How It Works:
- Get-CimInstance -ClassName Win32_BIOS queries the Win32_BIOS WMI class, which stores information about the BIOS/firmware installed on the system.
- Unlike a single combined version string, SMBIOS version is split into two separate properties - SMBIOSMajorVersion and SMBIOSMinorVersion - so a result of 3 and 6 means SMBIOS version 3.6.
Pro Tip:
To display it as a single readable version string instead of two separate columns:
$bios = Get-CimInstance -ClassName Win32_BIOS
"$($bios.SMBIOSMajorVersion).$($bios.SMBIOSMinorVersion)"
