I’m going to get a computer soon because I have Wndows XP. Can you tell me if Windows 7 is easier than 8? Can I get a computer with a mouse and a keyboard instead of a touchscreen?
Let’s just say that you will probably find Windows 7 more familiar than Windows 8. Though with recent changes to to Windows 8 in the form of Windows 8.1, it’s a bit easier to make the interface more like the Windows you’re used to from using XP. I find Windows 8 to be a fast and stable program.
If you’re willing to take the time to get acquainted with a new system, Windows 8 could work out nicely for you. Another advantage is that support for Windows 8 will last at least three years longer than support for Windows 7. Right now extended support for Windows 7 is scheduled to end in 2020.
Also, depending on your computer, you might not need to buy a new one. You can use the Windows 7 Upgrade Advisor  or the Windows 8 Upgrade Assistant  to determine if your old computer can handle these operating systems.
You can use a keyboard and mouse with either system.
