I need this error fixed.... HELP!

Answer 1

I got :- Windows Resource Protection found corrupt files but was unable to fix some of them.

Answer 2

Please run System File Checker. Select the keyboard shortcut Win+X, and click Command Prompt (Admin) on the drop down menu. Type cd* and press the ENTER key. Type sfc /scannow and press the ENTER key*.** Please say what is reported when the check completes.

After the process has finished, you may receive one of the following messages:

•Windows Resource Protection did not find any integrity violations.

•Windows Resource Protection could not perform the requested operation.

•Windows Resource Protection found corrupt files and successfully repaired them.

•Windows Resource Protection found corrupt files but was unable to fix some of them.

Which message was received?

Answer 3

Run SFC 3 times, then if that doss not work, use Dism /Online /Cleanup-Image /RestoreHealth

Kindly re-read and follow the eightforums information that I gave you as that will be much easier.

Answer 4

Hey, thanks for your reply! Will try these out when I have the time. If it fixes my problem then I will mark your answer the best. BTW, I did do sfc /scannow before and that did not help me but I did not replace the unfixed files manually. Will do that now. Also, will refreshing my PC wipe out all my data?

Answer 5

Hi,

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"

http://support2.microsoft.com/kb/929833?wa=wsignin1.0#manually repair

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"

Cheers.
