Product Key

Keys are not required for the upgrade process. Windows 10 has a built-in generic key which it uses to install - it acquires the underlying Win7/Win8 activation during the upgrade process and assigns your device ID as a valid Windows 10 activated device. Subsequent installs will thus activate using your device ID. You will not require a key - should you be prompted, select "skip". Activation is automatic thereafter.

My Product Key


I have hit another roadblock in my marathon two-day attempt to restore the laptop that Windows 10 destroyed. I do not have the product key for the device, so cannot even revert to Windows 8.1. The product key is not shown in the Amazon purchase listing for the device, and I long ago lost the paperwork. Is there any way I can look it up (keeping in mind of course that the device itself is utterly unusable in its current state)?
