How to download and install the August 2024 security update
Security updates are installed automatically on most Windows Home devices. However, this does not happen immediately. Administrators can apply updates as soon as they are released. This is done in the following way:
- Select Start, type Windows Update and load the Windows Update item displayed.
- Select Check for Updates to run a manual check for updates.
Windows Update should display the security update and begin downloading it.
Comment: We recommend that you create a full system backup before you install any Windows updates. This gives you another restore option if things go wrong. The free Paragon Backup is a good option, but there are others.
