I was using daum potplayer video player on my win xp pro pc. I have win 10 pro now. On daum's website, the OS requirements say 8/8.1, 7, vista, xp, which is below. Can I download and install this on win 10 system or is there another link that is win 10 compatible?

Also, I was using vueprint pro on my win xp pro pc. They now offer the pro version for free. The link is below. I am not using win 10. On that link, it says " If you're using Windows 10, 8, 7, Vista or 64-bit XP, you might need to turn off Data Execution Protection (DEP) for VuePrint." What is DEP and why would I need to turn it off to use this program? Is this a good viewer or is there a better freeware viewer out there?

I was always using pdf-xchange viewer on my win xp pro pc. I see that firefox and chrome have built-in pdf viewers in their browsers. I just downloaded and installed the pdf-xchange viewer. Is there any advantage to using another pdf viewer or would the built-in pdf viewers in the browsers be sufficient?
