OK! so you are planning to upgrade your Windows operating system to the latest Windows 7. You will have bunch of tools and utilities running in that Windows XP or Vista operating Cpu (I am concerned about the paid software’s you have). Sometimes you will have additional hardware attached to it as an enhancement (Something like an additional Sound card or Graphics Card) Alright everything works great in your Old operating system. But how about Windows 7? How do you know if your existing hardware and software is compatible with it?

So it is important that you should know the compatibility beforehand to avoid a catastrophic situation. So how do understand and know that it all the existing hardware/software will work on your windows 7? Windows has an upgrade advisor tool and that will scan and tell you the compatibility. But I have something better than that and it’s called Windows 7 Compatibility Center. Compatibility center is a database of complete Hardware and Software and when you enter information about a particular product name or model it will search and show you if it is compatible with the Windows 7 operating system. (It will display the compatibility for both 32 and 64 bit operating systems.

If you are going to buy hardware such as a printer, graphics card, camera, media players etc this site is very useful to know the Windows 7 Compatibility in advance.

Hope you will find it helpful!
