How can I get a windows serial number if my laptop doesn't start?

Microsoft Windows 10 (64-bit)

I have a problem with windows boot on my machine. It doesn't restart. The solution is to either reinstall the windows or change the HDD. I have geniune windowa in my machine but I haven't noted the activation key. How can I get the key now to continue using geniune windows?

You can't get one from HP because we do not supply them.


However, if all you want to do is reinstall Win10, you do not need the Product Key as that is encoded into the firmware of the system board.  When you install Win10 and see the window to enter the product key, scroll to the bottom and select the option to skip that.  When the PC them goes back online, it will contact the MS servers and automatically reactivate.
