[FIX] Nahimic Companion keeps Reinstalling

The Nahimic Companion is an enhancement of your audio driver by MSI. In many cases, this application was installed without any user interference/acceptance (by the Windows update) & shown in the system’s tray. This application is well embedded into the OS modules & thus not easy to uninstall. Moreover, if a user succeeds to remove it, the application reinstalls on the reboot. This application eats up quite a RAM of the user’s system & at times, it is not even present in the installed applications.

    \ProgramData\
    
    %localappdata%
    Delete Nahimic in the ProgramData Folder

Block the Execution of the Nahimic Companion Application

    Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies
  2. Now, right-click on the Policies key (in the left pane) and choose New>>Key.

    Block the Nahimic Companion Through the Registry Editor
  11. Then close the Editor and reboot your PC to check if the system is clear of the Nahimic issue.

Solution 3: Disable the Onboard Audio Device in the BIOS

The Nahimic companion is usually part of the on-board audio driver and if you are using an additional audio/graphics card, then disabling the onboard audio device in the system’s BIOS may solve the problem. The instructions slightly vary from user-to-user basis.

  1. Uninstall the Nahimic Companion and disable its services.
  2. Then power off your system and boot it into the BIOS of your system (you may press the F2 key).
  3. Now navigate to Advanced and open Integrated Peripherals.
  4. Then disable the HD Audio Controller and exit the BIOS after saving the changes.
    Disable Onboard Audio Device in the BIOS
  5. Now boot your system into Windows and check if the Nahimic problem is solved.

If the issue persists (even after all the hassle), then you may install the strip version (without Nahimic by deleting the files/folders related to it in the downloaded driver folder) of the Realtek driver. If that did not solve the problem, you may try a 3rd party uninstaller (like using the Revo Uninstaller in the hunter mode) to remove all the traces of the Nahimic Companion. Even if the issue persists, then you may use a code editing application to scramble the code of the EXE files of the Nahimic Companion.
