Hello my name is Nic, I apologize in advance if my problem is being repeated...


I have a friend with a refurbished HP Probook 6570b, of course no sticker containing S/N or any neccessary information. It's does have the Win7 sticker and upon reviewing specs Win7 was recommended OS. Anyway someone upgraded OS to Win 8.1, which has caused performance issues now. To my surprise though the Laptop is working better than I expected. On top of that I am unable to restore to factory settings. I believe that the hidden recovery partition was over written or wiped.  Of course to ISO file on hand or recovery discs either. Don't even have the product key for original Win7 OS.


So my questions are as followed:


1) Am I able to use recovery software to retrieve any useful information?


2) Would I be able to use Command Prompt to find S/N#


3) How would I find the factory ISO file? If found, how do I recover authentic product activation key?


I would be greatful for any help or steps I can take to fix this problem. Thank you and sorry in advance!!!

Hi cannon.services :)

You could try using ProduKey by NirSoft, to see if you can recover the product key embedded in the BIOS for that laptop. It might not work, but it's worth a try.


I don't think that the Serial Number will be of any use to find the original product key, unless you call HP. But even there, I think they'll ask for a proof of purchase (original one), which your friend probably doesn't have. Here's other methods you can use to find the product key:


Factory .iso are usually not available for download on the manufacturer's website, you have to call them and ask for a set of recovery discs, which will most likely cost you money. If the key is still embedded in the BIOS though, you should be able to install Windows 7 from a normal, clean .iso and the activation should be automatic. There's no guarantee from my part however as that whole activation process can often work in mysterious ways. I can do some research on it however if needed.
