By default, almost all system files, system folders and even Registry keys in Windows 10 are owned by a special built-in user account called "TrustedInstaller". So, once you take ownership and grant admin permissions to a file oe folder, and later want to restore the TrustedInstaller account as the owner, you will notice that it is not shown in the list of accounts. Here is how to restore the TrustedInstaller ownership in Windows 10.
To restore the TrustedInstaller ownership in Windows 10, do the following:
- Open File Explorer, and then locate the file or folder you want to take ownership of.
- Right-click the file or folder, click Properties, and then click the Security tab.
- Click the Advanced button. The "Advanced Security Settings" window will appear. Here you need to change the Owner of the key.
Click the Change link next to the "Owner:" label
- The Select User or Group window will appear.Type here "NT Service\TrustedInstaller" as the new owner name:
- Click OK to change the ownership.
You are done.
Also, you may want to add a special context menu to File Explorer to save your time.

You can save significant amount of time by adding the Change owner command to the right-click context menu in File Explorer.
