need help with OS drive default permissions

Hi. I completely destroyed my windows because I unchecked the box that said allow index on C drive. I think it is because many files gets access denied changing, so something breaks because of it, giving me tons of problems. Can someone take a screenshot of the permission security tab to show me if it's the same? And authenticated users have neither allow nor disallow ticked in the boxes, I don't think that's normal! Maybe that's what's breaking things. Restore point don't work because the checkbox on c drive for allow index does not change. When I use tweaking.com windows repair and take back permission on folders in C drive it fixes the issues I'm having but then at a later time it all comes back. So I need a permanent fix.

will this do the trick?
"You can run CACLS C:\*.* /C /E /R "userName":R for the root of drive C while leaving the subdirectories intact.

Or, you can run it on just the specific files instead of the entire root if you wanted to go that route."

I want to only change these permissions, because tweaking.com does programfiles and windows folder already. will this command do just that?

This is the one i want reset to default

Removing the indexing attribute on C:\ won't break any permissions.

Evidently you've done something else wrong.

This is one scenario where "sfc /scannow" and "DISM /Online /Cleanup-Image /RestoreHealth" are actually useful, since DISM knows what the original ownership/permissions were. If that doesn't work, you're looking at a repair re-install.

Hi. I have done sfc, but still I get the issue where firewall gets disabled out of nowhere. This always happened when I unchecked the index box. Always when I did this and forgot last time it broke stuff, I get the firewall is turned off notification and firewall option in Norton is off as well as the Windows firewall snap in not working, saying it's off. Then as soon as I do repair the firewall and reset file permissions in tweaking.com, it works again for a random time. So it's connected to that unchecking. The command above did not work, I got this message in cmd, "No mapping between account names and security IDs was done." i don't know why. i did write my username. Does it also have to include my computer name? Can you check the permission on C drive and check the authenticated user if you also have no check boxes on allow or deny, just like my picture?

All I can suggest is do a repair re-install from a downloaded Windows ISO, because I have no idea what you did before or whether Tweaking.com's tool made it better or worse. A repair re-install (or clean install) is the only way to get it back to a known good state.

Yes. But that's why I am here to prevent that. If anyone else can help out, thanks.

At least check what I asked garlin to check for me but did not for some reason.
