If Anyone is interested in the same Function, here is how i did it:
First of all i created 2 Batch files
GoverlaySleep.batcd "C:\Program Files (x86)\GOverlay_v163\"
GOverlay.exe -activateprofile3.5 "idle (LCD2)"
GoverlayWake.batcd "C:\Program Files (x86)\GOverlay_v163\"
GOverlay.exe -activateprofile3.5 "gaming (LCD2)"
Through to Windows System Restrictions you need to allow the Annoying UAC every time you start the Batch files.
To Bypass the UAC you need to add 2 Tasks in the Task Scheduler. I named them "Goverlaysleep" & "Goverlaywake" like the Batch Files.
Make sure to Check "Run with highest privileges". We dont need to add a Trigger. As Action we add the Batch Files.
The first step is done. If you Run the Tasks the Goverlay changes the Profile without the UAC.
_________
The Second step is to build a "Software-Switch" to Toggle the Profiles.
Therefore i also build a Batch File:
GOv-DisplayToggle.batif exist "1.txt" GOTO SLEEP
schtasks /run /tn Goverlaywake
echo Goverlay Eingeschaltet>>1.txt
GOTO END
:SLEEP
schtasks /run /tn Goverlaysleep
del 1.txt
:END
This File checks, if the 1.txt exists. if not, it starts the Sleep Task and Creates the 1.txt in the Folder.
if the 1.txt exists, it jumps over to the Wake Task and deletes the 1.txt. so this could go on endlessly.
________
The last step is to bind a Key to the Batch. To do that, create a Shortcut of the "GOv-DisplayToggle.bat", put it on the Desktop, right-click it, select Properties and click on Short Cut. Now Press the key you want and apply. Close the Properties Window and Test if it works.
