Many older (or cheaper) Windows laptops come with traditional mechanical hard drives—which these days, are pretty outdated and slow. Upgrading to a new, super fast solid state drive (or SSD) is the surest way to speed up an old computer. There’s one problem: moving your Windows installation can be tricky, especially since SSDs are often smaller than their traditional hard drive counterparts.
However, there is a way to migrate your Windows 7, 8, or 10 installation to an SSD without reinstalling Windows. It takes a few extra steps, but a lot less time.
