How to download and install the February 2025 security updates


Microsoft installs security updates on most unmanaged Windows 10 and 11 devices automatically. This does not happen in real-time, and may take anywhere between minutes after release to days or even weeks depending on use.

System administrators who want to speed up the installation can do so by searching for the updates manually. This is done in the following way.

1. Open the Start menu, type Windows Update, and select the result.
2. Activate the "check for updates" button. This runs a manual check for updates.
3. Activate the "download & install all" button, if the update is not downloaded automatically.

You may also download the updates manually. Use the following links to download the Windows update files directly.
