Performance Optimizer is a wonderful Discovery btw....Props to you guys for that feature btw.
but on using it once to sleep some programs especially steam......and then when i uninstalled and reinstalled ccleaner due to some issues, i couldn't wake steam up as it was showing that it was slept by external application but ccleaner was the one which previously put it into sleep.
Due to this i uninstalled ccleaner and my steam was not launching again after that, this led to me resetting my PC and all this was too much of a hassle kindly fix it.
