SFC cannot fix corrupted files in Windows 7 -- Windows Update for May 2015?

https://support2.microsoft.com/default.aspx?scid=kb;en-us;3022345

KB3022345 does NOT cause file corruption.

Summary

This update enables the Diagnostics Tracking Service in Windows 8.1, Windows Server 2012 R2, Windows 7 Service Pack 1 (SP1), and Windows Server 2008 R2 SP1. This tracking service collects data about functional issues in Windows.

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 corruption on a device that is running this update, and this issue will be fixed in a later service update.

Thanks for the information Susan,

is the following anything to worry about, and if so, is there a fix?

I believe it has hit me too.  I manage 2 Windows 7 systems, one a 12GB tower and one a 4GB laptop, and both have started showing SFC failures.  I tried looking at the logs suggested, and there seemed among other things to be suggestions of multiple ownerships (is that possible?) on files which I believe were in the PendingRenames folder.  Certainly PendingRenames was not being emptied, and had appalling numbers of files in them: something like 2,000 on the laptop, and well over 10,000 on the tower.

Whether coincidentally or consequently, Avira Antivirus on the tower is now crashing when it tries to start.  Attempts either to repair the installation from the programs removal control panel, or simply to remove it and reinstall, both ran into error alerts I've never seen before.  So right now I can neither run it nor re-install it, which is both rather amazing and quite bad.

I have removed the KB3022... update on the tower, and I'm about to see if I'm any further forward, both with SFC and with Avira.

As another respondent has mentioned, I'd like to hide KB3022345 from Windows Update, but I can't seem to find any reference to it now, apart from in the Update history.  Maybe that's a good thing, but it would be more secure if I could make certain it never slips in again.

Thank you very much for this discovery, I was going a little mad over it -- I've pretty well accepted the proposition that Windows updates are intact and an improvement when they come out, despite my innate software engineer's wariness of such claims.  Isolating a bad one among that whole stream of them would not have been easy.  It's hard enough just to do a clean boot when the system makes no provision to let you save your own typical configuration to be restored after debugging.

The System File Checker corruption can be resolved by installing update for customer experience and diagnostic telemetry:

I believe KB3022345 is the older of the two and was subsequently REPLACED by KB3068708.  I do not think you will find both on any system.

I just ran sfc/ scannow and found no corrupt files. Microsoft is pushing telemetry updates for data mining that I have removed. They serve no security purpose and are only there to further Microsoft's data mining exploits. This is the list of updates that are unnecessary:
