Microsoft Windows 7 is the next operating system of Microsoft which aims to replace the much criticized Windows Vista. Windows 7 seems to have good vibes among early adopters saying it has the features of Windows Vista and the speed of Windows XP. This operating system has major improvements in the areas of performance, driver support, security, navigation. The security of Windows 7 has dramatically improved as the User Access Control which made life difficult for users in Windows Vista now comes with a slider control. This give users the level of security and prompts they want to be shown in the system. As Microsoft describes: “The taskbar at the bottom of your screen is what you use to switch between the applications you’ve got open. In Windows 7 you can set the order in which the icons appear and they’ll stay put. They’re easier to see, too. Click once on the new large icons or bigger preview thumbnails and you’re ready to go. You can even see a full screen preview before switching to the window.”
