Quick answer
Turn on automatic Windows updates, leave the built in Windows Security on, and back up photos and documents. You usually do not need to pay for extra antivirus. A strong password and two-factor authentication add another layer.
1. Keep Windows updated
Updates fix security problems and keep the laptop running smoothly. Turn on automatic updates so it happens in the background.
- Open Settings, then Windows Update
- Turn on automatic updates
- Restart when asked, so updates finish installing
2. Use the built in protection
Windows includes Windows Security, which is enough for most people. There is usually no need to buy separate antivirus, which can slow an older laptop down.
- Leave Windows Security turned on
- Be cautious with email links and downloads
- Only install software from trusted sources
3. Back up photos and documents
A backup means your photos and files are safe even if the laptop is lost or stops working. The easiest options are OneDrive, which is built into Windows, or an external drive.
- Turn on OneDrive to back up automatically, or
- Copy photos and documents to an external drive now and then
- Check the backup is working every few months
Add another layer
A strong, unique password and two-factor authentication protect your accounts even if a password is guessed. See our guides on creating a strong password and two-factor authentication.
