Oddly enough, my system doesn't have a COA label! Not on the top, left, right, or rear. On the left side it does have the HP support sticker and another sticker with the HP model and serial numbers.
I'm not sure about my Father's machine, I'll have to take a look next time I am at his home.
Sometime in November I will be re-installing Windows 10 on my Father's machine just so that it has a clean, fresh installation without any remnants of Windows 8.1 being leftover. I am just waiting to do this until his current temporary work is complete.
I noticed that my system is much less cluttered since I opted to "delete everything" when doing the upgrade from 8.1 to 10. seems to be the better route to go, but that's just me......very anal about this sort of thing. Therefore I volunteered to complete the task on his machine as well.
