If you can't open Registry Editor on Windows 10 computer, a dialog box will show up, with a message explaining that registry editing has been disabled by the administrator, as exhibited in the following picture. FYI, such a problem can be worked out easily by adopting the method illustrated below.

What does this message mean? It usually means either: A group policy has disabled it; The registry key controlling access has been set; Or a malicious tweak (or malware) caused the change. Here's how to fix it safely.

Method 1: Use Local Group Policy Editor (Pro / Enterprise / Education)

Step 1: Start the Local Group Policy Editor.

Step 2: Find and open the setting named "Prevent access to registry editing tools".

Locate the setting in User Configuration/Administrative Templates/System, and then double-click it.

Step 3: Disable or do not configure this setting.

In the setting's window, select Disabled or Not Configured, and click OK.

Method 2: Modify the Registry Key Directly (All editions)

You can run Command Prompt (Admin) or PowerShell (Admin). Then execute this command to set the disabling flag to zero:

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f

Method 3: Unblock After Malware or Shell Hijack

Sometimes malware creates a fake regedit.com to override regedit.exe. You need to check C:\Windows or C:\Windows\System32 for suspicious .com files. Besides, use your antivirus or full antivirus scan.
