MySQL Server for NT Systems, is a database server very powerful. The service is secure. The risk is if not properly defined user and paswword. It can cause remote handling to your mysql databases by intruders
After installing CS2, It kept my windows XP desktop from "coming up". Computer "hung" on background pic, opened Taskmanager and noticed the related program mysqladmin.exe was running on and off, on and off... So I "Killed" mysqld-nt.exe since I couldn't "catch" mysqladmin.exe. WIndows came up like normal after that! Disabled Version Cue and everything seems O.K.!? I don't really have a need for Version Cue, so I am happy now. If you WANT Version Cue, keep looking.

Best practices for resolving mysqld-nt issues

A clean and tidy computer is the key requirement for avoiding problems with mysqld-nt. 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 repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
