System icons greyed out

My system icons icons are greyed out, like Volume and Power, so I can not enable them.
After setup they work just fine, then they disappear. It is either caused by my settings or:
I wonder, when custom power and sound card drivers gets installed, they get lost?

SFC scan does nothing. By playing with settings and closing explorer.exe, volume icon appeared and stated, that there is no audio service running, when I moved the slider, the message and red X disappeared, but after restarting explorer.exe, it was gone again. My sound card audio service, Windows audio are running.

Seems this problems happens: System Icons Greyed Out for Windows 10 - Microsoft Community

 

MS can provide updates to your hardward as you know and they sometimes overeide what you should really install. Go to the website and download the correct driver.

EDIT: Reinstalling ACPI-Compliant Control Method Battery restores power icon temporarily.
On my second laptop, all icons came back to life by itself. I do not need them on mine, so np.

EDIT 2: Volume control disappears, when I disable laptop's default sound card.
Old volume and power icons can be used, power works, sound still not though.

Reg add "HKLMSOFTWAREMicrosoftWindowsCurrentVersionImmersiveShell" /v "UseWin32BatteryFlyout" /t REG_DWORD /d "1" /f

Reg add "HKLMSOFTWAREMicrosoftWindows NTCurrentVersionMTCUVC" /v "EnableMtcUvc" /t REG_DWORD /d "0" /f

EDIT 3: My problem was caused by disabling action center, which also disabled system icons:

reg add "HKCUSOFTWAREPoliciesMicrosoftWindowsExplorer" /v "DisableNotificationCenter" /t REG_DWORD /d 1 /f

I have figured it out at last. It is all because those entries were set to low, so icons crashed or something.

reg add "HKCUControl PanelDesktop" /v "HungAppTimeout" /t REG_SZ /d "5000" /f

reg add "HKCUControl PanelDesktop" /v "WaitToKillAppTimeout" /t REG_SZ /d "20000" /f

reg add "HKLMSystemCurrentControlSetControl" /v "WaitToKillServiceTimeout" /t REG_SZ /d "20000" /f

I have the same problem.
Could you please talk me through how to fix this? I am completely in the dark...

Oooops, sorry I clicked it twice

I have the same problem.<br>

I would say, that each problem is unique, but you try this, run CMD as admin and enter:

reg add "HKCUControl PanelDesktop" /v "HungAppTimeout" /t REG_SZ /d "5000" /f
reg add "HKCUControl PanelDesktop" /v "WaitToKillAppTimeout" /t REG_SZ /d "20000" /f
reg add "HKLMSystemCurrentControlSetControl" /v "WaitToKillServiceTimeout" /t REG_SZ /d "20000" /f

Restart and you will see immediately, if it is fixed or not, if not, you will have to look for another solution.

Thank you very much for your help.
The very strange thing I am finding out about Windows 10 is that when I get so very desperate and finally get to posting about my problem, I boot up the next day and the problem is solved. I should not speak too soon though. I have crashed this laptop over 50 times for various reasons so I am asking for trouble....
