Windows 10: What does the number after "Powrprof.dll" in the registry mean?

The registry
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\PowerSettings
when searching for 'FriendlyName'
it will shows a lot of entries, reading like:
SystemRoot%\system32\powrprof.dll,-122,Allow Standby StatesSystemRoot%\system32\powrprof.dll,-561,Allow System Required PolicySystemRoot%\system32\powrprof.dll,-107,System hibernation timeout

Q: what does the number (-122, -561..) mean?

Assume
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings
is the same as 001 ?

Reason behind this question:
When turning off the screen of the laptop using a hotkey, it will go on again, after about 2,5 minutes
(when I use the hotkey again then, it remain turned off)
So I assume some kind of counter/timer is triggered so the screen turns on after given period of inactivity.

The usual settings (Control->System->Powerplan) they are okay, meaning that the screen should turn off after 1/2 hour of inactivity (on battery), 1 hour on AC.
There is nothing strange there

So I was wondering whether the number after powrplan.dll might have something to do with it.

Thanks.

DLL Missing

The problem is, that the required DLL is not actually even listed there.
There are just dozens of download adware links from the top to the bottom.

 

Accessing the DLL and Registry

I'm not sure what you think 'the DLL' is but whatever you have in mind is mistaken. There is no such thing as the DLL.

Actually there are thousands of .DLL files, each with a specific purpose. DLL stand for Dynamic Link Library, each .dll file is a library of executable code providing functions that can be called by other programs and code. There is nothing there for a human to read.

To list all the DLLs that Windows uses, open a command prompt and type the command: dir C:\windows\system32\*.dll

This produces a list of 3242 File(s) for my machine. Now, which one is the DLL you want to look at? For further understanding of what a DLL is (and what it is not) read the Microsoft link Berton gave you in post #2. For a less technical view, read: Lifewire - What Is a DLL File? (Dynamic Link Library)

The Registry is another matter, that is readable (and editable) using Regedit. However, it is rather opaque reading and the fact that any changes you make in Regedit are effective instantly (there's no 'Save' option that you can back out of, you are modifying the system as it runs) it is best not to look unless you know what you are doing.

 

DLL Missing

I actually posted the link for the "list of troubleshooting steps to resolve your boost_threads.dll problems" which is located half way down the page. I did not mean to promote any downloads.

Why don't I just go back and indicate that on my original post? That way there's access to the 'step-by-step' instructions, which are accessed via those green 'plus' signs next to the topics.

If the link still needs to be removed, then let me know
