Windows Explorer want images not icons

FOR THE RECORD I HATE BRIDGE, DON'T NEED IT DON'T WANT IT F'ING HATE IT IT DISPLAYS PICS IN SMALL THUMBS THAT YOU CANNOT SEE.  I GO BACK TO PHOTOSHOP 3 AND HAVE NEVER HAD THIS AGGRAVATION THAT STILL IS NOT SOLVED.  WHY SHOULD I HAVE TO GET A 3RD PARTY PLUG IN WHEN I PAY EVERY MONTH AND HAVE FOR YEARS.  

1. Excellent solve.  Recently at a new job, I realized a huge difference from my SOHO machine and the office machine was the office machine not displaying PSD and PDF icons.  My Soho machine has always worked for many years and I recall paying for a codec which has faithfully served me.  Not being able to spend money on this, I found your solution worked great for the PSD - but not the PDF.  Adobe says reader can show thumbs but it only works (for me) on 32 bit - and I'm forced using 'daCloud' which I absolutely hate. but I digress.   I then used a free reader tool called Foxit - and after some initial issues trying just to get their free reader, I succeeded and lo-and-behold PDF thumbnails work for me now as well.  Zero dollar sane solution. thanks!
