Activation Windows 10 after reinstallation HP Pavilion 500 PC Series

[adrbin]

Hi, i had problem with boot into OS after Windows 10 update. HP recovery volume, or factory reset all failed.

So I created USB disk with media creator tool from Windows and reinstall OS, but Windows Key from bios doesn't work.

I don't know what to do next to activated the OS. Version of OS is Windows 10 Home and that is ok. If I try to use slmgr.vbs -ato it says Activation of product Windows(R), Core edition (2b1f36bb-c1cd-4306-bf5c-a0367c2d97d8) ... Error: Activation failed.

I think that you are "trying too hard" -- it's not as complicated as extracting the key from the BIOS, or running the SLMGR.VBS application.

My guess is that license-key in the BIOS works only when you install from the HP "System Recovery" set -- either a hidden partition on your disk-drive, or a set that you created (writing to a USB memory-stick or to a few DVD-recordable disks) from within Windows.

However, because Windows 10 was installed on your computer, you ahve been granted a "digital entitlement" to reinstall Windows 10, at no cost to you.

So, from that downloaded software on your USB stick, click "I do not have one" when prompted to enter the 25-character product-key. The next time that you have an Internet connection, Windows should "activate".
