Message regularly comes up saying windows is not genuine even though it is and it came with the laptop. The desktop background us not black however, updates don't install and when Microsoft's scan is run it finds that windows is not genuine.
Uninstalling KB3004394 or any other update wouldn't fix this.
Assuming Win7 64-bit with Internet Explorer 11 (IE11) installed...
Please answer each of the following [admittedly tedious] diagnostic questions in a correspondingly-numbered list in your very next reply, preferably
without quoting my post:

or did you upgrade the computer to Win7?

- What is the full name of your installed anti-virus application or security suite and
when (approx. date) does your current subscription expire? What anti-spyware applications (other than Defender) are installed? What third-party firewall (if any)?
- Has a(nother) Norton application or a McAfee application EVER been installed on the computer
since you bought it?
- Did a Norton free-trial or a McAfee free-trial [PICK ONE] come preinstalled on the computer
when you bought it? (Doesn't matter if you never used or Activated it.)
