Quick Fix
01 If it still has a mechanical hard drive, cloning it to a cheap SSD is the single biggest speed-up an old computer can get — often the difference between "unbearable" and "perfectly fine."
02 Pair it with more RAM (to 8–16 GB) and a clean-up of startup apps.

Most “old and slow” computers aren’t worn out — they’re held back by a slow disk, too little memory, and years of clutter. A little effort and a small spend can make one genuinely pleasant to use again.

1. Add an SSD (the big one)

If the machine still boots from a spinning hard drive, this is transformative. An SSD makes boot, app-launch and everyday use feel like a new computer. You can clone the existing drive to the SSD (keeping everything) or do a clean install. On a laptop it’s often a single access panel; on a desktop it’s trivial.

2. Add RAM

4 GB struggles with a modern browser and OS. Going to 8 GB (or 16 if the machine takes it) stops the constant disk-swapping that makes things stutter. Check what your model supports before buying.

3. Clean up the software

  • Trim startup apps (see why your laptop is slow).
  • Uninstall software you don’t use, especially old “utility” and toolbar junk.
  • Free up disk space to keep the drive under ~90% full.

4. If Windows itself is the limit

A 2015-era machine may be stuck on Windows 10, which lost security support in October 2025. Two honest options:

  • A lightweight Linux distribution (such as a beginner-friendly one) runs well on old hardware, still gets security updates, and handles web, email and documents comfortably. It’s the best way to keep an otherwise-dead machine safe and useful.
  • ChromeOS Flex turns an old laptop into a Chromebook-style device for web-first use.

Both are free and sidestep the “no supported Windows” wall. Check your machine’s status in the support tracker to see whether this applies.

When it’s genuinely not worth it

If the machine can’t take an SSD or more RAM, or a repair is needed on top, price the total against a good used business laptop with support life left. Sometimes the kindest upgrade is a different (used) machine.

Frequently asked questions

Will an SSD really make that much difference?

On a machine still using a hard drive, yes — it’s the most noticeable upgrade you can make, more than a faster processor would be.

Is Linux hard to switch to?

Less than it used to be. For web, email, video and documents, a friendly distribution is straightforward. Try it from a USB stick first without installing.

Can I upgrade a MacBook?

Older Intel MacBooks often allow SSD/RAM upgrades; recent Apple-silicon models have everything soldered and can’t be upgraded — there, longevity comes from the long macOS support instead.
