We just learned about the Operating System.
One type of Operating System is called Microsoft Windows.
This is a program made by a company called Microsoft, that has their headquarters building in Redmond Seattle.
If you have a windows computer, when you turn it on it will start up Windows and let you do things like go to the internet on your web browser, work on spreadsheets, watch videos or listen to music.
The idea of "Windows" is that each of those different programs is in it's own little window space, and you can open or close as many windows as you want.
Windows first came out in 1985 with Windows 1.0.
Every year or two they make changes to Windows to try and make it faster or better, and come out with another Windows with a new name.
Sometimes they call it Windows and then a number that keeps going up, like Windows 1, Windows 2, Windows 3.11.
Other times they name it after the year it comes out, like Windows 95 because it came out in the year 1995.
And then some other times they give it a special name like Windows NT, Windows XP, or Windows Vista.
Whatever the name is, every time they came out with a new Windows they would give it a new name and add some new things it could do.
