TITLE: Automatically updating PDF reader for Windows
QUESTION [13 upvotes]: So, when doing LaTeX, it is absolutely necessary for ones sanity to using a preview program which updates automatically every time you compile.  Of course, any previewer designed for DVIs will do this, but as far I can tell, Adobe Acrobat not only does not automatically update, but will not let you change the PDF with it open.  
On a Mac one can get around this by using Skim, and on *nix by using xpdf, but what should one do on Windows?

REPLY [2 votes]: gsview can display pdf files, automatically updates them when the file changes, and does not lock the file so you can modify your files and compile them without closing the pdf file.
