Windows Update has been checking for updates for over 15 hours. I have switched sleep mode and hibernation to never to turn on and the display to remain on too. I am plugged into power from my home and connected to the internet via a cable to my cable internet.
I have not used this computer in 4 years and so expect there are a lot of updates needed/recommended. How long should I give it and at what point should I contact you again if it has not completed the check?
