Microsoft has said you will no longer need any anti-virus software because Windows will be fully protected against all viruses, and presumably any other hack attacks. If you believe that, Bob wants you to know that he has a large bridge in New York that he’d like to sell you. (No new operating system ever produced has been invulnerable to virus attacks.)
Nevertheless, Joy, our master tester, likes Windows 10, saying it has the best of Windows 7 and avoids the worst of Windows 8. (Bob is sticking with Windows 7. He grudgingly went on from XP after his old computer got balky.)
If you want Windows 10, beware of scams. There are sites that lure visitors with the promise of a free copy. It’s already free, but be sure you get it from Microsoft.com. The exact address is Microsoft.com/en-us/software-download/windows10. Click on “download tool now.” If you aren’t sure whether you have a 32-bit system or 64-bit, you can find that by searching on “system info” from the help area of your computer. Just hit the “F1″ key to bring up a help menu. If you still can’t decide, it’s almost certain that you have a 64-bit system; we haven’t seen 32-bit systems in many years.
