about the policy applying
Important Note:
Before step 2, if the target dtAgent already had File-Based Policy Settings: Load policy files imported by one of the following accounts
applied, then please don't manually copy the .dtpol file to path %PROGRAMDATA%\deviceTRUST\Policy.
Instead, please run dtcmd IMPORT /add:<filepath>
with the user account configured in the File-Based Policy Settings: Load policy files imported by one of the following accounts
setting. The command will import the .dtpol file automatically.
