PDF Reader is a free program to view, modify and print pdf files. It is very small, only about 4 MByte to download. You can open, view, zoom and print PDF files. You can also modify pdf files (but you can not save them in the free version). You can add, change and delete text and pictures and print it out.

If you need a commercial PDF viewer which do not offer any edit functions call PDF Editor from command line like this:
pdfedit.exe VIEWER test.pdf

or if you do not need the print command then call it like this:
pdfedit.exe VIEWER test.pdf NOFILEMENU
