Win 10 fixed my old laptop up a lot when upgrading from 7, if you have an older computer which originally had Win 7, upgrading to Win 10 may deliver a much needed performance boost, depending on age. Also fixes some issues your computer had in Win 7 on the upgrade to 10. My computer's hard drive couldn't take being half full on 7 until now. And I hope we all agree that Win 7 was a security hassle...Widgets were a danger. And now due to Win 7's old age, security is even more of a danger as the code is more easily crackable.
