By default, the base instance Windows OS - Servers pattern and windows OS- Desktops returns the baseboard serial number. But in some cases, the user might want to use the BIOS serial number for the CI instead.
Steps to Reproduce
Run Discovery on windows server using patterns.
The main CI's serial number field will have the baseboard serial used, instead of BIOS serial number, which will be incompatible with what other plugins that populate the CMDB are doing, such as SCCM.
