These days, most new PCs ship with an internal solid-state drive installed. If you're still using a traditional spinning hard disk, you're missing out. Swapping in an SSD is one of the best upgrades you can make to speed up your computer. It'll boot faster, programs will launch instantly, and games will load quickly. You could always reinstall Windows from scratch—in many cases that may even be preferable. However, if you have the right tools, you can get your Windows machine up and running much sooner by copying the entire drive over to your new SSD.
