I was trying to find a way to bring back the Dell bios version, but in the friendly format of Axxx for the older versions.
a lot of people are running a select statement from the SMBIOS but it would only bring back the actual numerical version, not the Dell friendly version of Axxx for older system, so this is what I came up with to just pull it from the registry value. hope someone finds this helpful for them.
Value "BIOSVersion" of key "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet\Control\SystemInformation" of registry
