I just downloaded the free version and cant find an answer..  

 

Is it possible to see - on my Android phone - using the PCM Android app - if the PC I'm monitoring has its "monitor/screen hardware" either on or off??  And while I use that PC remotely to lock them out of "my Win7 user profile" ????

 

I have the problem that other people at the remote location jump on and mess around when I'm trying to remotely connect - I want to shut them down remotely....  Somehow lock the PC...

 

I hope so...

Go to the Users section for that computer in your Android app and select the user you want to log out.
