Windows Update

A trick we have learned:
  1. Download the appropriate (x64 or x86) versions of these three updates: KB3020369KB3172605, and KB3125574.
  2. Open an elevated PowerShell prompt and run the following commands, which will allow the next updates to install quickly:
    1. stop-service wuauserv
    2. remove-item c:\windows\softwaredistribution\WuRedir
  3. Double-click and run the KB3020369 update (previously downloaded). Should take less than 2 minutes to run, and will not require a reboot.
  4. Now double-click the KB3172605 update you previously downloaded. Follow the prompts. Reboot when it says to. (This step should take about 1 minute).
  5. Double-click and run the KB3125574 update (previously downloaded). Should take about 12 minutes to run. It will require a reboot that takes 5 minutes to complete.
  6. Begin WU (Windows Update) after completing the above steps. A list of 60+ available updates should be returned within 5 minutes.
  7. Finish updating normally … rebooting when it says to. You will probably need to reboot and re-check for updates at least two more times.
