The Registry is a database that stores Windows operating system and application settings. Sometimes, you need to change those values manually. ‘Can’t edit Registry‘ is an error you’ll face when you try to edit a key in Registry but you don’t have the necessary permissions to do it.
How to edit any Registry key
You can start editing any Registry key you want by gaining the permission to do it. Before you follow the step-by-step guide to gain permission, you should know that editing the Registry is a very dangerous thing to do.
If you edit it without knowing specifically what to do, you can break your computer. You must make sure to create a restore point, backup your Registry, and edit with extreme caution.
Fix ‘Can’t edit Registry’ through Advanced Security Settings
You can change the owner of the Registry keys or folder to yourself. This will give you control to edit, delete, or insert keys in the folder. The only downfall of this method is that you have to repeat the steps for each folder you want to edit. Here’s how you do it:
- Search for Regedit in Start and right-click on it, and from the menu, you should click on Run as administrator.
- Navigate to the folder you want to edit.
- Right-click on the folder and then click on Permissions.
- The Permissions window will open, click on the Advanced button near the bottom-right corner.
- The Advanced Security Settings will open. At the top of the window, you’ll see, “Owner: [name]”, where [name] is most likely the name of the program that created the folder. Click on the Change Link.
- In the Select User or Group form, under Enter the object name to select, prove your username on that computer or your Microsoft email address if it is associated with your computer. You then have to click on Check Names.
- Click OK both on the Select User or Group window and the Advanced Security Settings window.
- Before closing the Permissions Window, select Users from the Group or user names list and check the box under allow for Full Control. After that, close the window by clicking OK.
