1.A quick & better desktop : Windows 7 gets you around your PC faster than ever before. 2.After setting up your HomeGroup on your first Windows 7 PC, any new Windows 7 machine that’s connected to the home network will be automatically detected. This means a new Windows 7 laptop can instantly share the printer connected to the desktop PC in the study, for example. It also allows any PC on the HomeGroup to share documents, photos, music, video and other files across the network. Files on other Windows 7 PCs can be searched for as if they were stored locally, using the new Libraries function in Windows Explorer. 3.Windows 7 has key performance improvements to take up less memory and run background services only when you need them. 4.The Start button search facility introduced with Windows Vista has been given a spruce up that makes it a genuine timesaver. 5.Your antivirus software is out of date! Wireless networks detected! Windows 7’s System Tray spewed out pop-up warnings for you 6.Windows Media Player now includes the option to play back music on other networked devices in the home, not only the PC you’re sat in front of. So, for example, you could be sitting in the lounge with a laptop and select a music track to play back through a media-streaming device with its own dedicated speakers, instead of your tinny laptop affairs. 7.Windows Touch : Use your fingers to browse the web, flip through photos, and open files and folders on a touch screen PC–for the first time, Windows includes true multitouch technology. 8.Device Stage has the potential to become incredibly useful… or Windows 7’s UAC. This feature sees Microsoft create specific “homepages” for devices such as digital cameras, smart phones and printers, and hand them over to the device manufacturer. 9.It’s one of those features that’s so obvious you wonder how it took Microsoft so long to cotton on, especially since it’s been a feature of Linux distributions for years, but new Wi-Fi networks are now only a click away. 10.A quick peek in the revamped System Tray reveals a new Bluetooth icon. Windows 7 adds support for Bluetooth 2.1, making it easier to discover and pair devices using a simple wizard.
