Don't worry your computer won't suddenly stop working on January 14th. It will just start to become less secure and receive less support over-time, not just by Microsoft, but by other vendors as well.
We can help though - as most Windows 7 capable machines are perfectly capable of running Windows 10.. so it's worth bringing it in for a check. Most upgrades include keeping your data exactly where it is, and some Computer Buddies tweaks will make using the operating system a breeze *and feel very familiar.
So before you go out and buy a new computer, save some money and have us check it over first for our professional opinion.
