Restore WindowsApps permissionss to TrustedInstaller

Hi Sakso,

This Windows apps permission could have happened due to the corrupted or outdated Windows component,
we suggest that you follow the instructions below to restore or reset the default permission for your folder or file:

• Open the File Explorer.
• Browse to the system file you previously changed ownership.
• Right-click the file, and select Properties.
• Click on the Security tab.
• Click the Advanced button.
• On the "Advanced Security Settings" page, click the Change link on Owner.
• On the "Select User or Group" page, type the following to add the TrustedInstaller account and click
  Check Names: NTService\TrustedInstaller.
• Click OK and click Apply.
• Click OK again to complete the task.

Update us with the result so we can further assist you.

 

Stored files in Hard Drive

You can use Windows search. Just search for *.* on a desired drive. When list is done just arrange them by size LOL.

You can do it via command line as well and make an output text file showing files and their sizes (but without arrangement)

 

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?
