found your site before I tried a bunch of things I now know would not have worked. Thanks dude.
  • Will  - Persistence pays off....
    Yea! It worked - I happened to pick up an RC theother day knowing full well that it wouldn't really be WIN7 for me - but I've now found a fix for the dreaded 0x0000C1F5 error. In my instance I loaded to the point of install then backed out. I tried the startup repair but just got the same 0x0000C1F5 failure. I finally just let it start by itself - it worked. Back into VISTA! Why am I happy about that? Anyway - getting WIN7 for my own system now. Thanks for your help.
  • Adam  - It Works!
    Thanks for the great info on this. The process worked very well with the Windows 7 disk!
  • AJ  - Windows 7 solution worked
    Just wanted to thank you for the help. I tried the linux solution and it didnt work for me (deleted the file but still got the same error whenever I tried to reinstall the OS via recovery drive or CD/DVD). When I did the Windows 7 it worked perfectly! Thanks again for the help!!
  • DP
    Don't know, tried both "solutions" with no success!!!! Guess I will have to reformat the hdd, this really sucks out loud!!!!
  • Sandman  - Perfect! Fix does work
    Tried your fix suggestion for this error. It worked like a charm. I used a retail version of Win7. All you have to do is just insert the DVD and it will fix the log file ($TxfLog). At the first prompt screen just close it and it will restart your PC or Laptop. That's it and it is that simple good luck to everyone. Thanks a million.
  • DP  - No Work Here
    I am glad this worked for all of you but it did not work for me at all!
    I am now in the process of reformatting my hard drive and installing windows 7, maybe I should go back to XP???
  • john
    thankyou it works fine that realy helps,window 7 the way forward.
  • Paul Clarke  - Thanks
    BRILLIANT - This might just have been the single most usefull fix I have seen for ages.

    Now a certain university student will be happy that her laptop is fixed.

  • mattyo  - all i have to say is.....wow
    IT worked :D reinstalling Vista as I type. I installed
    linux and ran the Diagnostics tools then did this fix :P
    ps ... your the best
