A whole year? Wow.

First thing I'd do is run a full anti-malware scan with free Malwarebytes.

Malwarebytes : Malwarebytes Anti-Malware PRO removes malware including viruses, spyware, worms and trojans, plus it protects your computer

I'd next run a System File Checker scan to make sure you don't have any damaged or corrupt system files. Run teh scan from an elevated command prompt (option two, this tutorial.) If any problems are found, run the scan three times rebooting in between each scan.

SFC /SCANNOW Command - System File Checker

See if the firewall can be used. If not, try Methods 2 and 3 in this Microsoft article.

Please post back if any of this helped or not.

Are you using another free firewall like ZoneAlarm, Outpost, Comodo, Online Armor, etc or an antivirus suite that includes a firewall? If yes they will disable the Windows Firewall.
