WIN 10 Activation after BIOS Update

[Duffers]

I've just taken dleivery of my new Z4 G4.

Boot up was fine.

Win 10 64 Pro Workstation updated itself.

updated the BIOS using the latest version from the support page.

then noticed windows will not self activate...error code 0xC004C003...in short wrong product key

any help or similar issues with BIOS updates messing up linkage between digital license key and activation???

which version of windows did the workstation come with

regular windows 10 prof, or win 10 for workstation

if win 10 prof, it will self activate once connected to the internet,

(you do not enter a key at the prompt for the key if asked)

if it came with win 10 prof, and was upgraded to win for workstation

you will need the activation key that came with  win for workstation

Came with Win 10 64 Bit Pro Workstation pre installed from factory on the Z turbo drive
