<b>Windows 7: Microsoft gets it right</b>
<b>Release date: Oct. 22, 2009</b>
With Windows 7, Microsoft seems to have nailed it. Two-hundred-forty-million licenses were sold in the first year of availability, making it the fastest selling OS in history. Although Windows XP still has the highest market share, Windows 7 has already surpassed Vista and IT pros surveyed by Forrester Research say that within one year 83% of new corporate PCs will be powered by Windows 7. Windows 7 has been described by reviewers as more user-friendly than Vista, and perhaps more secure with new features such as AppLocker to control which applications run on a corporate network, BitLocker To Go, which encrypts USB flash drives and portable storage devices, and wider use of fingerprint logins. It's available in 32-bit and 64-bit versions.
