Intro

If your computer has been slowing down or showing its age, you might not need to replace it just yet. Wirecutter senior staff writer Kimber Streams, who covers laptops and accessories, shares practical steps for reviving an old machine—and how to tell when it’s finally time for an upgrade.

Kimber explains what causes computers to slow down over time, the simplest DIY fixes that can make a big difference, and what to look for if you do end up needing to shop for a replacement. See more of Kimber’s tips in this article on reviving an old computer. 

This episode covers:

• Cleaning up storage and files: Freeing up storage is one of the simplest ways to make a computer feel faster. Check what’s taking up space and remove any and all unnecessary files.
• Tidying apps and removing unused apps: Kimber recommends uninstalling unused apps that come pre-installed on your laptop, plus any unused browser extensions, that may be slowing down your system.
• Why you should update your computer’s operating system: Kimber emphasizes the importance of software updates for both security and performance.
• When it’s time to consider buying a new computer: If you’ve completed all of the housekeeping steps and find that your computer still isn’t functioning the way it should, it’s time to look at your budget and what you need in a new computer.
• Guidance for buying refurbished and secondhand computers: Kimber recommends only buying from manufacturer refurbished programs, and to be wary of retailer refurbs if you can’t see the item in person and judge the condition yourself. Look for a refurbished computer with the longest warranty possible.
