Windows 7 is the best. It runs all of the old software from Windows 95 and Windows XP. Well so does Windows 8 but there is a couple of things not working on 8. Windows 7 also has a start menu and is much faster than Windows 8. In short Windows 7 is better than Windows and and I don't know why they started Windows 8 as we don't really need it. Okay I can understand them saying that Windows XP is an older OS. But why should we upgrade to Windows 8 when there are some flaws in it and it does not run all of the software that Windows 7 does?
