I want to use dynamorio to monitor the execution of svchost.exe in windows.
By When I register it in Dynamorio and restart the windows,I found that it
seemed the instrument is invalid. I know that the svchost.exe does not
import the user32.dll,by after i use a PE TOOL to add user32.dll import
entry to svchost.exe( remove file protection),the problem still exists.
What is wrong?
