Although Windows 7 has just been released, it does not mean that you can not find free utilities to tweak your system, add features or software that will help you upgrade smoothly from Windows XP product key or Windows 7 Vista.
Microsoft Security Essentials
Like its predecessor, Windows 7 is not equipped with anti-malware tools like viruses and spyware. You can pay for the services of McAfee or Symantec, but why bother with this when Microsoft Security Essentials provides solid protection for your home computer, and it's free. If you prefer third-party security software, you can also use AVG Anti-Virus Free Edition instead.
Ninite
