Acrobat. I'm not sure if its free anymore. If you are using a free one you find in google, it will more than likely stamp the PDF (Generated using .......)
If you cannot download anything then select Control Panel/Printers and Faxes, there may be an Adobe PDF Converter already listed there.
Well if you are being asked to create a pdf then the software has to be available to you - as mentioned above contact your IT dept.

If you have Adobe Standard installed all you need to do is right click on the file and choose convert to PDF.
