Filtering the details
Running the sfc /scannow
will produce a CBS.log
report file (usually found in C:\Windows\Logs\CBS
) which contains a wealth of information. In order to get the juicy bits, open a command prompt, and execute this command:
findstr /i /c:"[SR]" "%windir%\Logs\CBS\CBS.log" | findstr /i /v /c:"verify" > "%userprofile%\Desktop\sfc.txt"
The above command will:
Get all lines in the original file containing [SR]
, which are the ones that track the repair attempts.
Remove all lines containing verify
from what we got in the previous step in order to further reduce the clutter.
Write the results in the sfc.txt
file for later analysis.
In this case, this would be the resulting file:

The name of the package which the file belongs to.
Version = 6.3.9600.16384,
File version (major, minor, build and revision).
pA = PROCESSOR_ARCHITECTURE_INTEL (0),
The targeted processor architecture.
Culture neutral, [...],
Either neutral or the related culture name if localized.
hash mismatch
Reason the file need to be repaired.
While the listed files are there, their hash doesn't match the expected value which means they are corrupted. All files except one share the same version, i.e. 6.3.9600.16384
. This means they are included as part of Windows 8.1 RTM. The portcls.sys
file has version 6.3.9600.17031
and it is part of the KB2919355 update:
2014-04-22 17:19:12, Info CSI 000004c1 [SR] This component was referenced by [l:162{81}]"Package_939_for_KB2919355~31bf3856ad364e35~x86~~6.3.1.14.2919355-2269_neutral_GDR"
At this point you need to replace the corrupted files.

Did you find a solution to this problem? Tough nut. – Milind R – 2014-08-07T06:03:33.930
@MilindR - No, this is crazy tough nut. I described the most fast fix in my own answer, about "repair" with keeping everything. Also, I started to do Windows backup images and restoring to those once in a month, after something broke. Also, I talked long with MS support guys, but they were unable to solve this too. – Kosmos – 2014-08-07T06:49:15.277
There seems to be some issues with the High Definition Audio Device too. Copy the

file located inC:\Windows\Logs\CBS
to the desktop, compress it in a .zip/.7z archive and upload it somewhere (e.g. http://ge.tt/about). Then post here the link.Yea. Sound also gone this time, but this is the least problem, if compare to keyboard. Looks like this log is overwriten by something. I already read it and it was a couple of MBs, now only 70 kb. i will run that command again and upload the result soon. – Kosmos – 2014-04-22T13:05:16.683
@and31415 - I did what you said. – Kosmos – 2014-04-22T13:26:35.293
Have you verified the system integrity by using
sfc
andDISM
? – Ramhound – 2014-04-22T13:55:10.153By sfc you mean something other than what I run? I used "sfc.exe /scannall" and I don't know anything about DISM. It looks like about WinPE for me. – Kosmos – 2014-04-22T13:59:04.350
1@Kosmos I've posted an answer which can help you understand which are the corrupted files. Before proceeding with manual repairs, open a command prompt as administrator and run this command:
chkdsk %systemdrive% /r
. It will ask you to schedule a disk check next time Windows starts. After giving the required confirmation, restart Windows and wait for the disk check to finish. Report back any errors that maybe be detected. – and31415 – 2014-04-22T14:07:10.450Ok, thank you. I will try it and see what happens. – Kosmos – 2014-04-22T14:09:53.010

@Kosmos To get the proper files you'll need a Windows 8.1 setup media. In case you don't have one, you can get the official trial. Just make sure to get the same version you have installed (e.g. 32-bit). I'll add the repair steps later on. By the way, the keyboard-related driver

is indeed corrupted.What is the make and model of your computer? – Bradley Forney – 2014-04-27T13:37:12.367
This is custom made by me computer from chosen by me parts. it work fine for a 4 years and will continue to work fine if I refresh windows 8.1, which I don't want that much. – Kosmos – 2014-04-27T13:49:52.637
because there is no guaranty that KB will continue to work after week or two passed. – Kosmos – 2014-04-27T13:58:10.573
