I have a Windows 8.1 Pro workstation that I do all my work on. The company I work with says they will not support Windows 10.

As far as I remember, I never asked to have this machine to upgrade to 10, but I noticed in the Action Center - Reliability history that starting on Aug 2 it has a warning that it Failed to Upgrade to Windows 10 Pro everyday.

Installation Failure: Windows failed to install the following update with error 0x80240020: Upgrade to Windows 10 Pro.

How do I make it stop trying to update? I did upgrade a laptop. Is it tied to my MS User Account some how?
