Here is my summary of radosuaf’s method for installing Windows updates on Windows 7 or 8.1 computers with Kaby Lake or Ryzen CPUs:
Steps that should be done when you wish to manually install updates with Windows Update or standalone Windows update file(s):
(Note: The recent Shadow Brokers code dump has made it clear how important it is to always have the patch for MS17-010 applied.)
Group A:
1. (This step should need to be done only once.) Uninstall all security-only updates (from October 2016 and later) except for the March 2017 security-only update (if it’s installed), and then reboot if asked to. To see a list that includes all of the security-only update knowledge base numbers, see https://www.askwoody.com/forums/topic/2000003-ongoing-list-of-group-b-monthly-updates-for-win7-and-8-1/.
2. If a monthly rollup from April 2017 or later is installed, or a preview monthly rollup from March 2017 or later is installed, uninstall it and reboot if asked to.
3. Repeat step 2 as many times as needed.
4. (This step should need to be done only once.) Install the March 2017 security-only update if it’s not already installed. Reboot if asked to. For links to this update, see https://www.askwoody.com/forums/topic/2000003-ongoing-list-of-group-b-monthly-updates-for-win7-and-8-1/.
5. Install all desired update(s) except monthly rollups or security-only updates. Reboot if asked to.
6. Install the desired monthly rollup. Reboot if asked to.
Group B:
1. Uninstall the security-only updates that have the “lock” and then reboot if asked to. As of June 2017, these security-only updates have the “lock”: April 2017 and June 2017.
2. Install all desired updates except for security-only updates that have the “lock,” and reboot if asked to.
3. Install the security-only update(s) that you uninstalled in step 1, rebooting only after the final update that you installed.
