请问如何使用powershell查询保存在AD中的Bitlocker recovery key? 好像AD模块里面没有相关的命令？

我这边没有AD的环境，在网上找了一个，请帮忙尝试：

# Get Computer Object
> $computer = Get-ADComputer -Filter {Name -eq 'WIN7X86PC01'}

# Get all BitLocker Recovery Keys for that Computer. Note the 'SearchBase' parameter
> $BitLockerObjects = Get-ADObject -Filter {objectclass -eq 'msFVE-RecoveryInformation'} -SearchBase $computer.DistinguishedName -Properties 'msFVE-RecoveryPassword'

# Output the results!
> $BitLockerObjects
