have u tried WINDOWS VISTA........................???what are its requirements ?

it wont work in your system as it requires 521mb ram

If you currently have Windows XP on your PC you can go to the Microsoft Windows website, download, install and run their Upgrade Advisor. It will tell you if Windows Vista will run on your PC. The link for this is http://www.microsoft.com/windows/products/windowsvista/default.mspx Microsoft says your PC needs at minimum an 800 MHz processor, 512 MB RAM and a DirectX 9 class graphics card. Your computer will then be "Vista Capable" and capable of running all editions of Windows Vista although some of the special features and high end graphics options may require additional or more advanced hardware. If you have at least a 1.0 GHz processor and an Aero-compatible graphics card with at least 128 MB graphics memory and supporting the new Windows Display Driver Model, your computer will be called a "Vista Premium Ready PC" and will be able to take advantage of Vista's "high-end" features. As a computer professional for many years, I learned a long time ago that being on the leading edge also means being on the bleeding edge sometimes. Who knows if the bugs are all out. I have not heard anything about Vista that makes me want to run out and make the investment right away. My XP works just fine, thank you. In fact, some of the existing software may not work with Vista. I know Quickbooks 2006 doesn't. Personally, I am waiting to see some unbiased reviews on Vista before I rush out and make that investment.

Wikipedia has a fairly good requirements list; http://en.wikipedia.org/wiki/Windows_Vista#Hardware_requirements
