[How to get the cause of high CPU usage caused by apps?]

Thanks. Is there any way to fix it? I've ran sfc /scannow which came back with 0 issues. chkdsk passed. I don't know what to do. Turning them off is just covering it up, really. I'd like to be able to see thumbnails again.

I PM'd you the file. After using the file you posted, I could see that it (probably) has something to do with WAV files.

 

 

This makes sense because I had recently force-cancelled a MOVE operation for some WAV files. It's been doing this ever since.

Honestly, I'd rather learn it myself. It seems that xperfview was replaced with WPA. Certainly WPA, being xperfview's successor, should have no problems following this guide? I followed the guide fine up until that point in my first post.

Any chance of updating the instructions for WIndows Performance Analyzer v6.3? The reason I ask is because:

 

Now go to the graph "CPU sampling per CPU" and select the interval where you have the high CPU usage, make a right click and select "Load Symbols" and next click "clone selection". Make a rightclick again and select "summary table"...

 

Everything in red either cannot be found/is located somewhere else or is named differently. There is a graph called "Utilization by CPU" under "CPU Usage (Sampled)." The option "Load samples" only appears under the "Trace" menu. "Clone selection" isn't available when right-clicking the selection, nor is "summary table."

 

Am I just doing it wrong?
