If you’re running Windows 7 or higher, you’ll be able to take advantage of a free upgrade offer to Windows 10 from Microsoft. Look for the upgrade through your regular Windows Update utility.
Available in several versions that roughly correspond to current Windows offerings, Windows 10 will add some familiar operational features back to the current Windows 8.1 experience, plus add a range of neat new security and productivity solutions.
One of our favorite new security features is Windows Hello. Using camera technology, infrared lasers, multiple lenses, and a special processing chip, machines with this new technology will be able to work with Windows to authenticate users visually. Coupled with some other technologies in Windows 10 like Microsoft Passport, the end will be in sight for old-fashioned and vulnerable passwords.
