Upgrading to Windows 7 is not for Everybody
Recenly Microsoft announced that they will be ending support for Windows XP in August of 2014. This means that they will no longer be providing system updates for the operating system. Therefore, they recommend that all users upgrade to Windows 7, the most current version of the Windows operating system.
Before making the move to upgrade, existing users need to examine their current hardware. For those who have PC's that are older than 5 years, it may be better for them to buy new computers with Windows 7 on them. After four years, PC's tend to become less reliable and more unstable.
Users who are still running Windows Vista and are not experiencing freezes or blue screens should strongly consider upgrading their memory to at least 2 gigabytes. If Vista is not giving you any problems, there's little reason to upgrade to Windows 7, since Windows 7 is simply Windows Vista that works.
