Windows 10: Needed help in recovering the windows product key

I have brougt a laptop with windows 7 home and later upgraded it into windows 10 pro. Currently I don't have the original CD cover and invoice which contain the license key.The windows is activated with and digital license. Its a couple of years now and I have reinstalled the windows several times. Now I wanted to transfer that key to a new laptop, with windows 11 home, but I can only find the generic key ending with 3V66t from the registry and lost the original key. Is there any ways to obtain the original key?I tried to upgrade the windows 11 with the generic key, which shows Error code

Finding the Windows Vista product key

It doesn't recognize the drive with a disk inserted? I know my systems will not show the cd/dvd drive in "my computer" unless they have disks in the drive.
