Answer / girish tryambake
The major difference between the two is that GetMessage()
doesn't return until it finds a message to retrieve from the
Application Queue, this allows us to free up precious CPU
usage for other programs to use. PeekMessage() returns
immediately weather there are any messages or not, this
allows us to utilize the time between messages, for example
to render a 3D scene.

Answer / sandeep
GetMessage essentially waits for any message to be placed in
the queue
before it returns. On other hadn, PeekMessage function does
not wait.
That means GetMessage can block until the message appears in
the queue.
