  Hey I Had Just The Same Problem Untill I Realised A Program Was Doing It Here Is How To Fix The Problem :) The Error COM Surrogate Has stopped working whenever you browse folders containing video or media files This problem is caused because of codecs and other COM components installed by various softwares that aren't fully Vista-compatible, like some versions of DIVX or NERO If you are using DivX, you should be upgraded to the very latest version (6.5+) If you are using Nero, you can try upgrading to the latest version (7.7.5.1+) If you’ve upgraded Nero and Divx and still have the problem, you can try renaming the file C:\Program Files\Common Files\Ahead\DSFilter\NeVideo.ax to NeVideo.ax.bak. To Get To This Just Go To Run Highlight It Copy And Paste It Into Run You may also need to rename NeVideoHD.ax to NeVideoHD.bak This will break Nero Showtime, however. (thanks to dugi in the comments for this one) You can disable Thumbnail previews, which should make the problem go away, but isn't the optimal solution. The Best Thing To Do Is To Uninstall Either Nero And Or DivX It's The Safest Thing To Do :) Hope I Helped :)
