I am trying to determine if BitLocker is updated. All I can find on BitLocker is if the service is running as in:

```
Get-Service -name "BDESVC*"

```

Usually the `gwmi -class Win32_SoftwareFeature` will return all applications versions but BitLocker isn't there. Does BitLocker need updating? Is it stored somewhere else?

I am using Win7 64bit PowerShell v2
