Question

Have read and found the  corrupt files that sfc could not repair. Now how do I repair them.

Answer 1

This may throw some light on it:

http://www.sysnative.com/forums/windows-update/11384-system-file-checker-cannot-repair-file-file-cannot-be-decompressed.html

From the above link:

What we do know is that *Windows 8* introduces a new system for compressing the winsxs folder and SFC doesn't seem to like it. What's also interesting is some testing with the new Windows 10 build shows this same issue out of the box with a clean install on two systems. Now that is very odd indeed, but slightly off topic from your issue here.

Cheers.

Answer 2

It is the only failure to repair in the log, sprinkled throughout the log from top to bottom. Files are different but with same explanation. Have even re-downloaded iso and re-burned to DVD and reinstalled same issue but at this point I am unsure what issues if any is being caused.

Answer 3

Have finished following the tips in your post and have gotten some where but am left with Multiple files (to many to count) that say "file cannot be decompressed. Can you tell me exactly what this means?

There are a lot of tips there, from SFC Scan to Reset Windows.

What part did you try and where does this message occur?

Cheers.

Hi,

Each Method/step below progresses to the next if the first does not fix any corrupted files that are found, etc.

Have you read this Microsoft information about repairing corrupt system files and errors?

"Use the System File Checker tool to repair missing or corrupted system files"

And these eightforums.com Tutorials are very detailed for problems resulting from SFC Scan:

"How to Run "SFC /SCANNOW" Command at Boot or in Windows 8 and 8.1"

http://www.eightforums.com/tutorials/3047-sfc-scannow-command-run-windows-8-a.html

Read this Section there in conjunction with the rest of the information they give in above link.

   Note

If SFC could not fix something, then run the command again to see if it may be able to the next time. Sometimes it may take running the sfc /scannow command 3 times restarting the PC after each time to completely fix everything that it's able to.

If not, then run the **Dism /Online /Cleanup-Image /RestoreHealth**command to repair any component store corruption,

Repair-WindowsImage -Online -CheckHealthRepair-WindowsImage -Online -ScanHealthRepair-WindowsImage -Online -RestoreHealth

Restart the PC afterwards, and try the sfc /scannow command again.

If still not, then try using OPTION ONE above to run the sfc /scannow command at boot

If still not, then you could do a refresh of Windows 8, or run a System Restore using a restore point dated before the bad file occured to fix it. You may need to repeat doing a System Restore until you find a older restore point that may work.

If still not, then you can use the steps in the TIP box in the OPTION THREE section to manually replace the files that SFC could not fix.

Refreshing your PC goes like this:

• The PC boots into Windows RE (RecoveryEnvironment).
• Windows RE scans the hard drive for your data, settings, and apps, and puts them aside (on the same drive).
• Windows RE installs a fresh copy of Windows.
• Windows RE restores the data, settings, and apps it has set aside into the newly installed copy of Windows.
• The PC restarts into the newly installed copy of Windows.

"When you reset your PC, the drive will be completely reset, and all your apps and files will be removed from it. Windows 8 will be reinstalled, and you'll need to change any settings and reinstall any apps that you want to get back after resetting. If you know if any files that you don't want to lose, then you should back those files up before starting the reset"
