An SFC or System File Checker scan is a very useful feature that is built into every Windows operating system version. An SFC scan examines every system file for corruption and damage and repairs any problem with system files found by substituting the damaged or corrupted system files with entirely fresh, cached versions.
A successful SFC scan can solve a lot of different problems on a machine which is running Windows, but an SFC scan can also fail completely. At this point in time when an SFC scan fails, an error message explaining what went wrong and why the scan failed is displayed on the screen. Several Windows users see the error message Windows Resource Protection Cannot Perform the Requested Operation as a result of the failing of the SFC scan.
This message will be displayed at the end or may be shown in the middle when the scan gets stuck and fails simultaneously.
Also, the biggest reason to worry is that the "Windows Resource Protection Cannot Perform the Requested Operation" error has been spotted in all the Windows operating system versions which are currently in use, starting from Windows 7 till Windows 10.
We are not sure what is the specific reason for this error or its cause as it can differ from one scenario to another. Having said that, this problem is mostly connected with the SFC utility, for one reason or the other, not being able to access files that it either needs to operate or needs to scan for damage and corruption.
When an SFC scan fails and shows Windows Resource Protection Cannot Perform the Requested Operation error message, you can be assured that any damaged or corrupted system files that it may have got were not fixed, and that makes this issue a very important one.
Like most of the problems, even this one has a solution or solutions. Majority of the Windows operating system users who have encountered this issue, have overcome it using any of these 5 solutions written below :
Solution 1: Run the CHKDSK utility
CHKDSK is an inbuilt Windows utility which has the capability of scanning hard drive segments in order to test their file system integrity and fix logical file system issues. In few situations, running the CHKDSK utility resolves whatever problem was making the SFC scan to crash. In addition, it would also get this issue out of the system. This is one of the first and easy solutions which can resolve the issue of displaying the Windows Resource Protection Cannot Perform the Requested Operation error message. In order to apply this, we have to do the following :
1. Open the Start menu and type "cmd" on the search bar and click the search button.
2. Then right-click on the search result which says cmd and click on Run as administrator.
Note: You might be asked to provide confirmation or an administrator password. Just in case that happens, give whatever is needed.
3. After that, type this following into the elevated Command Prompt and press the Enter key:
CHKDSK C: /R
4. The moment the command is executed, you will be notified that the CHKDSK utility will run right after the next boot. As soon as that happens, type y into the elevated Command Prompt and press the Enter key.
5. Close the elevated Command Prompt.
6. Reboot your computer.
7. The moment your computer boots up, CHKDSK will start running. CHKDSK might take some substantial amount of time, depending on how large is your hard drive. Once that starts to happen, you have to be patient enough to wait until it is completely done.
As soon as CHKDSK is completed, your computer will start up usually, and you can run an SFC scan to conclude whether or not the issue has been resolved.
Solution 2: Modify the security descriptors on the winsxs folder
There can be one reason why SFC scan might have failed on an affected computer and that is the SFC utility cannot locate the winsxs folder (C:\Windows\winsxs). This can happen because of some problems with the folder’s security descriptors.
If that is the case, then you can solve this by doing the following :
1. Open the Start Menu
2. Go to Search and type “cmd” and search for it.
3. Right-click on the search result named cmd and click on Run as administrator.
Note: You might be asked to give confirmation or an administrator password. If that happens then provide whatever is needed in order to move ahead and execute this solution properly.
4. Type the following into the elevated Command Prompt and press the Enter key:
5. Once the command has been executed, close the elevated Command Prompt.
6. Reboot your computer and run an SFC scan when it boots up to check whether if the problem has been solved or not.
Solution 3: Perform a repair install of Windows
A repair install is an alternative that all Windows users have – this choice enables users to fix all important system files and resolve almost any problem that is troubling their computers. Even though it is regarded to as a “repair install”, it does not reinstall Windows.
Alternatively, a repair installation only fixes as many issues with the affected computer as possible, and since that is the problem, a repair install can be done without the loss of any data which saved on the computer being in question.
There is a rather fair possibility that doing a repair install will be able to repair whatever is making SFC scans on your computer to fail and display the Windows resource protection cannot perform the requested operation error message. In addition, to top it all off, doing a repair install is a much easy and straightforward method.
Solution 4: Clean install Windows from scratch
Just in case, if even a repair install of Windows is not able to resolve this issue in your situation and SFC scans still fail on your computer after the repair install, your best chance would surely be to clean install Windows from the beginning.
Clean installing Windows involves cleaning your current installation of Windows clean – along with all installed applications and any stored data and then installing a completely fresh, new Windows Operating System which, in almost all cases, is the exact same version of Windows that was previously installed on the computer in question.
This entire process can help you to eradicate the display of Windows resource protection cannot perform the requested operation error message.
Just because clean installing Windows indicates you are going to be reinstalling Windows from the beginning and your computer will be like new afterward, there is a very genuine possibility that the clean installation will help you to get rid of this issue.
As a clean installation also gets rid of any and all data stored on the objective computer, it is profoundly advised that you keep a backup of all the data which you don’t want to lose before you progress with the clean installation.
On the off-chance that your computer remains affected by this problem even after you clean install Windows, the only remaining plausible explanation for the issue is that your computer’s HDD/SSD has failed or is beginning to fail.
The SFC utility may not be able to access the files it needs to operate or the files it needs to scan because they are located on sectors of your computer’s HDD/SSD that have already gone bad, and if that’s the case, your best course of action is to find out if your HDD/SSD really has failed or is failing, and then restore it before something unfortunate occurs.
However, you can also choose to have an expert take a glimpse at the HDD/SSD, just in case. In addition, if the HDD/SSD is still under warranty, it is profoundly advised that you send it off to the manufacturer to have it checked out and if it really has failed or is failing, fixed or replaced.
Solution 5 : Run SFC in safe mode
There is this last one solution, which might just be as helpful as the others. It has been reported by many users that, this method has actually helped them while resolving the issue of Windows resource protection cannot perform the requested operation error message is shown as a result of a failed SFC scan.
1. Press the Windows logo key and R key at the same time to start the Run box.
2. After this type msconfig and press the Enter key.
3. Click Restart when asked by System Configuration.
Your Windows will then boot into safe mode.
4. Run sfc /scannow to see if it works now or not.
