If you encounter an error saying, “error accessing the registry” when you try to merge a registry key on your Windows 10 computer, you’re not alone as some users also experienced the same problem. According to these users, they encounter the error after they’ve re-installed their Windows version and tried to open a .reg file.
Based on the reports, this error could occur if the registry file does not have administrative privileges. Meaning to say, the program does not have the necessary permission to merge the .reg file. This is common with fresh installs as well as reinstalls. Moreover, this kind of issue could also occur due to system file corruption. Whichever the case may be, here are some troubleshooting tips you can check out to resolve the error.
As pointed out, the error may be due to a lack of admin privileges. It could be that the Registry Editor does not have admin privileges to merge the registry file. This is common with new Windows installations especially since the Registry Editor hasn’t been opened before. So you need to import the .reg file again and this time, with admin privileges.
Running System Restore can also help you fix the error when accessing the Registry. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.
As mentioned, the error when accessing the Registry might be caused by file corruption. And that’s where the SFC scan comes in. The SFC or System File Checker scan could detect and automatically repair damaged system files. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
