A lot of users face this error on almost all the versions of the Windows OS when they want to change system files or gain full control of another account’s files. This error is primarily prompted when you try to access/modify a file which doesn’t come under your authorization. This error can pop up on a number of events. You might want to access old files from an older account or you might want to configure some system files present in local disk C.
If you don’t have specific permission, Windows will deny you access indefinitely. IF your account has administrative privileges, you can gain access to the file by changing the ownership. You can change the ownership of any file/folder through the GUI.
Method 1: Changing ownership through GUI
This is the easier method and may suit most of the people in taking ownership of any file or folder. However, if you want to go with changing the registry, you can refer to the second method explained below.

- Now we need to grant your account full access. Right click on the file/folder and click on Properties from the list of options.
- Navigate to the Security tab so we can access the NTFS permissions.
- Click on the Advanced
- Now you will see all the permissions listed regarding each account in front of you. Under the Permission tab, click on Add.
- Now you should click on Select a Principal so we can add your account.
