Windows Update KB2847927 won't install

From an elevated command prompt (administrative command window) run:

"sfc /scannow" (without quotes).  Restart. And try again.

First make sure virtualization setting is enabled in bios ...then try installing virtual pc

https://www.grc.com/files/securable.exe
Run the above tool to find out whether virtualization setting is enabled

tried sfc /scannow early on, gets to 59% and bombs out, sfc /verifyonly runs all the way through though, and returns a message about integrity violations

Ran the securable.exe, results were 64, Yes, Yes

Download and run system readiness tool

After running this tool ...reboot and then try installing virtual pc.

KB2847927.jpg

It appears that Windows Virtual PC installs, but then when I restart, it gets to 100% of installing Windows updates, then "Failure configuring Windows Updates. Reverting changes" and undoes everything

Download and run system readiness tool

http://www.microsoft.com/en-in/download/details.aspx?id=20858


After running this tool ..Uninstall your security software (Antivirus).reboot and then try installing virtual pc.

I think I've already tried the system readiness tool, but stand by, will download and run.,

If the issue persist after system readiness tool upload checksur.log here for analysis


C:Windows\Logs\CBS\checksur.log




Ded9

If Microsoft Security Essentials is the only anti-virus software installed and running, do I need to uninstalled it as per your instructions?

No do not uninstall mse


Ded9

the .msu for the readiness tool took forever to download, then it ran a "hotfix" but I never did see the a "readiness tool" dialogue box.  Where did it go?  I had to leave that location and won't be back there until Friday of this week, will update you then.

You just need to install the system readiness tool hotfix ...restart and then try updates.



Ded9

hotfix seemed to install, restarted, no change, here's that log
CheckSUR.log

Not sure if this is related (probably), but sfc /scannow stops at 59% every time, see attached
sfc-error.png

I'm about to try this: http://www.sevenforums.com/tutorials/3413-repair-install.html but had hoped to avoid that if there was some other workaround, seeems like I'm close to a resolution.

Sorry. Looks like you have reached an unavoidable conclusion.  Please go ahead with it.

Looks like o.s files are corrupted.

 You can do a repair install and make sure you run a chkdsk on C drive....this will check for any hard drive related issue.



Ded9

had tried chkdsk previously, found no problems
trying everything I can to avoid the repair install
I think I've tried every windows update fix tool, no changes

Run mga diag..upload results here...to check whether the problem is with the product key.

http://go.microsoft.com/fwlink/?linkid=52012

Rename cbs.log ...run sfc /scannow ...after you get the error zip cbs.log and upload it

%windir%\logs\cbs\cbs.log



Ded9

gonna run the mga diag, and will upload those logs, stand by
in the meantime, I found the original Dell Reinstallation DVD, is there an option to reinstall from that, or only a clean install?

as requested, please advise
MGADIag-results.txt

as requested, cbs.log immediately after sfc /scannow fail, errors out at 59% every time
CBS.log

Problem is with the key  as per mga diag report.

so far so good, but not sure what you mean by "addon" on genuine website, can't find it

isn't that just for Windows XP? (Windows Genuine Advantage Validation Tool), this is Windows 7

Well, I thought you were on to something that time, but no luck, same error trying to install that one update in Windows Update.  Darn.

Dell Reinstallation DVD did the trick (in upgrade mode).  All Windows Update errors resolved, was able to install Windows Virtual PC and Windows XP Mode.  Problem solved, thanks!

ok... I suffered the exact same issue (KB2847927 won't install) and got to the bottom of it... A repair install is NOT required though it will fix the issue (with a big hammer).

Short answer:
The machine is infected with ZeroAccess and can be repaired with this tool:
http://kb.eset.com/esetkb/index?page=content&id=SOLN2895&locale=en_US

More Details:
The cbs.log indicates that essential Windows Defender / MSE files have been corrupted. As seen by the following line showing that MpEvMsg.dll has been turned into a symbolic link and its permissions removed:

2013-07-23 09:19:50, Error                 CSI    000001c8 (F) STATUS_FILE_IS_A_DIRECTORY #4167560# from Windows::Rtl::SystemImplementation::DirectFileSystemProvider::SysCreateFile(flags = (AllowFileNotFound|AllowSharingViolation|AllowAccessDenied), handle = {provider=NULL, handle=0}, da = (SYNCHRONIZE|FILE_READ_ATTRIBUTES|FILE_READ_DATA), oa = @0x42cfc0->OBJECT_ATTRIBUTES {s:48; rd:NULL; on:[131]"\SystemRoot\WinSxS\amd64_security-malware-windows-defender-events_31bf3856ad364e35_6.1.7600.16385_none_118cf1dcd54a3dea\MpEvMsg.dll"; a:(OBJ_CASE_INSENSITIVE)}, iosb = @0x42d070, as = (null), fa = 0, sa = (FILE_SHARE_READ|FILE_SHARE_WRITE|FILE_SHARE_DELETE), cd = FILE_OPEN, co = (FILE_NON_DIRECTORY_FILE|FILE_SYNCHRONOUS_IO_NONALERT), eab = NULL, eal = 0, disp = Invalid)

Select allOpen in new window

The update KB284792 is attempting to service windows defender files and therefore fails with the access denied error code.

This thread also discusses this same issue:
http://www.sevenforums.com/system-security/290614-sfc-warning.html

Will make a note of that for future reference (I already used by "big hammer").
Thanks!
