Help recovering original Windows 10 product key from my Dell G3 3579 laptop
Hello everyone, A few years ago, I bought a Dell laptop that came with Windows 10 preinstalled and already activated. Later, I reinstalled Windows and unfortunately forgot to back up the original product key.
I’d like to retrieve the genuine Windows 10 key that originally came with my device. Could you please advise whether Dell can provide this information or how I can recover it from the BIOS or my Dell account?
Thank you in advance for your help.

Hi
This is somewhat rhetorical...
W10 Home Key aaaaa-BBBBB-11111-22222-a2zed
#################
ShowKeyPlus - Windows Product Key Information
Product Name: Windows 10 Home
Product ID: XXXXX-0000-00000-AAOEM
Installed Key: aaaaa-BBBBB-11111-22222-a2zed
OEM Key: AAAAA-BBBBB-CCCCC-DDDDD-EEEEE
OEM Edition: Win 10 RTM Core OEM:DM
###########
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform
BackupProductKeyDefault aaaaa-BBBBB-11111-22222-a2zed
##########
The poser is that there is a
W10 Home Key:
Installed Key:
BackupProductKeyDefault, I cannot find an original, and that all 3 are the same.
Why 3 different names for the same thing (just a thought, not a serious question)?
However....
KeyFinderInstaller may help.... https://www.magicaljellybean.com/keyfinder/
Doing research, and none of the methods are mine, I have some, simple single lines of code that will list the same value for your Windows 10 Product Key ......
Two for Windows 10 and one for Linux.
To find the Windows Product Key embedded by the OEM in your BIOS,
simply open a CMD windows as Administrator and issue the following command from the prompt: (or WinKey + R and type -- cmd.exe pause -- to get the screen to open)
wmic path SoftwareLicensingService get OA3xOriginalProductKey
Run from the C:\Windows\system32 folder.
C:\windows\system32\wmic path SoftwareLicensingService get OA3xOriginalProductKey
In Windows 10 you can cut and paste the command into your command window.
Next is a PowerShell command, as Administrator...
(Get-WmiObject -query select * from SoftwareLicensingService).OA3xOriginalProductKey
but it will run within W10 using cmd.exe as an Administrator.
powershell (Get-WmiObject -query select * from SoftwareLicensingService).OA3xOriginalProductKey
Last, but not least....
Linux@Lubuntu:~$ sudo cat /sys/firmware/acpi/tables/MSDM | strings | tail -n 1

As long as Windows 10 was successfully activated on that machine in the past, or it originally came preinstalled with the system, then you don't need a product key. It will automatically activate once it detects an internet connection. If you are reinstalling Windows 10 using the ISO image from Microsoft's website, all you have to do is select "I don't have a key" during setup, and then select the correct edition (Home, Pro, etc.) that was installed on the computer. (The product key, if entered, will select the correct edition that it is tied to).
