I had some corrupted system files. I have run sfc /scannow several times, and Dism ... RestoreHealth (followed by sfc /scannow again). This has fixed nearly everything, but I am left with the following two corrupted files:

"2015-07-21 13:14:46, Info                  CSI    0000047e [SR] Cannot repair member file [l:24{12}]"utc.app.json" of Microsoft-Windows-Unified-Telemetry-Client, Version = 6.3.9600.17842, pA = PROCESSOR_ARCHITECTURE_AMD64 (9), Culture neutral, VersionScope = 1 nonSxS, PublicKeyToken = {l:8 b:31bf3856ad364e35}, Type neutral, TypeName neutral, PublicKey neutral in the store, hash mismatch

2015-07-21 13:14:46, Info                  CSI    00000480 [SR] Cannot repair member file [l:66{33}]"telemetry.ASM-WindowsDefault.json" of Microsoft-Windows-Unified-Telemetry-Client, Version = 6.3.9600.17842, pA = PROCESSOR_ARCHITECTURE_AMD64 (9), Culture neutral, VersionScope = 1 nonSxS, PublicKeyToken = {l:8 b:31bf3856ad364e35}, Type neutral, TypeName neutral, PublicKey neutral in the store, hash mismatch

2015-07-21 13:14:48, Info                  CSI    00000484 [SR] This component was referenced by [l:154{77}]"Package_1_for_KB3068708~31bf3856ad364e35~amd64~~6.3.1.0.3068708-1_neutral_GDR"

They appear several times in the CBS log file for the last instance of scf /scannow. As far as I am aware, I have no AMD hardware in the system, so can I safely ignore this? If not, how can I repair the files? I note that the relevant update (KB3068708) is listed as optional, so would uninstalling it solve the problem?

I am running Windows 8.1 Pro and I have the (Windows 8) installation DVD.

  • Your title doesn't make sense, it refers to "uncorrupted files"?

    The files are not connected to AMD hardware, all 64-bit references is designated as AMD64, because AMD designed the 64-bit extension for x86. You need to find a new source for KB3068708, you can easily enough extract that from a working system, if you want. A corrupt .json file can be safely ignored, or again extract, from a known working system.

  • Probably the title was badly constructed. I wanted to ask how to locate the uncorrupted versions of the files, but this is now redundant following the answer below.

  • @PatrickC - You should still fix the title.

Those files show as corrupted for anyone who installed the KB3068708 update - https://support.microsoft.com/en-us/kb/3068708

This update contains the following two manifests that are occasionally updated by the Diagnostic Tracking Service:

  • telemetry.ASM-WindowsDefault.json
  • utc.app.json

The two files are marked as static files in the update. When an advanced user runs the System File Checker Tool (sfc.exe), the files are unintentionally flagged as corrupted. There is no impact or actual corruption on a device that is running this update, and this issue will be fixed in a later service update

Microsoft are aware of the issue and state it will be fixed at a later date.

Optionally, you can uninstall the update to resolve the issue but this isn't necessary. Having SFC show the two files as corrupt doesn't cause any issues.
