logo Windows XP
Microsoft's successor to Windows 2000. The key features are:
  1. You can't easily use a device driver unless Microsoft has oked and digitally signed it. In other words, you can't write your own device drivers any more. You must pay a fee to Microsoft if you want to write one and sell it to others. The advantage of this big brotherism is that Microsoft can ensure device drivers don't crash the OS, making the OS as a whole much more stable than now. XP automatically updates drivers and installs them when new versions are released.
  2. There are copy protections on files. For example the OS can prevent you from copying a program file to CD, or downloading a music file to an MP-3 player. The idea is the OS acts as a copyright cop.
  3. It has support for 64-bit Itanium processors.
  4. It boots much more quickly, or more accurately lets you start working even before the boot process is complete.
It is targeted at both corporate and home users. XP as Big Brother (why you probably want to avoid XP and stay with Windows 2000).

XP-64 is a 64-bit version for the AMD Athlon64, AMD Opteron and Intel Itanium processors. It currently supports up to 16 GB of physical RAM and 16 TB of virtual memory. It has an X86 emulator for 32-bit legacy Windows apps.
