If you have decided to get turn to windows7 then you need to take some basic steps. But before installing Windows7 first go through the Windows7 advisor. It will let you know about the specific requirement which your system should have. Hence make sure whether your desktop or laptop PC is capable of running Windows 7. If it's already running Vista with acceptable performance, then the answer is yes. 1 GHz or faster 32-bit (x86) or 64-bit (x64) processor; 16 GB available disk space (32-bit) / 20 GB (64-bit); for the download version, an additional 3 GB is required; 1 GB RAM (32-bit) / 2 GB RAM (64-bit) graphic card of DirectX 9 graphics processor with WDDM 1.0 or later driver. So go ahead and try that kind of thing if you want, just don't use your license key on that type of machine. It may run, but you'll spend a lot of time waiting for it, and it won't display the glassy new aero interface and enhancements.
Before Installing Windows7 judge your requirement and system configuration. There are different editions of Windows 7. So decide which one you need. Home Premium, Professional, and Ultimate. For most people, Home Premium will make the most sense. If your company decides to upgrade, Professional supports domain joining, network backup, and XP emulation. Ultimate includes everything in both other versions, and adds Bit Locker encryption.
The key thing to consider here is that you have to do a custom installationwithout the ability to carry your apps along. You can move from particular Vista to corresponding Windows7 only, say from Vista Home Premium to Windows 7 Professional. The exception is Windows 7 Ultimate, which will let you perform an in-place upgrade from any level of Vistaas long as you don't change whether you're using the 32- or 64-bit version.
Also compare the prices and special offer because lots of manufacturing companies are providing some good upgrade option for free, such as those for students and family packs. And if you're installing on a machine you've freshly built, you can pay less for OEM versions that don't include all the packaging and support. The Student upgrade license is just $29.99, and PC part suppliers offer the OEM versions at steep discounts as well.
Select from 64-bit or 32-bit operating system. Any computer manufactured in the last few years will probably have a 64-bit capable CPU. The rule of thumb is that if you have, or intend to install, more than 3GB of memory on your PC, you want 64-bit Windows.
And don't worry about your old 32-bit programscompatibility features inside Windows allow most of these to run in the 64-bit OS, the exceptions generally being antivirus software and hardware drivers. One significant holdback, however, is Adobe's Flash. If you run the 64-bit version of Internet Explorer that comes with Windows 7, you won't be able to view Web sites that use Flash. But there's an easy fix: Run 32-bit IE for those sites until Adobe gets with the program.
Both 32- and 64-bit installation discs come in the Windows 7 box, so you only have to specify which you want if you're downloading the code. In short, my recommendation is that if your system can run 64-bit software, go for it: You'll be using your CPU and memory more efficiently, and you'll be future-proofed for upcoming 64-bit.
Before installing windows7, one most important thing is that don't forget to backup your data, Suppose if you have some special feature in email client and browser you can import those feature to the latest version of Windows7 system.
