HP Laptop PC 15-dw3000 (31R09AV)
Microsoft Windows 11

Laptop started in black screen. Can't do anything but to reinstall windows. I need the product key. Tried finding in BIOS, by using the command on command prompt and also tried in the path in regedit.  Unable to find. I had earlier received it online when such error took place. Now I don't remember how to find. Kindly help.
