Repair Corrupt Registry in Windows 10 Error

Dealing with your Windows registry could lead to a bricked Windows system. If you have damaged your Windows 10 registry, you should repair it as soon as possible as you may lose your data.

Normally, you can get a corrupted registry error after making changes in the registry editor. Therefore, it is more than recommended to save the registry before making changes, as you will find all the internal settings of your Windows 10 system there.

Fix 1 - Use Windows Registry Checker Tool

Windows Registry Checker automatically scans the system registry for invalid entries and empty data blocks when it is started. If invalid registry entries are detected, Windows Registry Checker automatically restores a backup of the previous day. This corresponds to the execution of the scanreg /autorun command from a command prompt. If no backup is available, the Windows registry checker will attempt to repair the registry. This corresponds to the execution of the scanreg /fix command from a command prompt. If the registry contains more than 500 KB of empty data blocks, Windows Registry Checker automatically optimizes them.

The protected version of Windows Registry Checker (Scanregw.exe) can create a backup of system files and search for invalid entries in the registry. If invalid entries are found, it refers to the real mode version of the Windows Registry Checker tool (Scanreg.exe) for a resolution.

You can configure Windows Registry Checker with a ScanReg.ini file. Settings you can configure:

  1. Activate or deactivate the tool
  2. The number of backups maintained (no more than five are recommended)
  3. The location of the backup folder
  4. Settings to add additional files to the backup set

Fix 2 - Run SFC command to repair system files.

When troubleshooting a Windows system failure, execute the SFC command. SFC scans and replaces damaged, missing or modified system files. Even if the SFC command does not repair any files, it will at least confirm that no system files are corrupted, and you can continue editing your system using other methods. You can use the SFC command as long as the computer starts by itself. If Windows starts normally, you can run it from an administrative command prompt. If Windows does not boot normally, you can try starting it in safe mode or in the recovery environment by booting from the installation media or the recovery CD.

No matter how you access the command prompt - usually in safe mode or in the recovery environment - you will use the command in the same way. If you start Windows normally, you must open the command prompt with administrator rights. To do this, right-click the Start button and select "Command Prompt (Admin)".

At the command prompt, type the following command and press Enter to perform a complete analysis of the system and SFC repairs:

sfc /scannow

Fix 3 - Perform an automatic repair

To perform the automatic repair that attempts to repair a corrupted registry on your Windows 10 system, follow these steps:

  1. Open the parameters window
  2. Go to Update and Security
  3. On the Restore tab, click Start -> Restart Now.
  4. On the "Select an option" screen, click Troubleshooting.
  5. On the Advanced Options screen, click Auto Repair.
  6. Select an account and log in when prompted.
  7. The automatic repair should now begin and your computer can be restarted during this process.

Fix 4 - System Restore/Reset

If all the above steps did not help, the system recovery tool will restore your operating system files to a previous state, at a time when the files were not corrupted.

To do this, click the Start/Windows button at the bottom left of the screen. Enter System Restore in the search bar and click "Create restore point". Then click the System Restore button in the system properties. Activate the "Enable system protection" button and move the Max Usage slider up to about 5-10%. This determines how much of your hard disk should be used for recovery. Then press Apply.

You can also reset your system or reinstall Windows. This deletes applications and settings, but your personal files are preserved if you wish. To do this, click Settings > Update & Security > Restore (left pane) > Start. You will then have to decide whether you want to keep "My Files" or "Delete All", depending on whether you want to keep your files on your computer.
