Good Morning,

A windows update seems to have hosed two of my laptops, same make/model. Dell Latitude E7470. I just installed windows and was doing updates, I rebooted for what I believe was the last batch up updates and now both are blue screening with 0x6F.

Full Error:


Technical Information

Stop: 0X6F (0XFFFFFFFFC000012F)

Things I've tried:

  • Startup repair
  • System Restore
  • Copying the regback files back to the config folder
  • check disk
  • SFC /scannow /offbootdir=c:\ /offwindir=c:\windows
  • MacriumReflects BootFix
  • EasyRe Automated Repair
  • LastKnownGood Config
  • Safemode

Nothing seems to make them boot back up. Any ideas?

  • Bug Check 0x6F = SESSION3_INITIALIZATION_FAILED: msdn.microsoft.com/en-us/library/ff559156.aspx can you share the dmp files are post the value from te 1st parameter? – magicandre1981 Feb 20 '17 at 16:06
  • Thats the other thing I forgot to mention that is strange. It's not creating a dmp file. It's as though a dump never happened, the minidump folder was never even created after the dump. Give me a sec and i'll post the parameter – Ryan Feb 20 '17 at 16:08

  • STATUS_INVALID_IMAGE_NOT_MZ so a DLL/Exe/SYS is not a valid windows file. if sfc can't fix it, restore a backup – magicandre1981 Feb 20 '17 at 16:26

Got it back up and running. once it was decrypted from Dells DDP Encryption, I was able to go into the winsxs folder and rename the pending.xml file to pending.old and then because a reboot was no longer pending for the update that was failing it allowed me to run sfc /scannow /offbootdir=c:\ /offwindir=c:\windows which found corrupt system files and then when I rebooted it came back up.

    ok, I added Dell DDP Encryption, so that other can find it easier. not everyone reads all comments. – magicandre1981 Feb 25 '17 at 6:28
