Yay! Someone who has same problem as me. Thought I was going crazy!
But wait! I have an answer that *may* work for you.... After I got sick and tired of constantly resetting folder views, re-installing, I found out where that info is stored in the registry. After a fresh install, I exported them and whenever things get fubared, I just double click a few .reg files, set the folder views back the way I like them, and I'm good to go for another couple months.
Hope it works for you, here's the text of the registry entries...

Basic gist of it is to copy and paste each of the above(not including the bold filename) into notepad and save with the filename indicated in bold. Then, double-click to add to your registry.
And..One note of caution, I am using XP Pro and can not guarantee that this won't totally fubar your system. I can tell you this works like a charm for me everytime but *use at your own risk*
