Use System File Checker (SFC) Command on Windows 10 & 11

Windows is a widely-used operating system that provides a stable and reliable platform for users to perform various tasks. However, like any other software, it is not immune to errors and malfunctions that can cause inconvenience and frustration to users.

If you are experiencing issues with your Windows operating system, such as certain functions not working or Windows crashes, then you might want to consider using the System File Checker (SFC) to scan Windows and restore your files.

The SFC is a built-in Windows utility that scans and repairs damaged or corrupted system files. It is a powerful tool that can help you fix a range of issues, including blue screen errors, system crashes, and other problems related to the operating system. By running an SFC scannow command, you can restore missing or corrupted files and ensure that your system is functioning properly.

If you are unsure about how to use the SFC tool, don’t worry. In this guide, we will walk you through the process step-by-step. While the steps may seem complicated at first, just follow them in order, and we’ll try to get you back on track.

Run SFC scannow command on Windows 10

Before we get started, it is important to note that the SFC tool requires administrative privileges to run. Therefore, you should ensure that you are logged in to your Windows account as an administrator. If you are not sure whether you have administrative privileges, follow these steps:

• Click on the Start and type “cmd” in the search bar.
• Right-click on the Command Prompt and select “Run as administrator“.
• If prompted, enter your admin password and click “OK“.

Once you have confirmed that you have administrative privileges, you can proceed with the SFC scan. Here’s how to do it:

Step 1: Open Command Prompt

Click on the Start menu and type “cmd” in the search bar.

Right-click on the Command Prompt and select “Run as administrator“.

If prompted, enter your admin password and click “OK“.

Step 2: Run the SFC Scannow command on Windows 10

In the Command Prompt window, type “sfc /scannow” and press Enter.

The scan may take some time to complete, so be patient and do not interrupt the process.

Once the scan is complete, the SFC tool will display a message indicating whether any issues were found and whether they were fixed.

Step 3: Restart Your Windows

After the scan is complete, restart your computer to apply any changes that were made during the scan.

Once your computer has restarted, check whether the issues you were experiencing have been resolved.

In some cases, the SFC tool may not be able to fix all the issues it finds. If this happens, you can try running the scan again or use other troubleshooting methods to address the problem. You can also seek help from a professional if you are unsure about how to proceed.

Run SFC scannow command on Windows 11

While the System File Checker (SFC) is still present in Windows 11, there are a few changes in how to access it compared to Windows 10.

In Windows 10, you can access the SFC tool by typing “sfc /scannow” in the Command Prompt window, which can be opened by searching for “cmd” in the Start menu.

In Windows 11, however, Microsoft has introduced a new feature called Windows Tools that combines several system tools, including the SFC, into a single menu. To access the SFC in Windows 11, follow these steps:

Click on the Start button and select Windows Tools from the menu.

Click on System File Checker to open the SFC tool.

In the SFC window, click on Scan now to start the scan.

The rest of the process is the same as in Windows 10. The SFC will scan your system files and attempt to repair any issues it finds.

It’s worth noting that Windows 11 also includes a new feature called “Deployment Image Servicing and Management” (DISM), which can be used alongside SFC to repair Windows images. To use DISM, open the Command Prompt as an administrator and type “dism /online /cleanup-image /restorehealth”. This will scan your Windows image and attempt to repair any issues it finds.

Overall, while the SFC tool works in a similar way in both Windows 10 and 11, the method for accessing it has changed slightly in the newer operating system.

Use SFC on Windows 7 or 8

You can use the System File Checker (SFC) command on Windows 7 and Windows 8 just like you can on Windows 10. The steps to use the SFC command on Windows 7 or 8 are slightly different from those on Windows 10, but the basic process is the same.

To use the SFC command on Windows 7 or 8, follow these steps:

• Click on the Start menu and type “cmd” into the search bar.
• Right-click on the Command Prompt application and select “Run as administrator“.
• Type “sfc /scannow” into the Command Prompt window and press Enter.

The SFC tool will begin scanning your system files and will replace any corrupted or missing files with a cached copy from your system.

Note that on Windows 7 and 8, you may need to insert your Windows installation disc if the SFC command finds any corrupted system files that it cannot repair with cached copies.
