I lost my Product key, How can i recover it

[Hrushi3]

I was trying to upgrade my pc to tiny 11 os, and it backfired, so then it booted me to windows 11 enterprise, while I had windows 11 home. Where can I find this lost product key.

If your notebook came with Windows Home, the product key is encrypted in your PC's BIOS.

Install the free Showkey Plus app from the Microsoft Store and it will show you the Windows OEM product key and the version of Windows the key is good for.

That's not the issue, when i installed tiny 11, another key got installed onto the laptop, and I lost the original key, so I am asking if there is a way to find that key.

It is the issue.

You will find the original Windows Home OEM product key when you run the showkey plus app.

Otherwise, just use the Media creation tool to make a bootable USB installation flash drive to reinstall W11 (2nd option).

Download Windows 11 (microsoft.com)

It should automatically reinstall W11 Home.

I already have windows 11 installed, and I downloaded the app, so where is the key?

[Paul_Tikkanen]

You have to run the app.

This is what it should show, because I have run this many times on many different PC's.

For example:  This PC I have originally came with W8.1 Pro and I upgraded it to W10.

The last two lines of the report are what you need to know.

ShowKeyPlus - Windows Product Key Information

Product Name: Windows 10 Pro

Version: 18362.657 (64-bit OS)

Product ID: 00330-80000-00000-XXXXX

Installed Key: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

OEM Key: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

OEM Edition: Win 8.1 RTM Professional OEM:DM

If you don't see the last two lines I bolded on the report then you have a major problem, as the product key and version of Windows has been wiped from the BIOS somehow, if your PC originally came with W10/W11 Home from HP.

PC's that come with FreeDOS from HP have no product keys in the BIOS and the user is responsible for providing their own Windows product key.
