What is sfc /scannow?

SFC is the short form of System File Checker and it is a Windows utility that helps users check file corruption and repair registry data. System File Checker is a function of modern Windows system including Windows Vista, Windows 7, Windows 8 and Windows 10.

System File Checker allows users to launch a command prompt window and start a system scanning so that you can check whether protected system files are corrupted or not. The sfc / scannow is the very command that enables System File Checker utility to scan all protected system files for your PC. It is capable of verifying file versions and repairing incorrect files by replacing when with those from a repair source. Thus, it is quite helpful to solve system issues caused by file corruption.

How to use sfc / scannow? It is well known that the corruption of system files that affects system running is one the most annoying problems we may encounter. In this case, we can use the command to troubleshoot such issues. Launch an elevated Command Prompt or run PowerShell (Admin), and then type in sfc / scannow and press Enter key. This triggers an SFC scan, which will analyze all system files on the computer and set aside corrupted or lost system files so as to fix them via uncorrupted cached copied.

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

Although sfc / scannow is effective in most cases, there are some situations that it cannot deal with. For instance, it counts on cached copies of normal system files to repair corrupted system files, and the command won't be able to work as expected once the cached copies of system files are also corrupted for some reason. At this rate, you will receive error such as:

"Beginning system scan. This process will take some time. Beginning verification phase of system scan. Verification 100% complete. Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\.log. Note that logging is currently not supported in offline servicing scenarios."

Here is one the of real case about the issue:

"Hey guys, I just installed the latest system updates and made a clean installation of print driver. However, it began to periodically lock up. I thought it might be fixed with sfc / scannow , but this ended up with 'Windows Resource Protection found corrupt files but was unable to fix some of them.' I'm not a computer geek and cannot understand how to check that log file. I searched the issue for solution, but in vain. Hope anyone here can give me some advice to fix corrupted files and computer freezing issue."

It is important to fix corrupted system files in order to keep operating system working smoothly. Despite that sfc / scannow cannot repair the problem, there are alternative solutions. So, without wasting any time, let's see several solutions below and fix corrupted system files as soon as possible.

Solution #1: Check CBS.log file manually

Step 1. Open File Explorer and type C:\Windows\Logs\CBS in the address bar and press Enter. Then you can see the CBS.log file.

Step 2. Double-click the file to view file content. Press Ctrl and F key and enter Corrupt to look for corrupted files. Then you can find out corrupted files that cannot be fixed by SFC. Then type the query in searching engine to look for solution.

If you are not allowed to access it, you can follow these steps to remove limitation: Right-click on the CBS.log file and select Properties; Click Security tab and click Advanced button; click Change under Owner; enter Everyone and click Check Names and click OK; Click Apply and OK; again right-click the CBS.log file to open Properties, and click Security tab to choose Everyone; make sure to select Full Control and save changes.

Solution #2: Run sfc / scannow in safe mode

Step 4. Type sfc/scannow and press Enter. When process completes, boot to Windows and open System Configuration again, and uncheck the "Safe boot" option.

Solution #3: Check and repair hard drive errors

Hard drive errors can be the cause of many issues and you can have a check if the hard drive contains bad sectors. Here we can use free bad sector repair software to scan hard drive and verify bad sectors.

Step 1. Install and launch DiskGenius Free from your computer. Select the hard drive which contain system partition, and click Verify Or Repair Bad Sectors from Disk menu.

Step 2. Click "Start Verify" button and DiskGenius starts to scan the select disk and check if there are any bad sectors.

Note:

Checking bad sectors is safe, as it is read-only process. But bad sector repairing is not read-only and it may cause data loss, thus you should create a backup of important data before trying to repairing bad sectors. If your hard drive contains bad sectors, you'd better backup important files to a different disk, and then try repairing bad sectors. If bad sectors are not repairable, you may have to consider replacing the hard drive with a new one.

Solution #4: Restore system from backup

Windows System Restore is a useful function which is able to restore operating system to an earlier state. If your computer has enabled this feature and you cannot fix corrupted or missing system files, you can try restoring system.

Step 1. Type "restore" in searching box and choose "Create a restore point" from the searching result.

Step 3. The system restore wizard shows up and click Next button from the welcome page.

Note: System restore can help fix problems that might be making your computer run slowly or stop responding. System restore does not affect any of your documents, pictures, or other personal data. Recently installed programs and drivers might be uninstalled.

Step 4. Select the restore point you want and click Next button.

Select "Show more restore points" to let the system restore wizard show all available restore points. Select the time point you want to restore. It is recommended to select the most recent working restore point. Besides, you can click Scan for affected programs button to have a check if any software will be removed during the process.

If you've never enabled system restore feature in Windows, there is not any restore point here and you cannot perform system restore. Alternatively, system restore can be done if you've backed up with third-party software. Windows built-in system restore feature backed up data automatically regularly, however which takes more disk space. Therefore, most users prefer to backup & restore Windows and personal data with third-party software. If you haven't created any back up for your computer, you can backup now.
