"Even more surprising.. It's almost 2017 and people still run Windows!"
Oh, it's perfectly safe to run Windows (7 in my case) at any time.
As long as it isn't allowed to go online. Ever. That's what I have Linux Mint for.
As for Facebook - I've had 3 accounts over the past 5 years (the last one was nearly 2 years ago) and the longest that any of them lasted was about a month.
