Today I've changed permissions for the registry key HKLM\SYSTEM\CurrentControlSet\Services\SharedAccess (under which FirewallRules are stored) removing "Everyone" and "Users" in order to restrict access to the key from the account of the standard user.

When I restarted the laptop I see that Windows Firewall doesn't work at all and when I try to open its "Advanced settings" I see the error on the screenshot

enter image description here

Is it possible to fix the problem without re-installing Windows?

  • Why can't you redo the deleted permissions?

To redo the permissions of SharedAccess, from my Windows 10 :

  • users has only the Read permissions
  • everyone is not present at all, and probably only required for access from the local network. If you would like to restore it, give it also the Read permission.
  • It's Windows 7, as specified in the title and the tag

  • It shouldn't be much different and can serve as a starting point.

  • The problem is, I removed "Everyone" at all from the key SharedAccess, not just permissions for it

  • No problem - use the Add button, type everyone, click Check Names, click OK, click Read (below), click OK.

  • I did as you described and restarted computer, but that didn't help. I also tried all 4 solutions described by the link, but still without success...
