Permissions problems accessing windows settings

For a couple months already I have been unable to access basic settings trough windows, like troubleshooting an Ethernet or accessing Advanced display settings, every attempt has led me to an error (see attachment bellow) telling me I do not have the right permissions, the cause to this is to me most likely linked to TrustedInstaller, now I changed the owner of the disk, windows folder, system32 folder to administrator and removed trusted installer, but it never worked, not even removing trusted installer and giving administrators full control over the specific files did the trick. Being locked away from most of window's advanced settings has been really crippling and so far nothing I have seen on the internet has been really helpful, any ideas? Thanks in advance! I added a couple attachments to some errors I came across browsing the settings.

You can use Windows Repair utility to reset file permissions.

If Windows Repair utility wont resolve the permission error you can repair install Windows 10.

I have intentionally locked the following file via NSudoC, which is necessary for unlocking it.



Has anyone who has access to the OP's PC locked the files intentionally?

I am the only one who has access to this PC so I don't think that would be possible

It might be possible to unlock the file via PowerRun. Do you want to give it a go?

I know how it works. We can try it out if you are interested.

Sure thing!

PowerRun might be unneeded. Please click here to download "Unlock_files.zip".
Extract "Unlock_files.cmd" from the .zip file and double-click to run it.
Hopefully, the .cmd file can restore the default permissions to the following files:

C:\Windows\System32\rundll32.exe
C:\Windows\System32\control.exe
