Purpose

Windows Resource Protection (WRP) prevents the replacement of essential system files, folders, and registry keys that are installed as part of the operating system. It became available starting with Windows Server 2008 and Windows Vista. Applications should not overwrite these resources because they are used by the system and other applications. Protecting these resources prevents application and operating system failures. WRP is the new name for Windows File Protection (WFP). WRP protects registry keys and folders as well as essential system files.

If a Windows Resource Protection (WRP) file is missing or is corrupted, your Windows probably cannot work properly. SFC ( System File Checker ) tool can help you scan and repair corruptions in Windows system files. WIndows resource protection has found some corrupt files. No Fix in Performance & Maintenance Hello, I have tried to run sfc/ scannow and it gives me the notification that: WIndows resource protection has found some corrupt files but is unable to fix some of them.

Where applicable

All Windows-based applications and their installation programs that run on Windows Server 2008 or Windows Vista, and later operating systems, should be aware of WRP. All Windows-based applications that run on Microsoft Windows Server 2003 or Windows XP and their installation programs should be aware of WFP.

Developer audience

The WRP API is designed for use by C/C++ programmers. The WRP API has two functions: SfcIsFileProtected and SfcIsKeyProtected.

Run-time requirements

Applications that use only the SfcIsFileProtected function require Windows Server 2008, Windows Vista, Windows Server 2003, or Windows XP. Applications that use the SfcIsKeyProtected function require Windows Server 2008 or Windows Vista.

We have already seen how the System File Checker allows users to scan for and restore corrupt Windows system files. We have also seen how to run System File Checker and more, earlier. But what if at the end of the run you see the following message?

Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log windirLogsCBSCBS.log.

What this message says is that although the System File Checker completed the scan and found corrupted system files, it was unable to proceed and replace them with good system files.

The Windows Resource Protection protects registry keys and folders as well as critical system files. If any changes are detected to a protected system file, the modified file is restored from a cached copy located in the Windows folder itself.

If you receive this message and the System File Checker is not able to do its job when you run it, here are a few things you can try.

1] Boot into Safe Mode. Open an elevated command prompt windows, type sfc/scannow and hit Enter. Just make sure that the PendingDeletes and PendingRenames folders exist under %WinDir%WinSxSTemp. This may help if some start-up programs are creating a problem.

2] If you wish to or need to, you may run System File Checker at Boot Time. This is one option which may help you as it will run System File Checker before Windows loads. Go here to learn how to run sfc /scannow at Boot Time. See if this helps.

3] Use DISM. Open an elevated command prompt and run the following command and hit Enter:

This command checks for component store corruption, records the corruption and FIXES the corruption. It may take a while though! Useful if System File Checker is not working.

4] On Windows 10, try Reset This PC or Fresh Start. On Windows 8, carry out a Refresh or a Reset operation. An Automatic Repair is also an option you may want to consider if you think it applies in your situation. On Windows 7, carry out a Startup Repair or Repair Install or an In-place Upgrade as you think may best suit your situation.

To perform an In-place upgrade in Windows 7 or Windows Vista, back up your documents, close all open applications and then insert the Windows DVD in the DVD drive. In the Setup window, click Install Now. Click Go online to obtain the latest updates for installation (recommended). Type the CD key if you are prompted to do this. Next, select the operating system in Install Windows page you want to Upgrade or In-place and click Yes to accept the Microsoft Software License Terms. Next click Upgrade when asked Which type of installation do you want. Once the process is completed, restart your PC.

5] You may also want to consider this option. Open the CBS.log file and view details of the corrupted files and replace the corrupted file with a known good copy manually. Navigate to C:WindowsLogsCBS you will be able to see and open the SBS.log file.

Check if it shows some errors or a message. That may give you a direction to proceed. You can get more details on how to do this manually, here at KB929833.
