Activation key for Windows 8 on Optiplex 9010
The story is a little longer :
- upgrade from Windows 8.1 to Windows 10 - everything ok
- used for a while with Windows 10, in good conditions
- changed user, which wanted to reinstall Windows
Reinstalled windows from scratch, using original Windows 8.1 installation DVD ; installation was ok, but Windows didn't recognized the authenticity of the software and ask for a valid key. The OS is OEM, so we don't have any key for Windows.
Please help us to get Windows activated.

gb.dumitrescu,
To activate Windows 8.1 using the phone:
Select the Start button , enter PC settings, and then select PC settings from the list of results.
Select Activate Windows, and then select Contact customer support for help.
You may be asked for an admin password or to confirm your choice.
Select your location (or the location nearest you) from the drop-down list, and then select Next.
Call one of the available phone numbers listed. An automated system will guide you through the activation process.

Windows 10 Build 14393 installation media will automatically input the Windows 8 OEM Product Key embedded within the UEFI BIOS during clean installation and activate when online.
