使用PowerShell确定Bitlocker版本

Question

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

Answer 1

After some lengthy searching, I found manage-bde . This command works great with the command line and PowerShell. I still am having an issue with pulling just the version number though.

Answer 2

Yes, this is the only option available for checking the version as the application isn't standalone. On Max OS X, it is the same. The version isn't made obvious or available.

Answer 3

In case this helps some one now, you can use the following command to extract the required information for your purpose.

Command

manage-bde -status C: | FINDSTR "\<version"

Result

BitLocker Drive Encryption: Configuration Tool version 10.0.15063

Please don't forget the '\\<' because this is used to filter out the version, else other data containing the word 'conversion' also gets populated.
