Anyone utilizing nvidia graphic cards will have this program running. While it is not needed it does provide a consent search for updates for the drivers to run your graphic cards. Recommendation, keep it but turn the service off.

Got error "RunDLL c:\windows\system32\nvsvc.dll The specified module could not be found." Only reinstallation of Nvidia Graphics Driver helped.
We have multiple (over 450) Nvidia installed cards in our company and it seems to cause no end of problems with it using 50% of processor constantly. I have disabled the driver helper service on each one I am called to and have had no problems since.

Best practices for resolving nvsvc issues

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

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.
