Windows 10: OneDrive Personal High CPU Usage, Not Syncing

Hi everyone!

I have an issue that keeps popping up and I can't seem to figure out. Every so often, usually after I used the computer for an hour or so, OneDrive will start really taxing the CPU (25-35%), but also it won't be syncing anything. Right-clicking the notification icon and exiting doesn't actually exit the process; I have to go to Task Manager and force it to stop.

When relaunching OneDrive it's fine for a while, but then starts the same behavior again. Something is getting stuck, but I don't know how to check what's causing it.

Any thoughts on what might be causing that and what I might do to fix it? Running Windows 10 Pro on a Surface Pro 3.

Thanks!

:)

 

RuntimeBroker consumes high CPU while running GrooveMusic

As of the latest Groove update (version 10.16092.1031.0), this high CPU usage problem has mostly gone away for me. RuntimeBroker will use a lot of CPU for a short period of time after Groove starts up (as its syncing the OneDrive library), then it will stop
using the CPU and playback will use minimal CPU power. Even if I minimize the Groove app, CPU usage still stays low unlike before this update. This update allows me to minimize Groove, enjoy my OneDrive library, and not waste CPU power and battery life.

I observed this both on my desktop and my Surface Pro 3, both running fully updated Windows 10 Anniversary Update.

 

RuntimeBroker consumes high CPU while running GrooveMusic

How long does the high CPU usage last? Runtime Broker has high CPU after I start Groove, but it stops after about 3 minutes and goes to idle. Not minimizing Groove has allowed me to continue having my OneDrive music synced in the offline library. Your workaround
is perfectly fine, but on both of my machines my workaround has allowed me to keep my OneDrive Music folder in the offline library without completely draining my battery.

I suspect that the Runtime Broker activity is related to a background task in Groove. Minimizing Groove places it in the background and starts the OneDrive sync tasks which uses up a lot of CPU time. This is something that Microsoft needs to fix, but I think
a decent workaround is to not minimize the app.

 

Did a full format of the PC last night and got everything up and running again.

And it happened again. Any thoughts at all? Is there a log somewhere I can check to see what might be causing OneDrive to get hung up?

Thanks!
