TL;DR - The process "audiodg.exe" is eating up 30-40% of my CPU at all times, the common solution found online does not help.

Hello there.

I was recently noticed substantial lag from my laptop. While in Task Manager I see that 'Windows Audio Device Graph Isolation' (audiodg.exe) is running constantly, and consuming more than a third of my CPU resources. It runs at startup and continues to run for as long as the system is on.

This is the (or a component of the) primary audio engine, and cannot be turned off/disabled - there would be no sound. The lowest it consumes is roughly 30%, and it bounces around up into the low 40% range every few seconds.

From many, many forum searches, I see this issue is several years old, but with no solution that has worked for me. The solution offered is to 'disable all enhancements' in the audio properties panel. I had none on to begin with - every thing there is unticked. No enhancements are running at all.

There 'appeared' to be a hotfix associated with the problem (Windows6.1-KB981013-x64.msu), and I have downloaded two instances of this from seperate sources - one from the official Windows site, and another off site when that didn't work for me. I get the same error from both;

"Installer encountered an error: 0x80096002 The certificate for the signer of the message is invalid or not found."

I read that this is "caused due to misconfigured system files in your operating system. You get this error code when you try to install an incompatible software or a driver onto your PC". No idea of the validity of that claim, but they recommended running it compatibility mode for 7, which I tried, to no avail. Same error. Also, I appear to have no updates available via Windows updates (I mention that just in case that hotfix might have been included in a Win 10 update).

So that's where I stand. A fairly well known issue that is rendering my (admittedly cheap) laptop mostly unusable at the moment. Any suggestions would be much appreciated. Thanks!

  • After install Click Options.
  • Go to monitoring.
  • Uncheck All Monitoring items.
  • Go to advanced -- Click close program after cleaning.
  • Go to settings -- click run ccleaner when the computer starts.
  • Now that you have ccleaner installed and set-up:
  • Open the program.
  • Go to Tools
  • Go to Startup
  • Now double click each item. To Disable.
  • Leave only your antivirus enabled.
  • Then disable All items in your scheduled task as well.

Step 2: Optimize Service

Download easy service optmizer, save it to your desktop and unzip it there. Right click it and run as admin, then select tweaked at the bottom. Then click on the rocket, this will turn off a lot of useless items.

Step 3: FRST logs.



Please download the FRST 32 bit or FRST 64bit version to suit your operating system. It is important FRST is downloaded to your desktop.

If you are unsure if your operating system is 32 or 64 Bit please go HERE.

Once downloaded right click the FRST desktop icon and select "Run as administrator" from the menu"

If you receive any security warnings, or the User Account Control warning opens at any time whilst using FRST you can safely allow FRST to proceed.
FRST will open with two dialogue boxes, accept the disclaimer.

  1. Accept the default whitelist options,
  2. If the additions.txt options box is not checked please select it.
  3. Then select Scan

Frst will take a few minutes to scan your computer, and when finished will produce two log files on your desktop, FRST.txt, and Addition.txt. They will display immediately on the desktop, but can be reopened later as a notepad file.
