How do I disable the Windows 10 update prompt on an existing Windows 10 install?

Question

I've got a number of stick PCs deployed for digital signage that currently run Windows 10.

About a week or so ago, Microsoft released a new update for Windows 10 that I'm getting prompted to install even after closing the prompt repeatedly.

A prompt opens up over the top of Internet Explorer running in kiosk mode, and therefore is interfering with my digital signs.

Is there a way to completely disable this prompt? Installing the update is not an option, because there isn't enough disk space available on the stick PCs to install the update.

Answer 1

There is no other official way to permanently block updates except the Troubleshooter from KB3073930.

But there is a nice 3rd party tool called Windows Update MiniTool which allows to select which updates can be installed and allows to block updates like you could in former Windows versions.

An alternative to the standard Windows Update What you can do: • Check for updates
• Download updates
• Installing Updates
• Deleting installed updates
• Hiding unwanted updates
• Get direct links to the *.cab / *.Exe / *.Psf update files • View update history
• Configure Automatic Updates
• This tool is like the external powershell module PSWindowsUpdate, but much more advanced and user-friendly features
• The tool relies and use same WU infrastructure, all downloading are through WU it's not a downloader

Try this tool to stop offering the update over and over again.

Microsoft released a troubleshooting package that lets you show/hide updates in Windows 10. Looks like they did this because of issues caused by Windows Update installing drivers, but you can use/abuse this for any kind of update it seems.
