System Requirements
If you are currently running Windows Vista, then you can easily install Windows 7. Tests performed by various parties have consistently confirmed that Windows 7 outperformed Windows Vista on a similar hardware configuration. If you are coming from previous versions of Windows (pre-Vista), take note of the following suggested hardware requirements:
• 1 GHz or faster 32-bit or 64-bit processor
• 1 GB RAM (for 32-bit) or 2 GB RAM (for 64-bit)
• 16 GB of available disk space (for 32-bit) or 20 GB of available disk space (for 64 bit)
• DirectX 9 graphics device with Windows Display Driver Model 1.0 or higher (for Aero. Aero is the graphical user interface and default theme in most editions of Windows 7)

Installing Windows 7
It is straightforward—if you’re doing a clean install, simply boot up your computer with the Windows 7 installation DVD inside the DVD drive and instruct your computer to boot from the DVD (you may need to press a key, such as F11 or F12, while the computer is starting to enter the boot selection screen).
While installing you will have a choice between upgrading your existing Windows or installing a fresh copy of Windows. Installing a fresh copy of Windows is recommended.
Windows 7 32 or 64-bit?
When deciding to move up to a 64- bit operating system, you should first consider what 64- bit gets you. Knowing what software runs on 64- bit should influence your decision; you will see no advantage if you are running 32-bit software on a 64- bit OS. You also lose the ability to run 16- bit software
More bits gets you access to more memory; the processor inside your PC communicates with your system memory (RAM) with numeric addressing. Thus, the maximum amount of memory a 32-bit processor can address is 4
gigabytes. Newer 64-bit processors can address 17,179,869,184 gigabytes (16 exabytes) of RAM.

Some of features of windows 7
Taskbar
The taskbar is now more than just a windows-switcher—it is also an application launcher.
Libraries
The Libraries is a new feature in Windows 7. Using the Libraries, you can group your files and folders into logical units so they are easier to manage.
Desktop Gadgets
Gadgets in Windows 7 now have a new lease on life. In Windows Vista, gadgets were constrained to the Sidebar, which was never really a popular feature among people with small-screen computers (netbooks and small portable computers). In Windows 7, gadgets are free to roam about on your desktop
