Windows 10: How to change ownership away from TrustedInstaller for Windows Defender

I don't know how to change the ownership away from Trusted Installer to Admin for Windows Defender. I right-clicked on Windows Defender folder, click on properties, clicked on Security Tab, clicked on Advanced and click on Change next to Owner. Normally a window would pop up to change the user but when I click on change change just greys out and no window opens to change the user.


Any and all help would be appreciated.

Changed the ownership of C:\windows on 2016 server from trustedinstaller to administrator and changed back

Hi Everyone,

Please help me with the following concern.

On my 2016 server i changed the ownership of C:\windows from Trustedinstaller to local administrator. I had also unknowingly selected the option to apply it to sub folders and files. Noticed it had changed ownnership on all the subfolders in C:\windows
to Administrator.

Post this i changed ownership back to Trustedinstaller, and no permissions were changed.

Now i see all folders in C:\windows , owner as Trustedinstaller. On another 2016 server i found that some subfolders have the ownership set to system in C:\windows.

Will the existing ownership of C:\windows and its subfolders to trustedinstaller cause any problem? If yes how do i reset the ownerships to defaults. There we no permissions changes done.

Thanks,

Hi Ron,


To help resolve your concern, you have to first take ownership of the files or folders and then grant yourself full
control permissions and rights. To do so, follow the steps on this link:

• 
  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 select
  Security
  tab.
  
• 
  Click the
  Advanced
  button and the
  Advanced Security Settings
  window will appear. 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 "NT Service\TrustedInstaller"
  as the new owner name.
  
• 
  Click
  OK to change the ownership and you are done.
  

Let us know how it goes.
