I've had a look at Windows 10 using the Technical Preview release ISO which is free if you 'sign up' with an email address. It looks like a magazine for teenagers and has some aspects that are confusing for me regarding how you arrange the desktop and get shortcuts to work. I'll admit that I tried to make it look like XP so I'm sure I'll be happy to continue using Linux MINT (Mate) which is very easy to make look like XP at the desktop GUI level.
