Fast Windows Updates Install

1 minute read


When you install a fresh copy of Windows 7, it can take a really long time to get it fully patched. Follow this guide to speed things up.

To Resolve:

  1. Download the appropriate (x64 or x86) versions of these three updates: KB3020369, KB3172605, and KB3125574. Follow link in references for download.

  2. Open an elevated PowerShell prompt and run the following commands, which will allow the next updates to install quickly:

a. stop-service wuauserv

b. remove-item c:windowssoftwaredistributionWuRedir

  1. Double-click and run the KB3020369 update (previously downloaded). Should take less than 2 minutes to run, and will not require a reboot.

  2. Now double-click the KB3172605 update you previously downloaded. Follow the prompts. Reboot when it says to. (This step should take about 1 minute).

  3. 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.

  4. Begin WU (Windows Update) after completing the above steps. A list of 60+ available updates should be returned within 5 minutes.

  5. Finish updating normally … rebooting when it says to. You will probably need to reboot and re-check for updates at least two more times.

Done. This usually only takes 2 hours instead of however long it usually takes.

UPDATE: I’m going to add the PSWU script below.

  5. If you haven’t already, run the command Set-ExecutionPolicy Unrestricted.

  6. Open Powershell as admin, Run the command: Import-Module pswu
