SQL Server 2008 Official version of the installation Guide contains serial number _mssql

If you do not have a serial number, then you can only select one of the three free edition (Enterprise evaluation, Express, Express and Advanced Service) above. If you fill in the serial number below, the SQL version corresponding to this serial number is installed, which is similar to Windows Server 2008.

In the installation program dvd, the serial number provided by default is determined by the contents of this file:

Its contents are as follows:

Reference:

; SQLSERVER2008 Configuration File
[SQLSERVER2008]
pid= "***xx-***xx-***xx-***xx-***xx"

As long as we replace the serial number we own with the pid=, then in the course of the installation, we will Microsoft
