Is Windows update stuck on checking for updates?

We are going to show you how to reset Windows Update completely using advanced scripts from Microsoft Technet contributors Ryan Nemeth and Manuel F. Gill. These may get things moving if you're stuck or are experiencing one of the following errors:

  • Windows Update error 0x80070424

What is the Windows Update Agent?

It's good for peace of mind to know exactly what you're dealing with before you change it. The Windows Update Agent (WUA) is a program that works in tandem with other update services to push patches to the system. It looks for the version number of your system and then searches a catalog of updates that come from Microsoft. It then downloads any missing files and can install them depending on your preferences.

This tutorial will cover a reset of both the Windows Update Agent and the settings of the Windows Update client. Let's get started:

How to Reset Windows Update Client Settings

TechNet forums user Ryan Nemeth has made resetting the Windows Update client settings much easier by crafting a lightweight PowerShell script.

  1. Download the script

    You can find the first script here (or here). Click “Reset-WindowsUpdate.ps1” to download it and hit “Save”.

  2. Edit the script

    If you aren't using Windows' hidden administrator account, the script may throw up “Access Denied:” errors. You can download our modified script and move to step 4, or right-click the script and choose “Edit”.

  3. Add an administrator permissions prompt to the script

    In Windows PowerShell ISE add the following code at the beginning of the script:

    if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)) {
    Start-Process PowerShell -Verb RunAs "-NoProfile -ExecutionPolicy Bypass -Command `"cd '$pwd'; & '$PSCommandPath';`"";

    Press the save icon. The script should now prompt you to run PowerShell as an admin.

  4. Run the script with PowerShell

    In the Downloads folder or wherever you saved the file, right-click it and choose “Run with PowerShell”.

  5. Accept the Execution Policy Change

    For protection, Windows 10 does not let you run random scripts without its approval. PowerShell may prompt you to change the execution policy. As we only want to accept this script, not all scripts, reply with “Y” in the command line. Press “Enter”.

  6. Wait for the script to run

    The script will now perform all the necessary changes to your Windows Update client. Restart your PC.

  3. Run SetupDiag.exe
