you can use the gpg command line tool for this - I would advise installing the gpg4win package (to get the key management tools) from http://www.gpg4win.org/ then using the following syntax:
gpg --batch --passphrase-fd 0 --decrypt test-target.txt.gpg --output test-target.txt < pass.txt
where pass.txt is a textfile containing the passphrase and the two arguments can be replaced with session variables; it is trivial to write a vbscript wrapper which will iterate though all files in a subdir, take the filename, then strip off the final .pgp to give the target filename to pass to the command line tool.

What product of PGP are you using? Desktop home, universal server etc...
PGP offers a cli product, but there is no mention I can find that you can do this without the added product.. but you might be able to use another product, like GPG to do it
http://www.pgp.com/product
Here is the windows version of GPG: http://www.gnupg.org/(en)/
http://www.gnupg.org/docum
install the software, go to a cmd prompt, change to the installed directory (cd c:\program files\gnu\gnupg )type
gpg -d filename.pgp
You may have to import your keys from PGP first tyoe gpg.exe --help for all the options
