Windows – OLicenseHeartbeat.exe and how can I prevent it from running

office365windows

A few days ago, Windows started running the process OLicenseHeartbeat.exe (Office Subscription Licensing Heartbeat) every day at a certain time.

I'm not sure what it does. And the worse thing is it's killing the CPU. It consumes so much that the CPU Reaches 100% utilization.

What does this process do? Is there a way to stop it from running?

  • It's a scheduled task that is set up during Office install. There is a service that the task manually executes at certain times.

    If you go to the Task Scheduler you should be able to find it and disable it (or go to services.msc and disable the service it executes), although I'm unsure of what side effects maybe encountered.
