HI friends i am using windows XP from 4 years. Now i like to switch my OS environment to VISTA . Will you tell me the minimum hardware requirement for installing VISTA . Waiting eagerly for the reply.

Recomended minimum is 2gb ram for vista, think windows7 is little less, but ive run vista on 512mb wasnt perfect but it worked, check on your motherboard makers website and see if the board needs an upgrade to the bios to run vista, hard drives should be alright but vista operating system will take up 5-6 times as much space.

and if the computer is next to god why cant he fix it, thought he knew everything.

I have Vista at home and Windows XP at work. XP does everything that we need a computer to do, and it is quicker, smoother and consumes less resources than Vista. I finally have Vista running fairly well, but it took quite a bit of doing....including the increasing of my RAM which cost more $.
Why do you want to go to Vista? If you don't have to, don't. You probably will not like it better than XP.

Thanks popeye67 AND busdriver72 for your reply. Actually i know the common work we people do in computer XP is ok for that. But when the question of multimedia or graphics VISTA look far more better to me.

I don't see why you would want to go from xp to vista when you could just get windows 7 which is 10 times better than vista in my opinion.

Windows 7 might have higher system requirements than vista but its worth it. Vista is still full of bugs and that compatibility issue is a pain.

Take a look at this.
