This is gonna be a quick post. I recently updated my old Windows 7 laptop to Windows 10. I had debated this for a while and it was definitely worth it. If you have the chance to update to Windows 10 for free, I would suggest doing it!
What does it do?
First of all, boot up is way faster. Like less than a minute (when my old laptop used to take 3 minutes). There are a lot of other bells and whistles too like built in security and Cortana (Windows version of Siri). Microsoft Edge, the new internet explorer and is pretty slick too.
If you update, check that all your programs will work with Windows 10! That's it for now!
