It is the server process of MySQL database. It is an daemon process that accepts connections from the Internet, therefore it should be allowed to run only if you are indeed running a database. It is not a dangerous process on its own, however like any daemon, if you decide to run it, you should update it regulary with security updates as vulnerabilities in an unupdated daemon may expose your computer to unauthorized remote access.

it consumed 80% of cpu resources on boot
Un Essential .Exe File Causing System Slow and taking off 60-80% of System Usage

next-to-nothing but when my laptop was new it ran like a deer and now it only runs like deer is if I end the process because it consumes too much resources. It only appears on the task manager when I request all users and I am the only user of this laptop
It runs everytime I reboot. It takes up majority of the CPU, sometimes up to 96%, I tried to run msconfiq and go to start up and remove it but it's not in the list.
causing 100% CPU utilization in windows 7 64 bit
In my case, (I have a Dell and recently replaced the old unsupported Dell Remote software with their newer offering - SingleClick CONNECT), this program was installed with the new remote connection package. Yes, it does hog the system on startup but, I guess, if you want to use the software you have to put up with it. After it finishes 'doing it's thing' , it releases the resources and everything works fine. I just have to start my computer and then go have a cup of coffee, take a shower and come back and it's ready to go. Why doesn't Dell or SingleClick weigh in to explain the mystery

Windows Media Center ( and the many clones ) programs may well use this for their streams and program lists databases. Should you disable this, then you may expect that some propgrams or plgins and addons may no longer work. If you had recently installed such plugins then even after un-install, the SQL program may still be running. From Start/Run box type in services.msc and then OK. scroll down the list until you see MYSQL. Stop the service and see what programs are affected (if any). If no ill effects then double left click on MYSQL entry and set startup type to disabled.

Best practices for resolving mysqld issues

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

To help you analyze the mysqld.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. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
