I use it for a National Instrments Data Acquisition card. It allows for using the NI program to change the states of a NI-DAQ card.

National Instruments Labview file, resides in system32 folder
Necessary for National Instruments Hardware setup and control, if you do not use their hardware or LabVIEW-Lego software, should be safe to disable/remove.

Suspect it is a labview component, since others mentioned labview, and I have labview. Association with Lego Mindstorm probable, since LMS contains labview components.

Best practices for resolving nipalsm issues

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