Yesterday evening, my boss sent me an email complaining about problems mapping network drives (Server 2008r2) and connecting to the office LAN after setting up offline files. He tried troubleshooting to no avail. I suggested SFC.exe and/or a systems restore. However neither one worked.

 System restore failed to extract file C:\Users\...\local\Packages\microsoft.windowscommunicationsapps_8v from the restore point.

  Unspecified error (0x8007045b)

 SFC.exe /scannow does report that it found errors, but could not fix them.  I have a CBS.log file that I could post somewhere...

 All this on a Surface Pro 3 running Windows 8.1

  

Kindly go through the detailed suggestions as mentioned in the following thread:

Did you run DISM?  Instructions for which are at the end of this wiki

All instructions are in our Wiki article below...
Should you have any questions please ask us.

System file check (SFC) Scan and Repair System Files

 Well, we weren't aware of DSIM, but it sure worked well for us! Also re-ran SFC.exe afterwards and that came up clean and all of the lost functionality was restored.

There are a whole host of options for running DISM.  Only works in win 8 and above.  Unfortunately it is broken in the current win 10 build.

Thanks fr letting us know

Stumped here. System restore reports same

C:\Users\...\local\Packages\microsoft.windowscommunicationsapps_8v from the restore point.

  Unspecified error (0x8007045b)

SFC 3x squeaky clean

DISM /Online /Cleanup-Image /RestoreHealth  reported success. Still same issue - unable to do any system restore from any restore point.

(trying to restore because suddenly Miracast went off to a parallel universe on my SP3..)

--I've run SFC and DISM multiple times. Neither find any errors. I'm stumped--
