A Preview update installed without my initiating it

I never install 'preview' type updates so I was surprised this morning when a message showed that my computer needed to restart to finish installing a preview update, KB5005539, for .NET Framework. I had no choice at this stage but to allow it to complete the install but I am baffled as to how it happened. I thought preview type updates did not install automatically and had to be initiated by the user but I did not open the Settings\Update & Security then click on 'Check for updates'.

Has anyone else had a preview update 'pushed' on their computers without permission?

Thanks.

Thanks guys.

Using Local Group Policy editor I changed "Manage Preview Builds' to 'disabled' and also changed Windows Update to "Notify for download and auto install".

Hopefully it won't happen again but I will report back if it does.

Personally I paused the Windows Update on my computer to prevent automatically downloading and installing preview updates

wiganken, next time you can click or tap on Pause Windows Update for 7 days to prevent automatically downloading and install preview updates

Yep, there is no reason to install update previews.

Start using Windows Automatic Update Manager

Option 7

Why did i not know about option 7 till i read this?!? Now my preferred method. no pause or anything needed. does it when i want it to.

If you look at my photo in post #1 you will see another 'Preview' type update KB5005611 waiting for me to install should I wish to but this is 'Optional' and did not get 'pushed' onto my computer. So there were two updates, both 'Preview' types, but one gets 'pushed' and the other doesn't. I thought all 'preview' updates were optional and should never get pushed. Weird.

Watch this space.
