    How Restore “TrustedInstaller” as Default Owner of a File

    I took ownership of C:/ as an administrator. I was not suppose to.

    I tried following the step given but cannot do some of the steps because I don't have it.
    How do I give permissions back to TrustedInstaller, when I changed ownership, I don't have TrustedInstaller in the list of possible owners anymore in C drive
    My Windows 8 don't have some the steps mentioned

    The following are the steps I follow:
    1 . Go to the folder which contains the file or folder for which you want to restore ownership to "TrustedInstaller". Right-click on the file or folder and select Properties.
    I right click on os (c ) and selected properties
    2. It'll open its Properties window. Now go to "Security" tab and click on Advanced button
    I clicked on security
    object name c:\ ( the tutorial has shell32.dll properties windows mine is blank)
    3 . It'll open a new window. Now go to "Owner" tab and you'll see that the owner would be set to your username and "TrustedInstaller" would not be present in the list as we mentioned above.
    I don't have this
    object name: c:\windows\ system32\ shell32.dll I don't have this
    4. It'll open another window. Click on "Other users or groups" button.
    5. Now type NT SERVICE\TrustedInstaller in "Enter the object name to select" text box and click on OK button as shown in following screenshot:
    NT SERVICE\TrustedInstaller

    Systems: windows 8

    properties > security
    object name: c:\
    Group or user name
    I don't have TrustedInstaller listed

    > Advanced
    Advanced security setting os(c
    name c:\
    Owner me change

    step 3: advanced security setting is different than tutorial. I don't have "owner" to click on

    When I click on "change" in owner
    select user or group windows popup
    object name : NT SERVICE\TrustedInstaller
    When I click on check name I got the following message
    named not found

    When I did the following properties> security> edit > add
    object: NT SERVICE\TrustedInstaller
    click ok, I got the following message from window security
    I click yes I got the follwing message: error applying security
    an error occur while applying security information to
    failed to enumerate object in the container access denied
