A slow PC can turn even simple tasks into a frustrating experience. Apps take longer to open, Windows feels sluggish, and everything seems to take longer than usual. My first instinct used to be to blame aging hardware, but I’ve learned that it’s worth investigating before spending money on an upgrade. Windows has plenty of ways to hide what’s going wrong, and the built-in tools don’t always tell the whole story. That’s why I keep a few free utilities around to dig deeper, understand what’s happening behind the scenes, and figure out what deserves my attention.
