What is the problem? You didn't write it. Just some outputs and config, but you never mentioned what is the problem itself.
archive_mode = onarchive_command = 'copy "%p" "C:\\Program Files\\PostgreSQL\\9.3\\data\\pg_xlog\\%f"'
This archive_command looks bad.
Is c:\program files\postgresql\9.3\data\pg_xlog directory for xlog for THIS postgresql?
Is c:\program files\postgresql\9.3\data\pg_xlog directory for xlog for THIS postgresql?
If yes - why would you want to copy xlog back to its original location?
If no - while it might work, I don't think it's safe to copy xlogs directly to pg_xlog directory of slave (assuming it's slave).

Hi,
First - do not take the messages off list. Someone else might be able to help you if you'll mail to the list, I'm not always there, and others might have better ideas.

But there is no ERROR?! What error are you talking about?
This is just notice and a warning.

i changed in postgresql.conf to archive_command = 'copy "%p" "C:\Program Files\PostgreSQL\ramesh %f"' still working same error return..
What error? So far you didn't show any.
Is the archiving working? Are there files in c:\program files\postgresql\ramesh ?
If not, what does pg logs say about archiving? Any errors there?

I believe, you have to give the archive_command in windows like below, due to window's escape sequences behavior.
'copy "%p" "C:\\\\Program Files\\\\PostgreSQL\\\\<Archive Location, where postgreSQL Instance owner has the permission>\\\\%f " '

Fix the archive command so that it will actually work (files should appear in destination directory).
I have 0 knowledge about windows, but I would guess you need to use \\ and not \ in the path. Also - does the destination path exist?

Also, on windows, one can use the forward slash ‘/’ instead of the backslash in a path
Just my 2 cents.
