Windows 10: Windows 10 keeps trying to upgrade my Backup copy of Win7

From time to time I have booted into my Backup copy of Win7 that I cloned before upgrading to Win10.
Every time I do this I notice that after about 15 minutes if I go into Windows Update and check what updates have been installed, I see that it tried a Win10 upgrade and failed.
It doesn't download anything that I can see, it just tries the upgrade.
Why does it keep trying to do this?
I uninstalled KB3035583 and "hid" it. The Get windows 10 icon is gone

:)

 

How do I delay Windows 10 installation?

This does NOT stop the constant attempts (and failures) to upgrade to Windows 10.

I kept a backup copy of Windows 7 before I upgraded and if I boot into that backup copy it keeps trying to upgrade to Windows 10 on that copy even though I have uninstalled KB3035583 and hidden it.

I check the backup copy periodically just in case I decide not to keep Windows 10.

Thanks for the reply Rob.

I think I have the Product Key pasted underneath the cover.

I kinda tried to download a Win7 copy using it from Microsoft download but the site didnot authenticate my product key.

I'll try again tomorrow.

Because even if I find a solution , I have decided to keep a copy of Win7, as a backup.

My system came with Win7 Home . Although it cannot revert on its own ( I checked the recovery under Settings) , atleast I will have something to fall back to if everything fails.

Thanks again for your response.
