Anytime you have a different sound card installed, some drivers are retained, do not delete if you still have realtek installed. If infected, find reinstall and delete original if no other source can be found.

Lately my computer started freezing up to a point I had to totally shut it down and reboot it,I even changed internet browsers, I ran several different spyware and registry cleaners, nothing worked. I found this file some how got in the "Start Up" list a few days ago, since I took a photo of everything needed in the start up menu with my camera when my computer was running good I knew ALCXMNTR.EXE did not belong there. I did remove it from the start up and c:\windows\ALECMNTR.EXE.

This file runs your sound. I screwed with it and now my sound will not work. Leave LCXMNTR.EXE alone!!!

Well, I deleted it, and my sound still works, so I don't see the point in having it eat up my V-Memory.

Realtek AC97 driver. Let it be.
   
Even tough it's disabled in MSConfig and stays unchecked, it is still running. You can use Task Manager, www.pcpitstop.com or EndItAll to see that it is still active. I have no idea what is causing it to start up.

Best practices for resolving alcxmntr issues

A clean and tidy computer is the key requirement for avoiding problems with alcxmntr. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the alcxmntr.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
