Once your computer system is virus free and has sufficient memory, what is the next upgrade? Should I buy a new computer with the latest Microsoft OS: Windows 10?
NO! What’s wrong with you? Windows 10?
Trust me. Something happened to Microsoft. Stick with your old Windows 7. If you have a Mac, upgrade to macOS Sierra. If you’re running Linux, congratulations. You’re a free thinker, unencumbered by societal norms.
The next upgrade for you is to replace your conventional hard drive with a solid state drive. You may find that your computer will boot twice as fast with an SSD. The fact that a solid state drive has no moving parts makes it less likely that you will lose your important data when your laptop falls off the coffee table. This doesn’t mean you shouldn’t make backups. A solid state drive can still fail. It’s just that in terms of speed, a solid state drive is probably the best way to do things twice as fast for a reasonable upgrade price.
