Windows 8 Windows 8.1 x64 Corrupted system files

I ran the SFC tool after my computer crashed while gaming online. I received the following error message.

Cannot repair member file [l:24{12}]"utc.app.json" of Microsoft-Windows-Unified-Telemetry-Client, Version = 6.3.9600.17747, 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
and

afterwards the repair attempt yielded this message

Could not reproject corrupted file [ml:520{260},l:114{57}]"\??\C:\ProgramData\Microsoft\Diagnosis\DownloadedSettings"\[l:24{12}]"utc.app.json"; source file in store is also corrupted

and

Where can I find the system files to correct this problem? The sfcdetails file is attached. System info attached.

Please, can you help?
