I want to open the built-in task manager with Process Explorer's Replace Task Manager option checked. I've tried: Running taskmgr.exe from the run dialog. PE was opened instead. Creating a copy of taskmgr.exe in the same folder. Then run it. The built-in task manager was opened, but not working properly(its window was blank). Creating a symbolic link (using mklink) of taskmgr.exe in the same folder. Then run it. PE was opened instead. Is there any other method I can try? Thanks.
