lmgrd is the Flex License Manager. It should only be run on your local machine if you are using it as a Flex License Server. It's like a license repository for floating licenses that yours and other machines can check out. If you're using a floating license, it doesn't usually make sense to run the license server on the machine you're using to run a high end simulator or CAD program.

Best practices for resolving lmgrd issues

A clean and tidy computer is the key requirement for avoiding problems with lmgrd. 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, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the lmgrd.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.
