if you have a laptop or computer running windows 7.. guess what.. that means you get a windows 10 upgrade for free!! thats right.. this is still valid to this day.. it just simply isnt in the "auto update" any longer for windows 7, 8, 8.1 ..
simply go here
https://www.microsoft.com/en-us/softwar ... /windows10
and follow the instructions to install windows 10 on your machine
btw im not responsible for any problems that arise from a failed installation, so do this at your own risk, this is a decsision YOU have to make.. you also need allot of data to do this (at least 5gb recommended)
you can update to windows 10 right from within windows 7, 8, 8.1 itself if you follow that link and click "update now"
