So let's fix the broken items in your registry right now!

Quick access:

1. Method 1: Run the System File Checker (SFC)
2. Method 2: Use Disk Cleanup
3. Method 3: Run Windows Startup Repair
4. Method 4: Run the DISM Tool
5. Method 5: Restore a Backup Registry File

The Windows Registry is a core database in Microsoft's Windows operating system that stores configuration information for both the system and applications. It contains data about hardware, software, user settings, installed programs, and other vital system components. The registry is an essential part of Windows system management and configuration, enabling the operating system to access these settings quickly during runtime. In the registry, information is organized into keys, subkeys, and values. The main root keys are: 1. HKEY_LOCAL_MACHINE (HKLM) - Stores settings related to the local computer. 2. HKEY_CURRENT_USER (HKCU) - Holds personalized settings for the currently logged-in user. 3. HKEY_CLASSES_ROOT (HKCR) - Registers file types and their associated applications. 4. HKEY_USERS (HKU) - Contains configuration information for all users. 5. HKEY_CURRENT_CONFIG (HKCC) - Stores current system hardware configuration. 6. HKEY_DYN_DATA (HKDD) - Present in Windows 9x and ME for dynamic data storage, but no longer used in later versions of the OS. While the registry is crucial to the Windows system, directly editing it can pose risks to system stability, as incorrect modifications can lead to system crashes or application malfunction. Therefore, it's generally advised to modify the registry only with adequate knowledge or by using reliable tools.

The Windows Registry is a vast database that contains settings, options, and values for hardware and software installed on the Windows operating system.

The Registry has two basic elements: keys and values. Whenever you install new software, run a program, or change a hardware setting, Windows checks the Registry for the relevant keys and values.

To customize your Windows workflow or improve performance, you can modify registry keys using the built-in Windows Registry Editor (Regedit). However, proceed with caution when editing registry keys, as this can severely damage your operating system if done incorrectly.

Damaged Registry Entries Cause

Before we proceed with fixing corrupted registry entries in Windows 11, let's understand some reasons that might lead to corrupted registry items, such as:

- Malware and viruses can attack and modify the Windows Registry, leading to corrupted or damaged registry entries. - The installation or upgrading of certain software may cause fragmentation in the registry, which is a common reason for registry corruption. - An unexpected shutdown or crash of your computer can also result in registry errors. - Furthermore, when an accumulation of unnecessary, empty, or damaged entries clogs your system, it can impact the registry items. - Connecting faulty hardware or external devices to your computer might also lead to damaged registry entries. - Accidentally deleting or modifying registry settings can severely harm your operating system as well.

Now that you're aware of what can damage the Windows Registry, let's explore how to fix all corrupted registry entries on Windows 11.

Method 1: Run the System File Checker (SFC)

The System File Checker, or SFC, is a built-in utility in Windows 11 designed to scan for and repair corrupted or missing files within the system file directory. To use SFC to fix registry entries, follow these steps:

Step 1: Type "cmd" or "Command Prompt" in the search bar.

(This image displays the Command Prompt interface in the Windows 11 operating system, used for disk partition management.)

Step 2: Right-click on Command Prompt and select "Run as administrator" to open cmd.

Step 3: Type the command sfc /scannow in the Command Prompt window and press Enter.

This command will scan all of your system files and look for any corrupt ones. A full scan can take 30 minutes or more.

However, if you still receive the 'Windows Resource Protection found corrupt files but was unable to fix some of them' message after running the SFC command, restart your computer and try again. Or, you can try the other methods discussed earlier.

Method 2: Use Disk Cleanup

When you uninstall software or drivers, they often leave behind broken registry entries. These unnecessary files accumulate over time and slow down your computer, affecting its performance. Hence, it's essential to clean up the junk that might be causing your device to run slowly.

For this reason, Microsoft added the Disk Cleanup feature to all versions of Windows. With Disk Cleanup, you can quickly get rid of unnecessary files, including corrupted registry entries. Here's how:

Step 1: Search for "Disk Cleanup" in the search bar, then select the app.

Step 2: Select the disk you want to clean up and click "OK".

Step 3: You'll now see a list of all the unnecessary files that can be deleted to free up space.

Step 4: Next, click on the Free up system files button and select the disk for a deeper system scan.

Step 5: Select the drive you want to clean again.

Step 6: The scan may take a few minutes. When it's done, check the files you want to delete in the Files section and click OK.

Step 7: Click the Delete File button to confirm.

Now you have to restart your computer in order to delete all unnecessary registry entries.

Method 3: Run Windows Startup Repair

"Startup Repair" or "Automatic Repair" is a built-in recovery tool in the Windows system. It's an ideal solution for fixing corrupted registry entries in Windows 11. Here's how it works:

Step 1: Right-click the Start button and select Settings.

Step 2: Click on “System”, and then hit the “Recovery” option from the right panel.

Step 3: Click the Restart now button.

Step 4: Your system should now boot into the Windows Recovery Environment (WinRE). This environment will help you fix common startup issues.

Step 5: Click Troubleshoot > Advanced options > Startup Repair.

Select the Troubleshoot option:

Step 6: The System Repair Tool will now scan and fix your registry errors.

Method 4: Run the DISM tool

When the SFC scan fails to fix corrupted registry entries on Windows 11, you can use DISM or Deployment Image Servicing and Management scan.

This is a command-line scanner, so open the Command Prompt like you did in Method 1. Next, type in the following command and press Enter:

The translation of "DISM /Online /Cleanup-Image /ScanHealth" in Mandarin Chinese is: "DISM 在线 / 清理映像 / 扫描健康状况"

Wait a few minutes for the scan to complete, and then check if the issue has been resolved. If not, you can try using the command below:

The American English translation of "DISM /Online /Cleanup-Image /RestoreHealth" is "Using DISM online to clean up the image and restore its health." This command is utilized to fix system files in Windows.

Method 5: Restore a backup of the Registry file

Here, you can restore the registry file you backed up while installing Windows 11 anytime to fix corrupted items. It's also recommended to back up the registry before making significant changes to your computer.

To back up the Windows 11 Registry, follow these steps:

Step 1: Press the Windows + R keys on your keyboard to open the Run box, type regedit, and then press Enter.

Step 2: If the User Account Control prompt appears, click Yes.

Step 3: Right-click on "Computer" in the left pane, and select Export.

Step 4: Name your backup file and choose a location to save it.

Step 5: Just click Save to back up your registry item.

To restore registry keys before they become corrupted, follow these steps:

Step 1: Open the Run dialog box, type regedit, and press Enter.

Step 2: If the User Account Control dialog appears, click Yes.

Step 3: Click "File" on the menu bar, and then click "Import."

Step 4: Select the Registry backup you want to restore, and click Open.

Additional Tip: Optimize Disk Performance in Windows 11

This extra tip focuses on optimizing disk performance. After implementing the methods above, it's great to see your device performing even better. By using third-party tools like Partition Master, you can effectively enhance disk performance and rid your system of unnecessary corrupted registry files.
