# Uninstall Windows Updates

## PowerShell Script

The following is the **Uninstall Windows Update** **KB** **5000802** sample PowerShell script. Copy it and save it as a **.ps1** file or download it from here [http://faronics.org/proservices/UninstallWU.ps1.](http://faronics.org/proservices/UninstallWU.ps1)

```
wusa /uninstall /kb:5000802 /quiet /forcerestart
```

{% hint style="danger" %}
Note that this example is **specific** to **KB 5000802**; you will need to **replace** the Patch **KB Number** with the **Patch KB Number** of the **Windows Update** that you wish to **uninstall**.
{% endhint %}

1\. Edit the script to replace the Patch **KB Number** (5000802 in the example above) with the **Patch KB Number** to be uninstalled.

2\. **Optional:** Remove **/forcerestart** from the script to prevent an instant restart.

{% hint style="info" %}
It's recommended that the **/forcerestart** remains in the script but it is not mandatory.
{% endhint %}

3\. Save the script as a **.ps1** file.

4\. Self-host the script - see [Quick Guide to Self-Hosting Custom Scripts](https://docs.faronics.com/faronicsdeploy/custom-scripts-powershell-vb-batch/custom-scripts-library/quick-guide-to-self-hosting-custom-scripts).
