HP Recommended
Product: HP Z440 Base Model Workstation
Operating System: Microsoft Windows 7 (64-bit)

Hi All,

 

I used the recovery tool in the computer's BIOS to perform a factory reset on my Z440 running Windows 7. The computer will not start now and asks me to use a boot disk to continue. I have created a Windows 11 boot disk as I may as well try to update the operating system. The problem is I don't know my windows 7 serial number and there is no sticker on the box listing it. Is there any way to find this number out?

 

Thanks,

Lee
