Fix Windows Resource Protection Could Not Start the Repair Service
Struggling with the “Windows Resource Protection could not start the repair service” error while attempting to run the System File Checker (sfc /scannow)? Well, it can be really frustrating. This is because the System File Checker is a valuable tool trusted by countless users to address system-wide problems by autonomously identifying and repairing corrupted or missing files that may have been causing trouble on your computer. However, you may feel helpless in such a situation when the very tool designed to fix your PC’s problems encounters its own set of issues! But worry no more, you’ve reached the right place, in today’s post, we are going to understand the process of resolving the issue “Windows Resource Protection could not start the repair service” with some simple methods. Let’s get started.
“Windows Resource Protection could not start the repair service” is a phrase that spells frustration for many Windows users. Typically, this error pops up when trying to make use of the System File Checker tool, activated by the command “SFC /SCANNOW.” This tool’s vital role is to scan and mend Windows system files, ensuring the integrity of your operating system. However, the common reason behind its failure is the TrustedInstaller service, which is designed to safeguard core system files from accidental tampering. However when it comes to individual system files, they can still be vulnerable to corruption due to unforeseen circumstances. Now, without much ado, let’s begin with methods to rectify this issue and restore your system’s health. This method is carried out within the Command Prompt and is worth trying, as it requires administrative privileges for the modification. If the command is successful, you’ll see a “SUCCESS” message. You should receive a message indicating that the Windows Modules Installer service has started successfully. There’s a chance that an underlying application or service might be causing interference with the System File Checker, preventing it from functioning properly. In such a scenario, you can attempt to run the scanning command in Safe Mode. The simplest solution involves manually re-initiating the necessary service. Here’s what you need to do. Certain users have reported that using the DISM command resolved the issues with the System File Checker. The Deployment Image Servicing and Management (DISM) tool essentially reinstalls your system image to address problems directly associated with it. Below are the step-by-step instructions: If you’re comfortable working with the Windows Registry editor, you can resolve this error by adding a new expandable string value to the Registry. However, please be cautious, as incorrect modifications to your registry entries can have serious consequences. Note: Before proceeding with the setup, it’s essential that you make a backup of Windows registry files and establish a system restore point, allowing you to revert system-level changes and restore your PC’s functionality. Once you’ve taken these precautions, follow the steps outlined below. This process is a bit complicated and technical. Therefore, to make the procedure more manageable, we’ve divided it into two parts. Now that you have the necessary information, it’s time to add an Expandable String value in the Registry Editor. Here’s how to do it: %SystemRoot%\winsxs\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.19041.1XXX_none_7e3d47227c694b34. Note: If you encounter an “Error creating value” message while adding a subkey or string value, it’s necessary to take ownership of the Component-Based Servicing key. You can accomplish this by following the steps below. How to Take Ownership of a Registry Key Once you are done with making necessary changes in the Registry, reboot your computer and then check if the SFC scan is running effectively or not. There are times when you need not perform all these technical steps; you can simply perform automatic repair, and the system may fix the issue on its own. Here’s how to do it. Once done, reboot your PC normally to Windows and see if the SFC scan works as expected. Although the “Windows Resource Protection could not start the repair service” error is frustrating, it can be resolved successfully.
