I am doing without RDTHCPL in the startup procedures in the HKCU\Software\Microsoft\Windows\CurrentVersion\Run path. Everything about my sound is still running just fine, since I never have a need to change any features of my sound quality.

This is the Realtek HD Audio Manager

Ad aware does not pick this, nor does virus scanners. This file attaches to sound or video executable's/services and redirects your google search's to random pages. The only way to stop this is to locate the infected service in task manager then search their locations out and delete and replace the actual files with clean one's also make sure before that to stop the startup in msconfig.exe but make sure you activate it once the clean file is in.

Running the Realtek Audio Manager under Win XP is what's responsible for creating the two dozen or so ".bin" files in your Local Settings Temp folder, one per supported language.

Realtek HD audio control panel.
   
if this file is in c:\windows directory of winxp, it is a duplicate and a malware program. It idled all the processes running on my computer and until I renamed it, I could not get a malware scan to complete. It foiled at least 5 free malware programs by idling them before they could detect the malware. I was able after renaming the file to complete a normal malware scan.

Best practices for resolving rthdcpl issues

A clean and tidy computer is the key requirement for avoiding problems with rthdcpl. 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 rthdcpl.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.
