Update Windows and its drivers

Microsoft issues regular updates to Windows. There are twice-yearly major upgrades, and regular smaller updates, released on Patch Tuesday. It’s important to, at the very least, install patches to keep your PC secure and running as smoothly as possible. In addition, you should make sure you have the latest version of the drivers for your hardware peripherals installed

  1. Press the Start button and choose Settings
  2. Select Update & Security and then Windows Update
  3. Click Check for Updates
  4. If you see a message that says “Updates are available”, choose Install Now
  5. Select the updates you want to install and click Install
  6. Restart your PC

Once it’s restarted, you should notice a difference in performance. But there’s still much more you can do to boost your PC.

Clean up Windows Registry

As you use your PC over the months and years, Windows’ registry database collects lots of files and data. This impacts your PC’s performance. Much of it isn’t needed and you can safely get rid of it. CleanMyPC makes that easy to do.

  1. In CleanMyPC, choose the Registry Maintenance utility in the left hand sidebar
  2. Wait for it to complete its scan of your PC
  3. When it’s done, choose Fix Registry to clean up the database
  4. Press Refresh to scan again
  5. If CleanMyPC tells you that it needs to carry out another repair, click Fix Registry

Use older versions of applications

This one sounds counter-intuitive. Why would using older versions of applications be a good way of reviving a PC? Well, it’s simple really: as applications are upgraded and gain new features, they become bloated and run more slowly. It’s fine if you have a new PC, which has the latest processor and a ton of RAM, it can keep up in the arms race between hardware and software manufacturers. But your old PC probably can’t. If you use an older version of an application that was released around the same time as your PC, however, your PC will run as good as new.

Reinstall Windows

This is a bit of an extreme step, and you’ll have to backup all your data first and make sure you have installers and licence codes for all your applications. But if you do a clean install of Windows, you’ll definitely notice that your PC feels like it’s been completely revived. Also, if you’ve upgraded the version of Windows that runs on your PC from, say Windows 7 or 8 to Windows 10, it’s worth checking the specification of your machine against the recommended requirements for Windows 10. If it’s close to the minimum, consider upgrading your hardware by adding more RAM or more storage space. Swapping your hard disk for an SSD is also a great way to optimize your old PC.

An old PC doesn’t have to be consigned to a cupboard and never used again, there’s plenty you can do to revive it. CleanMyPC is a tool that will help your PC feel fresh and new right after the first clean up. Try it now, you won't regret!
