https://community.hpe.com/t5/windows-server-2003/windows-activation-problem/m-p/5050779#M7102 I have installed and activated the Windows 2003 R2 SP2 Standart Edition trial version on the server. I has bought the OEM Windows in the box. I cann't change product key now. I do all as discribed in the Microsoft's article 918342. But the system remains activated after the OOBETimer registry value was changed.
