Broken registry items don’t usually cause PCs to be nonfunctional, but when the registry grows bigger and older with time, it can have lots of corrupted or broken items. And that’s where the problem starts. 

Your PC slows down, lags and freezes occur frequently, and programs and apps might crash. This is not a fun thing to experience. So, in this guide, we’ll show you how to fix broken registry items on your Windows 10 or 11 PC. 

Let’s start, shall we?

What Are Broken Registry Items?

Broken registry items are corrupted, invalid, or leftover entries in the Windows registry. These entries become “broken” when they no longer point to valid files or settings because of issues, like software you’ve uninstalled or updated, malware, sudden system crashes, etc.

What is the Windows registry and why is it important?

The Windows registry is a database that stores low-level settings for your operating system and applications. Think of it as the brain of your PC. It keeps track of essential configurations, such as user profiles, system hardware, and installed software.

When the registry is functioning properly, it ensures your system operates smoothly. However, when it contains broken or corrupted entries, it can disrupt performance, causing lags, crashes, or even system errors. 

That’s why keeping the registry clean and repairing broken items is crucial for maintaining a fast, stable, and reliable PC.

Causes of Broken Registry Items on Windows 10/11

Let’s go through the reasons why broken registry items occur:

Effects of viruses and malware

 Malware and viruses can cause serious problems with the registry by leaving behind traces that continue to cause slowdowns and error messages even after removal. Some viruses specifically target and modify the system registry, leading to various issues within it. 

You can remove the malware, but keep in mind that if this is the cause, the damage is already done. Once the malware is removed, you’ll have to implement the solutions we’ve covered in this article to permanently fix the problem.

The registry is fragmented

Registry fragments are obsolete entries that remain after changes to the system. This issue can happen when: 

  • Uninstalling a software 

When you delete a software, ideally, all the files and registry entries associated with it should be removed. However, sometimes, these residuals are left behind and become orphaned entries (they no longer have a corresponding program or service related to it), also called “leftovers.” Over time, these leftovers can clutter the registry and lead to fragmentation. 

  • Upgrading a software

When you upgrade a program, you install a newer version over an older one. This process can cause registry issues because new installation might create new registry keys while old ones remain, resulting in duplicate keys. Besides that, sometimes new software versions make changes that are incompatible with older entries, causing the registry to become fragmented.

  • Updating a software

When you update a software, which basically means applying patches or minor improvements, the process is similar to upgrading but on a smaller scale. But here’s the problem. Sometimes, updates don’t fully replace old registry keys; instead, they add new entries, and this can lead to inconsistencies. 

Also, updates can cause conflicts if the new information doesn’t align well with the existing registry settings. All these can cause fragmentation, and in severe cases, lead to broken registry items if certain keys don’t function anymore or are causing errors.

Problems with system shutdown

The system memory stores a copy of the registry every time your computer shuts down. But if your PC turns off suddenly, like after a sudden power outage or a crash, this process can be interrupted. When this happens, it can corrupt the registry files because the information stored in those files becomes damaged or unreadable. 

When the computer tries to read the corrupted registry files the next time it starts up, it might encounter broken items, which can prevent it from working properly.

Method 1: Check for malware on your PC

Before you begin the steps to curb the corrupted registry items, scan your system to see if it’s infected with malware. As I already said, this won’t fix the problem, but it’ll remove the root cause of the issue.

After, you can implement the subsequent steps to resolve the issue. If you’re sure that your PC isn’t infected with malware, skip to the next method.

With that said, here’s how to scan for malware using Microsoft Defender:

  • Type Windows Security in the search bar and click the best match to open the app. 
Type Windows Security in the search bar and click the best match to open the app
  • Click Virus & threat protection and select Scan options.
Click Virus & threat protection and select Scan options
  • Click on Microsoft Defender Antivirus (offline scan) and then Scan now.
Click on Microsoft Defender Antivirus (offline scan) and then Scan now

Windows Security will perform a deep scan of all the system files using the latest protection updates. However, it won’t hurt to check for Windows updates manually as well prior to the scan to ensure optimal protection.

After the scan, restart your computer and check whether the issue has been fixed.

PRO TIP
You can scan your PC for potential malware using Auslogics Anti-Malware . It complements your main antivirus by thoroughly scanning your system for various threats, such as malware, spyware, Trojans, etc., using advanced algorithms and deep scanning techniques.

Think of it as an extra layer of protection. Anti-Malware monitors your computer in real time, detects possible attacks, and stops them before they can infiltrate and do damage.

Method 2: Use System Restore

One effective way to delete broken entries in the Windows registry is to use System Restore. This will revert your system’s registry to a moment when it wasn’t corrupted.

When important changes are made to your system, such as installing new software or drivers, Windows automatically creates restore points if you’ve already enabled the System Restore feature.  

You can also create the restore points manually.

This method will only work if the system or you have already created a restore point. If you haven’t, move on to the next step.

