How to download and install the February 2024 security updates

Microsoft Windows Security Updates February 2024 on Windows 10

Non-managed Windows systems receive security updates automatically by default. This does not happen immediately after release though. Some administrators may prefer to download updates manually to install them on one or multiple devices.

To update using Windows Update, use the following guide:

  1. Select Start, type Windows Update and load the Windows Update item that is displayed.
  2. Select check for updates to run a manual check for updates.

Tip: we recommend to create a full system backup prior to installing any updates on Windows machines. The built-in tools are not overly reliable when things go wrong, and the backup enables you to restore the system in case of critical issues.
