1. Open Process Hacker and navigate to the Processes tab
2. Click on the "CPU" column header to sort processes by CPU usage
3. Identify the process with the highest CPU percentage
4. Right-click the process and select "Properties" to view detailed information
5. Check the "Threads" tab to see which specific threads are consuming CPU
6. Review the process path and verify it's a legitimate application
7. If suspicious, you can suspend the process temporarily or terminate it if safe

Problem:

System memory is gradually being consumed, and you suspect a memory leak.

Solution:

1. Monitor the "Memory" column in Process Hacker over time
2. Look for processes with steadily increasing memory usage
3. Use the "View → System Information" to see overall memory trends
4. Check the "Memory" tab in process properties for detailed memory breakdown
5. Identify processes that show continuous growth without corresponding activity
6. Document the memory usage pattern and report to the application developer if needed

4. Check remote addresses and ports to identify suspicious connections
5. Use the filter options to focus on specific protocols or addresses
6. Right-click on connections to view detailed information or close them if necessary

Problem:

A Windows service is not starting or behaving unexpectedly.

7. Check service permissions and security context if access issues occur

Problem:

A file cannot be deleted or modified because it's locked by a process.

Solution:

1. In Process Hacker, go to the process that might be locking the file
2. Right-click the process and select "Handles"
3. In the Handles window, use the search/filter to find the file path
4. Identify all processes that have handles to the file
5. Review the handle type and access rights
6. If safe, close the specific handle or terminate the process holding the lock
7. Alternatively, use Process Hacker's "Find Handles or DLLs" feature to search system-wide
