BSOD - How do I retrieve Windows Key from an old SSD drive?

[Guest Phil Marion]

My 11 year old computer will not boot due to "Bad System Config Info". I've tried System Restore, tried Resetting This PC, tried restarting in safe mode but no joy. I have just completed a new pc build with an Intel i7 13700 and a Z790 motherboard and would like to install Windows 11 on to it. How do I retrieve the Windows 10 product key? It is on a 2.5" sata SSD and I have a SSD external enclosure that I have used to gain access to my non-Windows files using a laptop.And if I can retrieve the W10 key, can I use it to upgrade to W11? Do I boot W11 on the new machine and use the W10 product key
