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.

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

it is the successor, but a complete new tool.
Copy the attached file to the same folder where the latency.etl is stored and make a double click on it (remove the .txt extension first so that is shows .wpa as extension). It opens the required graphs for normal cpu usage and DPC usage. Load the symbols and expand the stack. This looks similar to the old UI.

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.

yeah. The important things are the 2 lines thumbcache.dll!CThumbnailProviderWrapper::GetThumbnail and shell32.dll!CPropertyThumbnailHandler::_GetThumbnailInternal. So the issues comes from generating thumbnails. Turn this off in the Explorer options and let Windows always show only the file icons

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.

there is no other workaround.
