Hi @mnothh , thanks for the submission. And sorry for the late response, as I've been on vacation. I'll get this code reviewed ASAP.

Hi @mnothh, what specific Windows and PowerShell version did you test this on? This doesn't work on my Win10 machine. I have to add -Online and -FeatureName, and also need to look at the .State property, not the .InstallState property.

PS D:\> $blFeature = Get-WindowsOptionalFeature BitLocker
Get-WindowsOptionalFeature : A positional parameter cannot be found that accepts argument 'BitLocker'.
At line:1 char:14
+ $blFeature = Get-WindowsOptionalFeature BitLocker

                   inappropriately decommissioned computers by encrypting the entire volume and checking the integrity
                   of early boot components. Data is only decrypted if those components are successfully verified and
                   the encrypted drive is located in the original computer. Integrity checking requires a compatible
                   Trusted Platform Module (TPM).

Hey @mhendric. You are likely correct. I believe this was tested on 1709(off the top of my head). I'm currently out of office as well. As soon as I have access to my test machines I'll rework this to confirm it is compatible with newer releases as well.
