    TrustedInstaller deleted


    Hi all.

    Newbie here. I've made a grave mistake by deleting "TrustedInstaller".
    Before that I've took over the permissions of my C:\ OS drive and gave them to my only Administrator account.
    Now I can't open C:\ drive, install any programs besides Google Chrome by some reason.
    Already tried restoring system from a backup date 2 times. It didn't help. First time before 3 days ago, next time from a month ago. I've used the Reset option of Windows to get back to manufacturer settings. Nothing.
    Tried to add back "TrustedInstaller" to the list of Advanced Security Settings of drive C:\ by "NT Service\TrustedInstaller".
    Doesn't help. Same error as every time. Acces for all the accounts is disabled. Windows Troubleshooter also not responsive cause of the permissions. Basicly most of the things I'm trying to do I'm not being allowed to.
    Any help will be appreciated. I know I've screwed up. Is there still anything I can do instead of clean install?


    Microsoft Windows version 20H2 (OS build 19042.630)

    Trustedinstall & updates 30% & cannot delete partion

    Hi all,

    needed help from my friends windows problem.

    what i found out his issues on windows keep restart after windows update at 30% because before restart pc he had uninstall the IE or defender.

    so i took out his nvme and install to my PC reason being i cant access to safemode.

    first i was knowing the nvme of his were brand new and no bad sector and all.

    when i try to delete files it show warning massage regards i cannot move or delete and i guess i also cannot reformat windows too due trustedinstaller problem.

    using disk management to format or remove or convert to dynamic disk it shows warning the I/O failing massage.

    try many method of convert mgr to GPT still not working,

    CMD method : some times it show i success format or able to delete partition and all. i reopen disk management. the files and still remain the same.

    i follow a few step using the third party app like takeowner still not working.

    i had follow below step:

    Restore the TrustedInstaller ownership in Windows 10

    but at this step 4 The Select User or Group window will appear.Type here "NT Service\TrustedInstaller" as the new owner name:

    saw many onlines using different user and group (i had confuse on this part if i am not using NT Service\TrustedInstaller i unable to proceed next step )

    once i done this i finally able to copy windows folders for testing but i cant delete.

    is there any simple way i able to FORMAT whole thing instead go though all these.

    thank you~~~
