Hi Richard , I am writing code to hook process but when Process run in service i can not hook anything. I think I need to create service.exe in the same explorer.exe ,and then i will hook process which is running inside service by change createServices ,startService(), change path,etc . please see attached link. https://6u7mzg.dm1.livefilestore.com/y2ptrnPlJJujhKAudu3oz8U_ObqnYpSbaZgyoDmKZCKuglr8Zg3wu_HTk7jhUSmbw-jLmNb3d1PIaZeSqWEYQ3bw0aYYeW6arUGG59c57r9f1E/processExplorer.png?psid=1[^] Thanks Thong LT
