If you’re running Windows 8 or 8.1, I would suggest taking advantage of Microsoft’s free upgrade to Windows 10. It is a vast improvement over some of Windows 8’s more confusing elements. 10 includes a less confusing Start menu (although I still suggest having me tweak it further to be more like Windows 7!), and much longer support period over previous editions of Windows . On the other hand, if you’re still on Windows 7 and your system is stable, you may want to wait before upgrading to 10. While the majority of systems I have upgraded have gone just fine, there are still some concerns about bugs and stability with 10, as it is very new. To sum up: I generally feel the risks and benefits outweigh the negatives if you’re running Windows 8, but less so if you’re running a stable Windows 7. Want to try Windows 10 on your 7 system to see how it goes? I can do that—I can make a clone of your system and we can see how it plays with your system. If all goes well, then you’re all set. If not, well, then we can revert to the cloned (exact copy) drive and pretend it never happened.
