How to download and install the May 2018 security updates

Note: it is recommended that you create a backup of the system before you install updates.

All security updates and cumulative updates for Windows are released through Windows Update and other update services that Microsoft operates or makes available to customers.

While all client versions of Windows are configured to download updates automatically, you may speed up the process with a manual check.

  1. Tap on the Windows-key to open the Start Menu.
  2. Type Windows Updates and select the result.
  3. Click on the "check for updates" button if the update check is not run automatically.

Windows checks for available updates and will download any it finds. Note that this will include new feature upgrades for Windows 10. If you don't want those, download the cumulative updates for your operating system manually or configure Windows 10 to postpone feature upgrades.
