THE SYSTEM REQUIREMENTS FOR WINDOWS XP, VISTA, 7 & 8.

To be used efficiently, all computer software needs certain hardware components or other software resources to be present on a computer. These prerequisites are known as (computer) system requirements and are often used as a guideline as opposed to an absolute rule. Most software defines two sets of system requirements: minimum and recommended. With increasing demand for higher processing power and resources in newer versions of software, system requirements tend to increase over time.

In summary, System Requirements with regard to the operating system (Windows XP, Vista, 7 & 8) are those features that will be needed in your computer system to enable it run the above mentioned versions of the windows operating system.

Some people always love to upgrade from Windows XP to Windows 7 while others will love to upgrade from window 7 to window 8 but without confirming whether their computer has the features that will be needed for the upgrade.

If your computer system does not meet the requirement of any version of the windows operating system mentioned above, and you insisted in upgrading the operating system, either you encounter an error along the line or the operating system will not function effectively after the upgrade.
