Windows 10 won't go to sleep after recent fall update

Absolutely nothing to do with the forbidden tana leaf.

I too had a similar issue. I'm posting because this thread is one of the top results Google gives for Windows 10 sleep problems.

The solution that worked for two computers I had that were not sleeping was as follows:

• Run an admin command prompt
• powercfg -requests
  • This command lists all processes or services currently running that are preventing the computer from sleeping. The list is helpfully broken down by categories. One of my affected computers had sleep blocked by the IncrediBuild component of Visual Studio, the other by a different TSR program.

Would Windows Search be preventing sleep timer?

I can manually enter sleep, just not via timer set in power options.

C:\WINDOWS\system32>powercfg -requests

DISPLAY:

None.

SYSTEM:

None.

AWAYMODE:

None.

EXECUTION:

[SERVICE] \Device\HarddiskVolume6\Windows\System32\SearchIndexer.exe (WSearch)

Windows Search is indexing

PERFBOOST:

None.

ACTIVELOCKSCREEN:

None.

This problem has self-healed itself for me. But a question with regards to Paul's findings with the following: 

EXECUTION: [SERVICE] Device\HarddiskVolume6\Windows\System32\SearchIndexer.exe (WSearch) 

Windows Search is indexing

If perchance this is an issue, how would one stop that execution? What scares me with this thread, is the vast amount of replies rolling in. Should we expect a reply anytime within the next two to three years?

For those who do not see this question, those ones should contact the moderator immediately.

I did this and found this:

I did some checking and those drivers listed under SYSTEM is my USB headset (HyperX Cloud II); it says "None" when I unplug the headset. Although, I don't understand why this would be preventing sleep.

1. The "allow computer to sleep" under the multimedia section, as many have talked about here already, is selected.
2. This problem hasn't occured until recently. I have had this headset for almost 2 years and only now is my PC having an issue with sleeping after idle (been using Win10 the entire time as well).
