     A laptop with 4 GB of RAM can still be useful, but modern Windows and web browsers use a lot of memory. The steps below start with free fixes and end with upgrades that make the biggest difference.

Quick answer

    Disable startup apps, limit browser tabs, free disk space, and if the laptop still has a hard drive, replace it with an SSD. That upgrade usually makes the biggest difference.

Free fixes

1. Disable startup apps

Open Task Manager → Startup apps and disable what you don’t need. Fewer background programs means more free memory.

2. Control your browser

  • Keep only a few tabs open.
  • Remove browser extensions you don’t use.
  • Use your browser’s built-in sleeping tabs or memory saver option if it has one.

3. Uninstall programs you don’t use

Go to Settings → Apps → Installed apps and remove old software, trial programs and toolbars.

4. Free up disk space

    Keep at least 15% of the drive free. Use Storage Sense and delete temporary files as described in our guide on freeing space on the C: drive.

5. Reduce visual effects

    Turn off Transparency effects in Settings → Personalization → Colors, and choose Adjust for best performance in System Properties → Advanced → Performance Settings.

6. Scan for unwanted software

Run a full scan with Windows Security. Unwanted programs and adware can use a lot of resources.

Upgrades that make a real difference

7. Replace the hard drive with an SSD

    If your laptop has a traditional hard drive, an SSD makes startup, app launching and everyday use much faster. It’s usually the best upgrade for an older laptop. Back up your files first, and check your model’s guide for compatible drives.

8. Add more RAM if possible

    Some laptops let you upgrade to 8 GB, while others have RAM soldered to the board. Look up your exact model before buying anything.

9. Start fresh

    If the laptop has years of clutter, back up your files and use Reset this PC → Remove everything for a clean Windows installation.

A note on Windows versions

    Windows 10 reached end of support in October 2025, so make sure your laptop gets security updates. If it’s eligible for Windows 11, 4 GB is the minimum, so it works best with an SSD and light use. If the hardware is too old, consider a lightweight alternative operating system.
