If, like me, you have Windows 7 (or Vista) 64 bit installed, you may have noticed an annoying glitch – whilst the file previews are much better than they ever were in XP, they can’t quite manage PDFs. You get a funky message in fact:

PDF Preview Handler for Vista
To open this file in its own program, double-click it.

For the last 6 months, I’ve just kind of ignored this. But I finally got annoyed enough with it to try and find a solution. As with most of these things, 3 seconds on google found me the answer.

1. Go to this website.
2. Download the patch.
3. Run it.

Sorted. It will update your registry to make thumbnails and previews work, making your life at least 3% better.
