how do i stop downloading and installing windows 11

I'll save your response and then let you know what I do. Gosh, I'm old and I hate all of this stuff!

I was just on chat with Microsoft support and he said to just download using this URL.

My PC doesn't have enough space so I am working on that.

I gave him the details of my set up so don't know if this is specific to me, I don't think so.

Let me know how it goes if you try it

I would have to do an upgrade to Windows 21H2. I currently have Edition Windows 10 Home

Version   20H2. Then after that, I could go into the registry and do what you did. I find this to be an awful situation.

I'll let you know what I decide.

I don't think you have to upgrade if you don't want to. In the registry step, when you are imputing a value into TargetReleaseVersionInfo, just put in your current version of Windows that you like (20H2). When Windows Update runs, it should only pull updates for your version of Windows only.

Again, just for reference:

If you decide to update to the latest version of Windows 10 later, all you have to do is change the value of TargetReleaseVersionInfo to the latest version of Windows 10 that has been released according to this help article:

Then, restart your computer. Run Windows Update and you'll be able to update to the version of Windows you put in to the registry.

So what you are saying is that your Laptop does not really support Windows 11. Is that correct?

The rollback to W 10 was fast & everything is back to normal. .My laptop is 6 months old and had never had an issue. This post was interesting but my machine does not support the higher rate. https://winaero.com/enable-dynamic-refresh-rate-in-windows-11-drr/
