MsSense.exe high CPU and memory usage usually occurs when Windows Defender is scanning your PC and can get stuck during that process.

However, you should know that during scan, it’s normal for the process to take up to 50% of CPU. Another way to mitigate the problem is to change the scanning schedule so that it performs the scan when the endpoint is not active.

3. Fix Defender for Endpoint (MsSense.exe) locking files

For some of our readers every time the application downloads a file from the server, mssense.exe creates an RWD lock on the file for a short period of time, but enough for the app to return an error when accessing the file. By adding a folder exclusion in Microsoft Defender as shown above, you will avoid this issue.
