If you were prompt by Windows that you are not permitted to access Registry Editor, its mean the regedit has been disabled. It may be disabled by your administrator or if you are the only user, disabled by malware who don’t want you to remove them by regedit.
Follow the following steps…
1. Go to Start -> Run and type gpedit.msc. This will open Group Policy Windows.

3. Select "Disabled" under Setting Tab and Click Apply and then OK.
4. Now try to open Registry Edit & it will appear.
