Different Versions of Windows
The version of Windows installed on your new PC is probably Windows XP. Microsoft has released different versions of Windows over the years, and XP is the latestwhich is why it comes preinstalled on most new PCs.
If you've used a previous version of Windowssuch as Windows 95, Windows 98, or Windows Meon another PC, Windows XP probably looks and acts a little differently to you. (It's even different from the version of Windows found in most large corporationsWindows 2000.) Don't worry; everything that was in the old Windows is still in the new Windowsit's probably just in a slightly different place.
There are actually two different retail versions of Windows XP available. Home Edition (which is the version that probably came with your new PC) is the version of XP for home and small-business users. Professional Edition is designed for larger businesses and corporate users. They both share the same basic functionality; XP Professional just has a few more features specially for large corporate networks.
Some new PCs come with a slightly different version of Windows XP called Windows XP Media Center Edition. The Media Center is an optional interface that sits on the top of the normal Windows XP desktop and allows one-button access to key multimedia functions, including My TV, My Music, My Pictures, and My Videos. In fact, PCs equipped with Media Center come with a handheld remote control for quick switching from across the room! If you have Windows XP Media Center, don't panic; underneath the Media Center is the same Windows XP we all know and love, and that is described in this chapter.
