title: Take desktop screenshots in a Jenkins Build Slave during Selenium Tests
body: <br>
  I have some problem with Jenkins and Selenium. <br>
  I have a Jenkins Master and some Build Slaves, installed as Windows Services on Windows Server 2016 machines, in which I perform build jobs. In some of these jobs, I perform test with Selenium and I need to take some screenshots of these tests, but all the screenshots that I got are black. <br>
  Reading on the web, I found that many people are facing this kind issue. But I also found this, https://www.coretechnologies.com/blog/windows-services/interact-with-desktop/, in which is reported that it's not allowed for Windows Services to interact with desktop. <br>
  So, the question is: it's possible to make interact Jenkins Slave Service with the desktop in order to take some screenshot of it?
