How to view apps preventing sleep on Windows 10
Understanding results
The results aren’t presented in the most user-friendly format; such is the nature of information you’ll get from command-line tools. That said, here’s a simple breakdown of the information you might see.
- Display: This will show processes that have taken over the display e.g. an app in full-screen mode. This could be a media player like the Movies & TV app, or it could be presentation software like PowerPoint. It could also be a screen recording tool like OBS.
- System: This will show system processes though the system processes may be invoked by other apps that are running. For example, if an audio stream is playing, the audio driver will be in use and will appear to be preventing the system from entering sleep. You will normally be able to see which apps are using the audio device on your system so quitting it shouldn’t be too hard.
- Awaymode: This will show apps exclusively. It’s a command that apps send to Windows 10 telling it to keep the system awake. Apps can programmatically do this.

A few days ago I noticed that my PC no longer goes to sleep based on inactivity (although I can manually put it to sleep). Today I ran "powercfg -requests" and saw
EXECUTION: [PROCESS] \Device\HarddiskVolume2\Program Files\rempl\sedlauncher.exe SleepDeferralConditionsMet PERFBOOST: [PROCESS] \Device\HarddiskVolume2\Program Files\rempl\sedlauncher.exe SleepDeferralConditionsMetSedlauncher is apparently part of Windows Remediation Service and, from scattered reports on the web, think it may have been part of KB4023057 that I installed about 2 weeks ago.
