Hi,

I noticed Directory Opus uses 25% of my CPU when the application isn't running.

I've gone through most of the steps Leo listed in the "How to find components causing high CPU usage".

Unfortunately, I only have an intermediate knowledge of Windows.

As such I only made it to the following step:  
"Select the thread using all the CPU, then click the Stack button below the list."

This is what I see when I click the Stack button:  
0x0000000000000000  
ntdll.dll!NtOpenFile+0x14  
KERNELBASE.dll!FindFirstFileExW+0x1d6  
dopus.exe+0x802ee0  
dopus.exe+0x806067  
dopus.exe+0x646a96  
dopus.exe+0x646dc6  
dopus.exe+0x6476a0  
dopus.exe+0x50734d  
dopus.exe+0x5075ff

I searched my computer for the top 3 items listed (0x000... ntdll.... KERNAL...) but couldn't find them.

Any help would be appreciated.

If you [link your account](https://resource.dopus.com/link-opus) and send us [some process snapshots](https://resource.dopus.com/t/manually-generating-process-snapshots/34071) made while the CPU usage is high, we may be able to tell from there what's causing the CPU load, and whether it's something in Opus or a shell extension, antivirus or similar.
