Rather than say what the code does, say why, e.g.

// The Windows Restart Manager expects a string of command line flags only,
without the program.

or some such.

Done.

I am OK with this if cpu is OK :-)

Yeah, we may want to handle crashes, hangs, and patches...
However, the crash handling is redundant with our custom module and dialog, and
I haven't explored hangs or patches.
