It does not matter much if you tick or untick bitsadmin.exe, because this firewall rule cannot prevent the download initiated by bitsadmin.exe via malicious scripts, and cannot also create problems with Windows Updates. The executable bitsadmin.exe initiates the download via svchost.exe and BITS, so firewall can see/block only svchost.exe. The firewall rule for bitsadmin.exe can only work, when the malicious code is injected to bitsadmin.exe, and this malicious code wants to use the Internet connection in another way than BITS. But, using bitsadmin.exe in this way would be rather improbable.For Windows Firewall rules leave bitsadmin and lsass.exe unticked, this can create problems with certain VPNs and Windows Update. Hopefully these SS's will help you going forward into what you need to do for Syshardener.
How can I reset all settings? I tried 'System Restore' but it fails.
I pressed 'Select All' --> 'Restore Selected'. That worked fine, seems like everything is back in normal. Will this work too or did I mess something up?
You might have to do it again, in all the user accounts to which you applied your settings, because some of the settings are user-account-specific.I pressed 'Select All' --> 'Restore Selected'. That worked fine, seems like everything is back in normal. Will this work too or did I mess something up?
This is the correct way to restore Windows default settings, as explained in FAQ. Very simple. You should have no problems.
