Hi I recognise the way the last time I posted this was done the wrong way so I will post a summary of my issue and what I did to fix it. If its a thought that this is unique to my system I am happy to provide information on my system. So a summary is that with afterburner 126.96.36.19953 on a windows reboot, afterburner will fail to respond to the OSD hotkey. However if I close and relaunch afterburner it works absolutely fine until the next reboot. I today started debugging the problem, and have it now behaving on my system, since afterburner rewrites the task in task scheduler everytime its fired up these are the steps I did. 1 - Disable run on startup in the afterburner settings, this prevents the startup task from starting afterburner, I discovered specifically this prevents it from been started with the /s switch. 2 - Duplicated the task, and on the duplicate task I removed the /s switch, and made one simple change to the startup trigger. 3 - Startup trigger I set delay task by 1 minute (on the run on logon of any user). This solved the issue, it seems its related to it starting too early.
