Missing Windows 7 product #

HP Recommended
HP Pro 3500
Microsoft Windows 10 (64-bit)

I have a HP Pro 3500 C9J26UT Desktop PC Serial [edit]. I upgraded WIndows 7 to Windows 10 and need the original Windows Product Key to activate Windows. I do not see it anywhere on the case and was not given it when I bought the computer from Tiger Direct. PLease email me or call me at [edit]with the product key or where to find it. Thank you.

Welcome to the HP Support Community  @srmarathon 

 

HP and all manufacturers do not retain records of COA's

 

Buy a new W7 Pro 64Bit from eBay.

Hi, @srmarathon 

 

Some HP 3500 Pros came with W8 motherboards, which have the product key in the BIOS.

 

it is possible that your PC has a W8 Pro product key in the BIOS and had downgrade rights to W7 Pro.

 

Run this free utility that I zipped up and attached below, to see if there is a W8 Pro product key in your PC's BIOS.

 

If there is, you may be able to use that key to activate W10 Pro.
