Windows is notorious for slowing down over time. If you’ve never refreshed your PC with a fresh Windows install, now’s the time to do it. Upgrading from a hard drive to an SSD is like speeding up at 30% more. It will make your computer feel much faster, from boot times to application launches to file transfers. This is the single most noticeable PC upgrade you can make. Another way is to add more RAM or by installing an operating system with a lighter footprint than Windows can help you eke more life out of an aging PC.
