Need to check the SMBIOS version of a system - for hardware compatibility checks or firmware specification lookups? This one-liner pulls it straight from the system.

Prerequisites:

- Privileges: None
- Module: Built-in, no import needed

Quick Command:

```powershell
Get-CimInstance -ClassName Win32_BIOS | Select-Object SMBIOSMajorVersion, SMBIOSMinorVersion
```

Example Output:

```powershell
SMBIOSMajorVersion SMBIOSMinorVersion
------------------ ------------------
                 3                  6
```

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:

```powershell
$bios = Get-CimInstance -ClassName Win32_BIOS
"$($bios.SMBIOSMajorVersion).$($bios.SMBIOSMinorVersion)"
```
