If you leave them Windows 10 in idle, without doing anything at all, they will eventually be put into sleep mode. This is a system default where you do not need to set anything, although you can adjust the idle period or when the system is idle.
In order not to put into operation a system of Windows 10 is not just required to have some user activity. Background applications and processes can prevent the system from shutting down. Unfortunately, there is no simple GUI-based method for viewing applications that block this process in Windows 10. However, you can use a simple command line command to do your job.
To see which applications prevent a system from being suspended, you need administrator privileges. This is because the command will look at the instructions sent in the operating system power management policy. Let's see how:
1. Open the command prompt with administrator privileges.
2. Execute the following command as it is. Do not change anything.
powercfg / requests
The command will return a list of processes and applications that block their entry Windows 10 in suspension.
Understanding the results
The results are not presented in the most user-friendly format. To understand them consider the following:
Display: This section will show the procedures that have taken over the screen, e.g. an application in full screen mode. This could be a media player such as the Movies & TV application or it could be presentation software such as PowerPoint. It could also be a screen capture tool like OBS.
System: It will show the system procedures, although these procedures may be called by other running applications. For example, if an audio stream is playing, the audio driver to be used will appear to prevent the system from entering sleep mode. You will usually be able to see which applications are using the audio device on your system, so shutting down should not be too difficult.
Awaymode: This section displays applications exclusively. It is a command that applications send to Windows 10 and tell him to keep the system awake. Applications can do this through programming.
Some applications are designed to prevent shutdowns from working properly. The suspension of operation will not prevent the system from locking, but while the system is awake, all the application needs e.g. edit a file, you will still be able to do it.
