What is mysqld.exe?

mysqld.exe is an executable file that belongs to MySQL Server, a relational database management system. MySQL Server is developed by Oracle Corporation and is also a part of the XAMPP package. It is also used by MariaDB Corporation Ab, a popular fork of MySQL. The mysqld.exe file is the main process that runs the MySQL server.

MySQL Server is used for managing relational databases. It is a crucial component for many web-based applications that require database functionality. It is also part of XAMPP, a free and open-source cross-platform web server solution stack package, which allows developers to easily test their web applications locally.

mysqld.exe is needed to run the MySQL server. Without this executable, the MySQL server cannot function. It is responsible for all the tasks such as managing databases, tables, indexes, users, permissions, and other important operations.

Under normal circumstances, there is no need to remove mysqld.exe if you are using MySQL Server or XAMPP. If you find that it is consuming too many system resources or if you no longer need MySQL Server, you may choose to uninstall it. If the mysqld.exe file is located in a suspicious directory or if it is causing security issues, it might be a malware disguised as the MySQL process, and in such cases, it should be removed.

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.

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.

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.

Occupies CPU 100%. Sudden occurrence. Persistent
   
This is the process of MySQL database server.
   
Just the MySQL Server running on your machine, which if you have running, likely means you installed MySQL Server and started it. MySQL is a database management software.

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 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To get your computer running as fast as it did on day one, you can 8reset your PC. Your personal files will remain intact, but any programs you installed will need to be reinstalled.

To help you analyze the mysqld.exe process on your computer, the following programs have proven to be helpful: ASecurity 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. A good Bantivirus software detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
