Is true decompilation possible?
No, of course not. Fully automated decompilation is not possible – no decompiler could exactly reproduce the original source code. Well, we hate to burst your illusions but PE Explorer does not decompile code. It disassembles code, which is the task of converting machine code into assembler, but it does not generate C or C++ code from the disassembled output. Which is a task of great difficulty.
