You really don’t have to reinstall Windows to fix slowness — this trick works wonders

When Windows slows down, reinstalling it often seems like the safest option. It promises a fresh start, with your system running the way it did on day one. More often than not, performance problems begin with cluttered storage rather than a failing operating system. Every day, activity builds up huge photo libraries, project folders, sync services, and app data. When all of that lives on the same drive as Windows, it puts an extra load on that drive.
