According to Net Applications, it's been a good month for Microsoft. Internet Explorer 8 gained more market share to continue dominating the browser market, and Windows 7 surpassed its predecessor--Windows Vista--in market share for the first time. So, what exactly is driving the success of Windows 7?
1. Management. With integrated support for PowerShell 2.0, Windows 7 provides a superior infrastructure for IT admins to be able to automate common tasks and manage the desktops more efficiently.
2. Troubleshooting. Windows 7 provides Troubleshooting Packs that enable users to conduct their own troubleshooting for many common issues. IT admins can also create custom Troubleshooting Packs for recurring issues or internal applications.
3. Security. Windows XP--which is still by far the most used operating system--is far behind Windows 7 when it comes to security controls. Windows 7 has security controls--like ASLR (address space layout randomization), DEP (data execution prevention), and UAC (user account control), and PMIE (Protected Mode IE)-- that don't exist in Windows XP.
4. It's Not Vista. The reputation of Vista is more a Microsoft marketing failure than the result of any real issues with Vista. While Windows 7 is not "Windows Vista R2" as some have suggested, but it is does have many of the same core elements that Vista has.
5. It's Still Supported. Although Windows 7 has surpassed Windows Vista, Windows XP still has more than twice the market share of both Windows 7 and Windows Vista combined. Those that have applied Windows XP SP3 are still being supported by Microsoft, but Microsoft no longer supports Windows XP SP2, or earlier OS versions such as Windows 2000.
