Windows Vista Home Basic

Hi,

Here I have listed down the wanted stuff and you own stuff.

Recommended system requirements:

1. 1 GHz 32-bit (x86) or 64-bit (x64) processor - You have 3 GHz
2. 512 MB of system memory - You have same
3. 20 GB hard drive with at least 15 GB of available space - You have 160 GB

Your RAM will be enough for you to perform your tasks on this configuration.

If you are planning to hit that extra mile with games or any other products
that require some "power" better to go for a 1 GB.

Have a nice day!
