3 built-in Windows file repair tools you need

When applications do not work properly, or Windows crashes for no apparent reason, it is likely that corrupted files are the cause. Windows will immediately display an error message stating that the file is corrupted or unreadable. There are many file repair tools that you need to install, or we can immediately use 3 hidden file repair features available on Windows, according to the article below.

Using SFC to fix basic file errors

When you suspect corrupted system files, you can immediately use the SFC (System File Checker) tool. You need to open Command Prompt as administrator , then type sfc /scannow and press Enter .

1. Use the SFC scannow command to fix system file errors

The scan will complete with a message saying no problems, errors found and fixed, or some errors that could not be fixed.

Use DISM to fix Windows component store errors

Windows component store is a folder that contains important Windows system files, used to repair, update, and install operating system components.

In case you use SFC but it reports an error and no problem is found, you can use DISM.

We open Command Prompt as Admin then enter DISM /Online /Cleanup-Image /RestoreHealth .

Fix computer boot file errors

Windows 11 has a feature called Windows Recovery Environment (WinRE) . You don't need to do anything to access it if your computer won't boot. WinRE will launch automatically after three failed boot attempts. All you have to do is click the Startup Repair option and follow the instructions.

This will determine what is causing Windows to fail to boot and fix the problem.
