How can I disable the unsafe volume warning?

Not personally replying to you but to the thread in general... Why don't they have a "reply to thread" button is beyond me.

In any case, just sharing my experience as it may help someone.  I tried to use the non-Realtek drivers from windows but it isn't fully compatible as my headphone jack doesn't work any more.  I have a Samsung NP700Z7C btw.  So I had to go back to the Realtek drivers.  However, when I went to Update the Realtek drivers, I noticed that my old Win 7 drivers were still there (I did an upgrade to Win 10) because I see the date is 2012.  So I selected that, and bam, no more nag pop up, and everything, including the headphone jacks, work!

Procedures:

Open Device Manager, open Sound, video and game controllers, right click on Realtek High Definition Audio and select Update Driver Software. Then "Browse my computer for driver software", then "Let me pick form a list of device drivers on my computer."

Then I selected the driver with date 2012.  However, if you upgraded from windows 8, and you had the nag there, then I don't know if it will work.  I then Deny System access to the Realtek folder in Program Files so windows/SWupdate can't update it.

The Realtek driver version is: 6.0.1.6716 [8/28/2012]

Hope this helps someone!

This didn't work for me on a Samsung Notebook 9 -- after Step 5, there's no sound device installed at all, so could not find and update any driver. Was able to revert just by changing the Properties so that System can make changes.

I had this same problem. Found out it is a Realtek driver issue, not Microsoft. So if you have Realtek loaded anywhere on your computer--i.e. systems folder, that is your bad boy.

Turns out it has to do with some EU regulation standards and it really sucks! I found the fix and solution on this page: http://www.noach.one/technotip/idiotic-realtek-audio-drivers/

That should do it, it worked for me.

There is absolutely NO THIRD PARTY software involved in this; it's a Microsoft "big brother" programming thing.

I upgraded from Win 7 to Win 10, and I use my laptop as my home computer. I always have headphones on, so as not to disturb anyone else in the house (I pretty much live in my room). Because of this, I too constantly have to click off the "high volume" warning--it is always fixed-set by Win 10 to 42%.  What is really annoying is, if I happen to lock my screen if I leave the house, or close the lid, when I return and log back in, unlock the screen--whatever--I have to RESET the volume because it went BACK to the 42%! It is incredibly ANNOYING.

Download 6.0.1.6699 (for instance, worked for me):

Then follow this tutorial which shows how to block hardware updates, inspecific the Local Policy Group Editor:

It should be relatively straightforward, but just to add:

Right click on the Realtek Audio device, under Sound video, audio and game Drivers in Device Manager.

Then go to Hardware IDs, copy and paste the two (or more IDs) into Local Policy Group Editor.

1. Make sure to get the Hardware ID before uinstalling Realtek 6.0.1.7xxx, save them in a txt file.
2. Uninstall Realtek, restart computer
3. Reinstall Realtek 6.0.1.6xxx, DO NOT RESTART!
4. Then Paste in the hardware IDs and enable Local Policy Group Editor. Now you've locked 6.0.1.6xxxx
5. Restart Device
6. Enjoy

Hope that works!
