    Unable to change Admin Settings

    I am having issues writing to C or modifying files on the C Drive.

    I read that I should explicitly add myself (named) as a user in the security settings, which I have done.

    When I try to apply the settings, I get the following message for most of the folders in C

    I also get the following error if I try to create a .txt file at the route of the C drive.

    Unfortunately, the 'Take Control' tool doesnt work either, I get the following error code:

    Error 0x80070522: A required privilege is not held by the client.

    okay, so I tried something else, seems to be updating each file on C:, which so far other methods have thrown an access error.

    If you go to C: and right click. Select Properties > Security and then click 'Advanced'

    You will see the 'Advanced Security Settings for OS (C:) window.

    In there, at the top, check the 'Owner:' property is set to you, mine was set at "Trusted Installer".

    Click 'Change', type your username and click 'Check Name' then Update.

    I will update on if this was successful once mine has all updated.
