Why is my laptop so slow?

The usual causes are too many startup apps, low storage, pending updates, or one program using most of the memory or processor.

Restart it, close heavy startup apps, install updates, and check free storage before buying new hardware.

Why laptops slow down

Most slow laptops are not dying — they are overloaded. Programs add themselves to the startup list, the drive fills until the system has no working room, and an old spinning hard drive does the rest. Work through the free fixes in order; they cure the majority of slow laptops.

What to do, step by step

1. Restart properly — a real restart, not closing the lid. It clears programs that have been running (and leaking memory) for weeks.
2. Trim the startup list. On Windows: Task Manager, then the Startup tab. On a Mac: System Settings, General, Login Items. Disable what you do not need at login.
3. Free up drive space — move big videos and old files off, empty the trash, uninstall programs you never open.
4. Install waiting updates for the system and your apps. A stuck or half-finished update is a common cause of sudden slowness.
5. Find the hog: Task Manager or Activity Monitor shows if one app is using most of the processor or memory. Update it, restart it, or remove it.
6. Run a malware scan with your built-in protection (Windows Security on Windows; on a Mac, keep the system updated and scan with a reputable tool).
