Ten Reasons to Upgrade to Windows 7

1. Aero Peak : To quickly peer past all open windows to look straight at the Windows 7 desktop, simply point to the right edge of the taskbar. All open windows will instantly turn transparent, making it possible to see what's on the desktop.
2. Redesigned Taskbar : With Windows 7, getting an application icon onto the taskbar is as simple as right-clicking on the icon and selecting "Pin to Taskbar." Voila, it magically appears on the Taskbar.
3. Aero Snap: With just about every laptop being sold now having a widescreen display, have you ever needed to position two documents side-by-side? Rather than tearing your hair out in frustration, Aero Snap offers a quick and easy way to "snap" windows into the left or right half of your screen simply by dragging Windows to the edges. (You can also snap windows vertically.)
4. Jump List : A Jump List is what you'll see when you right-click on a program icon on the Windows 7 taskbar (or Start menu). What appears depends on the specific application, but typically contains a list of frequently or last-viewed files, as well as quick access to common commands.
5. Improved Boot Performance: 11 seconds from loading Windows to a fully usable laptop without the benefit of Windows 7 optimized drivers is nothing to scoff at
6. Support for SSD: Microsoft has done a lot of re-engineering to Windows 7 since Windows Vista to improve its SSD read and write speeds; the use of ATA commands and support for the TRIM command further increases write speeds.
7. BitLocker To Go: BitLocker To Go (as with BitLocker) is found only on the Enterprise edition of Windows 7. For enterprise users, it allows them to protect the data stored on portable drives by encrypting them on-the-fly. Set up is extremely easy and recovery keys can be managed via policy-configured Active Directory Domain Services integration
8. Enhanced Security: I've been using various editions of Windows 7 for more than half a year now, and its stability is bliss compared with Windows Vista or even Windows XP. While I would be lying to say that it never crashes, it does so infrequently and is otherwise rock stable.
9. Windows XP Mode: Need to run Windows XP due to some legacy OS or to run some potentially dangerous software without any risk to your PC? You can make use of Windows XP Mode to run, well, Windows XP as a virtual machine.
10. Network Virtualization : Ok, this isn't technically something that would qualify as an official feature in Windows 7. However, the folks over at Connectify found that the Windows team did some unfinished work to virtualize the network plumbing in Windows 7. Using it, they managed to build a GUI and an interface that transforms your Windows 7 workstation into a full-fledged AP for other Wi-Fi devices - while it is connected to an AP!
