Registry Editor plays a vital role in addressing numerous issues that occur from time to time on Windows 11 or 10 PC. However, what if it has become corrupted, and when you are trying to start Regedit, you get an error message – “Registry Editor not opening”. Since you are here, you must be looking for answers to this problem.
Well, you’re gonna as in this post, we discuss what may cause this issue along with three workarounds to this trouble. Let’s have a look at the reasons and solutions in somewhat more detail –
What causes the “Registry Editor not Opening” issue on Windows?
Registry stops working or simply doesn’t start when called upon only if it contains a subkey that has a length size of 255 bytes or more. There is a possibility that you had accidentally created such a long subkey on your computer. However, most of the time, it happens because of the presence of infected files, viruses, or malware.
Now that you know what exactly had caused this issue, let’s have a look at fixes that should resolve this issue on your Windows 11 PC.
4 Easy Ways to Clean Registry in Windows 11
Fix – Registry Editor has stopped working
To fix the “Registry Editor not opening” issue on Windows 11/10 PC, try out these two solutions and see which one exactly resolves this trouble.
1] Rename Regedit.exe
As stated above, the registry editor won’t open only when there is some issue within it. If you had created a registry backup sometime back on your computer, it’s the perfect time to use that. However, if you had never created such a backup, rename regedit.exe and see if it works. Here’s what you need to do to rename the registry application on Windows PC –
- Click the File Explorer icon available on the system tray (taskbar).
- On the left navigation, click This PC and browse to the below location –
C:\Windows\System32
- Press Ctrl + F, and type “regedit.exe” in the text field.
- Press the Enter key to begin searching for the matching result.
- When found, right-click on it and hit the “Copy” button on the context menu.
- Browse to somewhere safe on your PC and paste the copied item there. By safe, we mean a place the files don’t get deleted accidentally.
- Right-click again on this file and this time choose the option – “Rename”.
- Rename it to something like – “
Newregedit.exe“ - Right-click again on this file and hit – “Run as administrator”.
The registry editor should start without any issue. If not, try the next workaround –
2] Run SFC and DISM Scans
If the above fix doesn’t resolve the “Registry Editor not opening” issue, there must be corrupted files or folders on your PC. Try SFC and DISM tools to find out where the corruption lies on your computer. Here’s how to run both these tools together on an elevated console –
- Press Win + R to launch Run.
- Type “CMD” and press Ctrl + Shift + Enter keys altogether.
- Performing so will launch Command Prompt as an administrator.
- Copy/paste the below code and press Enter –
sfc /scannow
- System File Checker will then diagnose and repair the files that it finds damaged. This tool will even re-generate the missing files on your device.
- Once this is over (reaches 100%), execute the below command –
DISM.exe /Online /Cleanup-image /Restorehealth
- This tool will look for any corruption inside the system image and repair that.
- After this scan reaches 100%, you may close Command Prompt and restart your PC.
Sign back into your computer and check if the issue has been resolved.
3] Use a previously created Restore Point
In case your device does have a restore point created sometime back, you may use that and see if the problem resolves.
Trying a system backup will revert back your PC to an earlier state where everything was running perfectly. I hope this problem resolves automatically when your device wakes up.
That would be all.

The Windows 10 Registry is a database used by the operating system to store configuration settings for native programs, installed software, and hardware devices.
It serves as a central repository, making it a critical component for Windows 10. But what happens when things go wrong?
The built-in editor, known as Registry Editor, provides a graphical interface for browsing the Registry and editing its values and keys. You can fix errors and make changes that are not available through the regular Windows interface.
However, when Windows is significantly damaged even this can crash or fail to open at all. Common error messages include:
- The Registry Editor has stopped working.
- Registry editing has been disabled by your administrator.
Why does the Windows 10 Registry Editor stop working?
Registry Editor can stop working for many reasons. The most common causes include:
- Hardware issues – Issues with the hardware, such as hard drive failure or RAM problems can stop the registry editor from opening or freezing while in use.
- Issues with Windows Updates – If your PC crashes while updating Windows or the update is otherwise corrupted, this can damage the registry editor and other system files.
- Insufficient permissions – If you don’t have sufficient permissions to access the Registry Editor, the editor will not open.
- Group policy has been disabled – The Local Group Policy is a series of system settings that includes access to the registry editor. This might have accidentally been disabled.
- Malware – Some malware and viruses shut down access to important areas of Windows to prevent you from fixing it. The registry can be one such target.
- Broken Registry – When the Registry itself is significantly damaged, the editor may not work properly or fail to load altogether.
How do I fix the Windows 10 Registry Editor?
The fix you use to repair the registry editor in Windows 10 may depend on the cause. Here are the best solutions:
1. Use Administrator Permissions
If you are getting permissions errors, the obvious solution is to run the registry editor as an admin. To do this, either:
- Log out of Windows and log back in with the administrator account.
- Type regedit into the Windows search box, then right-click the Registry Editor app and select Run as administrator.
2. Enable the Group Policy
- Press the Windows + R keys on your keyboard to open Run.
- Type gpedit.msc and press OK to open the Local Group Policy Editor.
- Go to User Configuration, then select Administrative Templates, and click on System.
- Open the Prevent access to registry editing tools setting on the right.
- Select the Disabled or Not configured option to turn off the prevention.
You may need to restart your computer for this to take effect.
3. Edit the Registry using Command Prompt
- Use the Windows Search box and type cmd.
- Right-click on the Command Prompt app and launch it as Administrator.
- Type the following command and press Enter to run it: REG add HKCUSoftwareMicrosoftWindowsCurrentVersionPoliciesSystem/ vDisableRegistryTools /t REG_DWORD /d 0 /f
- Restart your computer.
If the registry is damaged, the key to use the editor may have been deleted. You can enable it using the Command Prompt.
4. Check the system files
- Use the Windows Search box and type cmd.
- Right-click on the Command Prompt app and launch as Administrator.
- Type the following command and press the Enter key to run it: sfc /scannow
- Wait for the process to complete then restart your PC.
When Windows system files that affect the registry are damaged, you can attempt to repair them using the System File Checker.
5. Perform a System Restore
- Use the Windows Search box, type Restore and click on Create a restore point from the results.
- Click on System Restore, then hit Next if you want to use the recommended restore point, or select the option below to Choose a different restore point.
- If you use the latter, choose a date when you know the registry editor was working and go through with the restauration.
If you cannot seem to repair Windows and you do not know what’s causing the problem, a System Restore can help. This rolls back all system settings and configurations to a previous point in time.
However, for this to work you must have already made a restore point.

When the Registry Editor stops working in Windows 10, it often signals damage to the registry itself. Fortunately, there are several fixes to get things running again. In some cases, you simply haven’t enabled the right permissions.
Registry Editor crash occurs upon launch, while changing permissions of subkeys, finding information into string values and several other occasions.

corrupt user profile, corrupt system files, incorrect Registry settings may also cause this issue. In this case, you should scan your computer for possible Registry errors. Download and scan your computer with an efficient registry optimizer now for better computing experience.
