MS Windows XP

Some of the change in Windows XP is the user interface, which includes a revised Start menu and updated Task Bar. The new look is possible because Windows XP can be skinned, which lets the interface be changed dramatically with a new facility called themes. (Memory Support and Windows Operating Systems)
Windows XP shows fast user switching, which allows multiple users to be logged onto their own sessions at the same time on the same machine and, as the name implies, they can switch back and forth quickly. Another new feature, ClearType, is discussed.

Compared to 32-bit systems, which top out at around 3GB of memory, 64-bit PCs offer added responsiveness for people who are running a lot of applications at the same time and switching between them frequently.

The Maximum amount of memory that can be supported on Windows XP Professional and Windows Server 2003 is 4 GB. It is split into 2GB and 2GB for different areas. The address space is usually split so that 2 GB of address space is directly accessible to the application and the other 2 GB is only accessible to the Windows executive software. It was released on October 25th 2001. The cost is about $90 and up.
