I will provide you certain features of windows7 so that you could be able to differentiate between them.
1. Don't need a new PC
Windows 7 will become the first major Windows release that any of us can remember that doesn't require better hardware than its predecessor. In fact, it might even run on systems that struggle with Vista, especially netbooks.
Our real-world benchmarks show that the performance difference between Vista and Windows 7 is zilch. Our Office benchmarks and video-encoding tests completed in precisely the same time, regardless of which OS was installed on our test machine. However, there's no doubt that Windows 7 feels faster. Applications open in a snap, and there are fewer instances of the whirly waiting wheel that afflicts Vista.
Better still, it runs happily on netbooks. Although we've seen a few netbooks such as the HP Mini-Note 2133 pre-installed with Vista Basic, most resort to Windows XP. However, we installed Windows 7 on an MSI Wind, with an Intel Atom 1.6GHz processor and 1GB of RAM, and it performed spotlessly.
The Aero interface is smooth, menus responsive, even Media Center works with commendable polish. What's more, it goes from power off to booted and ready to use in around 50 seconds - only ten seconds slower than Windows 7 boots on a Dell M1330 laptop, with a Core 2 Duo T9500 running at 2.6GHz and 3GB of RAM.
2. Big-screen support
Large, high-definition displays are much better catered for in Windows 7. First, there's no more fiddling around in the Control Panel to make your desktop appear on an external display - pressing Windows + P brings up a pop-up menu with options to duplicate, extend or transfer your desktop on to the second screen.
There's also good news for those who've been squinting at the mammoth LCD panels connected to their PCs. The telemetry from Microsoft's Customer Experience Programme revealed that only half of Windows users are running their PCs at native resolution, with others artificially reducing the resolution as they're struggling to read the text.
Consequently, there's a new option to boost the text and other onscreen items to 150% of their normal size. We tested this feature on a 30in widescreen display and it instantly made the text more readable, although you obviously have to sacrifice some screen real estate - which is the main reason for choosing a bigger screen in the first place.
The art is finding a reasonable compromise. If you simply want to zoom in on a small portion of the screen, the Mac-like magnifier allows you to smoothly zoom in and scroll around the screen.
3. Start button search
The Start button search facility introduced with Windows Vista has been given a spruce up that makes it a genuine timesaver. Instead of merely hunting for exact filename and application matches, the search is more intelligent.
Search for "disk" for example, and not only do applications such as Disk Cleanup and Disk Defragmenter appear as they would in Vista, but also Control Panel tasks such as "Create and format hard disk partitions" and "Create a password reset disk".
It isn't a straight keyword search, either - "Use tools to improve performance" comes up when you search for "processor", for instance. It's a clever way of making hard-to-find Control Panel features more accessible.
11. Revamped Taskbar and jumplists
Replacing the Taskbar window tabs with large, chunky icons isn't big, clever, nor particularly innovative - Apple's Mac OS X Dock and the KDE interface have been doing this for donkey's years.
Sometimes, however, ‘borrowing' ideas from others is better than attempting to reinvent the wheel, and our hands-on tests with the new Windows 7 interface at the Professional Developers Conference (the user interface isn't incorporated into the Windows 7 build Microsoft has released for testing) showed that Microsoft was right to flatter its rivals with a little imitation.
Not only are the bigger icons more finger-friendly for those running Windows 7 on a touchscreen PC, they also conceal the new "jumplists".
Accessible through a right-click (or an upwards swipe of the finger) on the Taskbar icon, the jumplists spring out to reveal a bevy of handy shortcuts that are tailored to that particular application. These might be recently opened documents in Word, music player controls in Windows Media Player, or a link to open the privacy mode in Internet Explorer, for example.
Jumplists are also available from programs listed in the Start menu, with a pop-up box appearing to the right. And, at long last, Microsoft has finally made it possible to drag and drop the Taskbar icons into the order you wish, without having to download the TweakUI PowerToy.
12. HomeGroup
With the average household now containing multiple PCs according to Microsoft, home networking is heading towards the mainstream. HomeGroup should help make it easier. After setting up your HomeGroup on your first Wind
