Hello and welcome nautique is this a build or bought machine?
Whatever it is it should have a sticker with the edition code on it.
If it hasn't I would be rather suspicious.
If you want to find what is on the machine run this Speccy - Download
< from piriform it will give al the viatl stats on the machine and software etc
See my pic to see what it will show you when you click on operating system its; also a good app to have on board for times of queries, and it is free.
