How to download and install the January 2017 security updates

Microsoft releases individual patches for Windows Vista, and cumulative updates for Windows 7, Windows 8.1 and Windows 10.

This means that options are limited when it comes to updating systems running Windows 7 or newer versions of Windows.

Patches are provided via Windows Update. Please note that the full security and non-security rollup updates are provided through Windows Update, but not the security-only rollup updates. If you only want security updates, you have to download them from the Microsoft Update Catalog instead.

Download links are provided in the next section below.

To check for updates on Windows Update, do the following:

  1. Tap on the Windows-key on the keyboard, type Windows Update, and select the result of the same name.
  2. Click on the check for updates link on the page that opens if that is not done automatically.

Updates are also made available on Microsoft’s Download Center and through the Microsoft Update Catalog. Microsoft stopped releasing monthly security releases in August 2016 apparently.
