What are the differences between Windows 95 and Windows 2000?

Well, the huge difference between Windows 95 and Windows 2000 is that since Windows 95 is five years older than Windows 2000 Windows 95 is on the lower end of the scale of revolutionary technology.

Another big thing is the startup sound's origins of the two OSes.

Windows 95s startup sound was made (ironically) by someone on a MAC, while Windows 2000s was made on a cheap piano....

Windows 95 was missing a lot of tools used on Windows 2000, and one huge one was USB support.

See, Windows 95 needs an add-on for it to support USB, while Windows 2000 came with support standard. But then again, did USB even exist in 1995?

Another big fact is that the two OSes are targeted at different parts of life: 95 is targeted for educational and home use while Windows 2000 is a "Professional" (buisiness-targeted) OS. But Microsoft also created a (unstable) home version of 2000 dubbed Millennium Edition. (Millennium Edition is commonly known as ME)
