Registry Resets values after reboot.

Chandlerw · 27 Apr 2020

So I've had this issue the entire time that I've had this computer. The first issue was that my speakers would make a loud pop before audio and a loud pop after audio. And to fix it what I did was go into system registry, go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96c-e325-11ce-bfc1-08002be10318}\0003\PowerSettings and I changed the ConservationIdle time to 00 00 00 00 as well as the IdlePowerState and PerformanceIdle. I did that for all the audio settings and the rest of those saved and haven't been reverting to different values. That fixed the issue for a few weeks and all was good. However, recently I unplugged my speakers from my laptop and the values in the registry reset themselves. Now I try to edit it back to 0 but it keeps resetting itself to the default values every time I reset the device. I have no idea why this started happening and I don't know how to fix it.

Many Registry entries are set by other Registry entries at bootup / user logon. So what might be happening is that your Power plan is overwriting the Registry key you refer to and that's why you lose the values you want.
- I do not have the set of Registry keys you refer to [presumably they are hardware dependent].

Are the entries visible in the properties of your power plan?
PowerCfg -Qh >"%UserProfile%\Desktop\PowerPlanProperties.txt"
Choose your own output folder path.
See View All Power Plan Settings in Text File - TenForumsTutorials for a detailed explanation.
- I always paste that txt file into Excel because I find it easier to browse around it that way.

If the properties are there then I suggest that you use PowerCfg to set the values you want.
- PowerCfg is a bit of a pig to get the hang of.
PowerCfg - SS64
Powercfg command-line options - MSDocs
- Once they are set as part of a Power plan then they will also be shown in the Power plan Registry entries

Code:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\User\PowerSchemes

Do let me know how you get on. If the parameters you want are in the properties of your power plan then I think I could talk you through using PowerCfg to set them.

I think I figured it out. It had to do with the permissions on the registry editor. So I would change the values and they would be reverted every time that the system restarted. But when I denied the system to have access to the files that I was changing and only allowed the system to be able to read, they no longer reverted back to the values that they used to be and now they're holding.

By coincidence, that was the solution I suggested to somebody else only yesterday.

Thanks for letting me know.
