Ok, so this one isnt quite a repair tool. However, I’m sure clients have or will ask for the ability to create or read PDF’s.
PDFCreator is a free utility to create PDF files that installs itself as a printer. When your clients want to turn something like a word document into a PDF, all they have to do is choose print and choose the PDFCreator printer. PDFCreator will ask you where you want to save the PDF and then go ahead and create it. By using this printer method, it allows you create PDF’s from almost any program.

FoxIt PDF Reader is a very light-weight PDF reader with comparable features to Adobe Acrobat Reader, but without the bloat. Adobe Reader is a 27.5mb download just to read PDFs, FoxIt does it with just a 1.67mb download. Loads much quicker too.
