I have trouble disabling the screen saver from HP Thin Client t730.
We are using Win Server 2012 R2 Datacente.
I already found your instructions for WIN 7 and WIN 8.

I tried to do the same. I changed the ScreenSaverActive 0 --> 1 from registery editor, but after that I was unable to commit to EWF. I'm guessing that it is not possibe to do with this Windows, because I could not reach EWF even with command prompt.
