Windows - settings are controlled by group policy - help
The fix that worked for me was to rename my original computer administrator the name the computer was given at firs set up.
1-click on start, 2-select control panel, 3-go to user names, 4-go to change a name and rename the computer administrator the original name that it was when first installed. You may have gotten your computer used, you have to name the admin the name that it used to be and firewall will return to normal. Hope this helps, it is what finally worked for me.