Go through the steps below:

  • Type control panel in the search bar and click the best match.
  • Click Category beside View by and select Large icons or Small icons.
Click Category beside View by and select Large icons or Small icons
  • Select Recovery.
Select Recovery
  • Click Open System Restore.
Click Open System Restore
  • Click Next to continue in the window that pops open. Then, select your preferred restore point from the list. 
Click Next to continue in the window that pops open
  • Select Scan for affected programs to check the list of drivers and programs that will be affected by the restore. Click Close to continue if you’re OK with it. After, click Next.
Select Scan for affected programs to check the list of drivers and programs that will be affected by the restore

Check the information carefully before clicking Finish.

The system restore process will start and can take a while to complete. Your computer will restart when the restore process is finished. Your system will be returned to a previous state where your registry was whole and undamaged.

Method 3: Use Windows Disk Cleanup

When you uninstall drivers and software, they usually leave behind broken registry items. Over time, these invalid registry files build up, clutter your computer, and eventually affect its performance.

Luckily, you can use Disk Cleanup to correct this problem. Go through the below steps:

  • Type Disk Cleanup in the search bar and click the best match.
Type Disk Cleanup in the search bar and click the best match
  • Select the drive you want to clean up and click OK.
  • You’ll see unnecessary files you can delete. Click on Clean up system files and select the drive to run a detailed scan. 
Click on Clean up system files and select the drive to run a detailed scan
  • Tick the files you want to delete under the Files to delete section and press OK.
  • Click on Delete Files to confirm.

After everything, restart your computer and check to see if the problem has been resolved.

Why deleting programs properly is really important

When you uninstall a program, it’s not just about removing the visible files. Each program you install creates entries in the Windows registry to store settings and configuration data. If you don’t delete a program the right way, like by simply deleting its folder, those registry entries can be left behind.

These leftover entries can accumulate over time in your registry, leading to broken registry items. This can slow down your PC, cause errors, and make your system less reliable. 

That’s why it’s important to use proper uninstallation methods, like dedicated removal tools, to ensure both the files and registry entries are removed without leaving anything behind.

Method 5: Use the System File Checker tool

Another way to fix broken registry items  is by using SFC. You can do this using the Command Prompt.

The purpose of the SFC command is to check the system file directory for any corrupted or missing files. And when it finds one, it fixes it. Here’s how you can use SFC to delete broken registry issues:

  • Type command prompt in the search bar. 
  • In the right pane, select Run as administrator.
In the right pane, select Run as administrator
  • Type the sfc /scannow command and press Enter.
Type the sfc /scannow command and press Enter

Your computer will search through all of its system files after you run this command to identify any damaged ones, including registry entries. The process often takes at least 30 minutes to complete.

Don’t worry if after running the SFC command you still get a notice saying, “Windows Resource Protection found corrupt files but was unable to fix some of them.” This message means that SFC identified some corrupted system files but couldn’t fix them automatically. Proceed with the next solution.

Method 6: Run Automatic Repair

The Automatic Repair tool can fix system boot issues and core system registry files. Here’s how it works:

  • Go to Settings, click on System, scroll down, and select Recovery

The utility will check your system and repair any registry issues. After that, restart your computer.

Method 7: Import a registry backup

If you regularly create registry backups, you could use an old backup to fix any registry issues.

This method only works if you already have a registry backup. If you don’t, move to the next solution, but keep in mind that it’s essential to get into the habit of backing up your registry. The Windows registry is a critical component of your PC, so making changes to it, whether manually or through automated tools, can be risky. 

A small mistake or unexpected issue can lead to system instability or crashes. So, a simple precaution such as backing it up can save you from bigger headaches down the road!

Here’s how to do it: 

Type registry editor in the search bar and click the best match
  • Click on File and select Import.
Click on File and select Import
  • Search for the registry backup file and click on it.
  • Wait for the system to restore the registry.

Method 8: Manually fix registry errors through the DISM command

DISM (Deployment Image Servicing and Management) can inspect and correct problems with the Windows system image file. During its operation, DISM fixes issues with your computer’s system files, which can help resolve related registry issues, as they depend on each other to function correctly.

Here’s how to run the DISM scan:

  • Type command prompt in the search bar. Select Run as administrator in the right pane.
  • When the Command Prompt window opens, enter DISM /Online /Cleanup-Image /ScanHealth and press Enter.

Method 9: Reset the Windows system

You can reset your computer using the Windows Reset function. This feature allows you to reinstall Windows, giving your system a fresh start.

This process can help fix broken registry items because resetting the PC removes all existing system files and registry entries and replaces them with new, clean copies.

It also restores your computer to its default settings, which means any problematic changes made to the registry over time are wiped out.

Don’t forget to back up all your files before resetting the PC.

Here’s how to do it: 

  • Press Windows logo + I to open the Settings window.
  • Search for Recovery and click on it. 
Search for Recovery and click on it
