Windows 10 licence key

[Nordan]

I have accidentally erased the operating system om my notebook and i wonder how to obtain the product key for Windows 10 which is pre installed from the factory?

I don´t have a recovery cd or a usb but I have downloaded installation files from a another computer from Microsoft, but i get stuck in the installation process. It cant find a partion to install it to or create one but i can see that it already i 3 partion in the computer which two contain a recovery from either HP and Windows.

Can someone help me??

Hi
ShowKeyPlus from the Microsoft Store (probably the best choice).

It gives this…. – CD Key: 12345-67890-09876-54321

ELSE
There is a possibility of finding the same value in the Registry....
USING RegEdit the key is listed below and it’s content also shown.
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform

BackupProductKeyDefault 12345-67890-09876-54321

Three different names for the same value in 3 different software methods.

This part only works when a valid Recovery Partition is enabled.

Disconnect all connected devices and cables, Media Drives, USB drives, printers, & faxes.
Remove media from internal drives, and remove any recently added internal hardware.
Do not disconnect the monitor, keyboard, mouse, or power cord.

Turn on the computer and repeatedly press the F11 key, about once every second,
until the Choose an option screen is displayed, and then continue.

On the Choose an Option screen, click Troubleshoot, and work your way through the screens.

If in doubt please ask.
