Windows – Disable Windows Firewall Without Admin Rights

This is not possible in the default configuration. Windows Firewall requires elevated permissions to reconfigure its settings. The MMC snap-in shows an "access denied" error, while the control panel version won't let you do anything interesting without elevating first. Starting, stopping, or reconfiguring the Windows Firewall service also requires administrator permissions. This makes sense: since the firewall settings affect everyone on the machine, unprivileged users should not be able to mess with them and thereby affect people other than themselves.

Please see your administrator and ask them to make the change you need. If you have physical access to the computer, you can see What can I do if I forgot my Windows password? to reset a given account's password, but please keep in mind that making unauthorized changes to computers is inadvisable personally even if possible technically. I recommend doing that only if you are rightfully the administrator but have lost your password.
