If you want to turn it off once:
Task Mangager > find Mysqld.exe > right click it > End Process
If you want to turn it off for good (meaning it won't run when you start the computer):
Start > Run > msconfig > Startup > find it in the list > uncheck it > click OK > (may have to restart)
I recommend doing the second one especially if you aren't using it and if its that much of a hassle.
Hi, my dad has a new Dell Inspiron 518 Desktop running vista 64, and is running very slow. I ran task manager and did not see an issue. but when I reviewed resource monitor it showed Mysqld.exe running most of the CPU usage averaging 70%. I cannot find it on the computer by running an advanced search(showing all system and hidden files). Can any one give me an idea of how to stop this process? any help would be appreciated. I don't even know what this does, very little info out there on this other then it might be some type of database a program would use.
