  1. 1. Restart properly
  2. 2. Cut down startup programs
  3. 3. Free up disk space
  4. 4. Check what's using the CPU and memory
  5. 5. Pause OneDrive / cloud sync while you work
  6. 6. Scan for malware
  7. 7. Consider an SSD or more RAM

A slow laptop is usually starved of memory, clogged with startup programs, or running out of disk space — rarely a hardware fault. Work down this list and you'll feel the difference.

1. Restart properly

If you only ever close the lid, your laptop never truly resets. A full Restart clears memory and stops runaway background tasks.

2. Cut down startup programs

Open Task Manager (Ctrl + Shift + Esc), go to the Startup apps tab, and disable anything you don't need launching at boot — chat apps, updaters and "helper" tools are the usual suspects.

3. Free up disk space

Windows slows badly when the drive is nearly full. Go to Settings > System > Storage, turn on Storage Sense, and clear temporary files. Aim for at least 15% of the drive free.

4. Check what's using the CPU and memory

In Task Manager's Processes tab, sort by CPU and by Memory. If one program is constantly pegged at the top, that's your bottleneck — update or reinstall it.

5. Pause OneDrive / cloud sync while you work

Heavy cloud syncing can hammer an older laptop. Pause it temporarily to see if responsiveness jumps.

6. Scan for malware

Hidden malware is a classic cause of constant slowness. Run a Quick scan in Windows Security.

7. Consider an SSD or more RAM

If your laptop still uses a mechanical hard drive, moving to an SSD is the single biggest speed upgrade you can make — often turning a 3-minute boot into 15 seconds. Adding RAM helps if you keep many tabs and apps open. We can tell you exactly which upgrade fits your model.

Frequently asked questions

Why is my laptop so slow all of a sudden?

The most common sudden causes are a nearly-full disk, a Windows update running in the background, too many startup programs, or malware. Restart, free up space and check Task Manager first.

Is it worth upgrading an old laptop?

Often yes — adding an SSD and more RAM can make a 5–6 year old laptop feel new for a fraction of the cost of replacing it. We're happy to check whether yours can be upgraded.
