Recovering OEM license information from HP notebook serial number

All we need is an easy explanation of the problem, so here it is.

I have an HP notebook with a valid Windows OEM license. This notebook has been left unused for sometime and it’s now without an operating system since I installed a brand new hard drive on it. The previous hard drive is no longer available.

Unfortunately I was quite shocked to notice that Windows sticker on it has faded and I no longer can see the Windows OEM serial key (or wherever it calls that long activation string).

I’ve tried to use the HP website to get in touch with HP but it says my warranty has expired and doesn’t allow me to send an e-mail or talk with a customer support representative.

Does anyone know if there is any way to recover this information?

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

As explained in our Windows 7 Activation FAQ, OEM licenses are usually preactivated using System Locked Preactivation (SLP). If you use any HP OEM Windows 7 installation disk, it should activate automatically for you. Because of how the SLP process works, you don’t need to know your key, because the activation occurs automatically if your machine is verified to be an HP.

You can also purchase a Windows 7 Recovery Disk from HP if you don’t have access to one yourself. This is based on your computer’s serial number, not the product key, because their database knows what version of Windows came with your PC.

Method 2

If you do not have the original disk (as you stated), or have otherwise recorded it, there is no way to get that key back. I know of no manufacturer, even if you had support, who records and maintains that.

Method 3

Simply, you will need to purchase a new product key for re-installing the OS.

Please take note;

re-installing the OS is the basic first step. Windows default drivers will not properly address your laptops hardware. You will need to acquire the drivers from HP. Yes, this can be done without much headache. You will need the make/model number of your PC and point your browser to the HP ‘downloads’ page of their support site.

I have been restoring PCs for many years(15+) and have experienced this very issue. Sadly, without access to the old hard drive, the purchase of a new product key/license is required.

Thank you for listening.

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
