Windows Server 2005, codenamed Monterey is an additional work server built to help people work using workstation apps and Office 2005. It was released on June 23, 2005. You can run an old MacOS system on it. It ended support on July 17, 2016. Its first build was on May 2, 2002. It ran on AMD Athlon 64 X2. People think it would be similar to Windows XP/Windows Longhorn, but nooooooo, it's similar to Vista.
This thing is still under construction to be ready for the full experience of 2005. It’s a little similar to OS X Tiger.
