As the topic title suggests, "Windows XP, hates .PSD Thumbnails!!!!"
for some reason my windows XP, has now decided, not to show thumbnails of my .PSD files, while all jpeg and tiff files appear as thumbnails. i am sure, that its not my fault, because i remember NOT chainging any settings in my PS CS2, and my copy of windows XP.
I have no clue, whats going on....

What is surprising is that you had thumbs in the frst place, as PSDs have not shown as thumbs in Windows since v7. There is a workaround to get them to work by installing PS7 and deleting it again leaving a bit behind. I forget now as I use Bridge and the fantastic Directory Opus [which is Windows Explorer as PS is to a $20 photo programme]. Directory Opus shows PS thumbies fine, but like most progs only if saved appropriately.
Just had a look at my tweaking XP notes and this is what I wrote before when I worked out how to fix it. Someone's else's info in there too I think.
The File Browser cache is only for the File Browser. On my machine I have
a Photoshop 7 and Photoshop CS folder under C:\Documents and Settings\<user
name>\Application Data\Adobe\FileBrowser. I don't need the Photoshop 7
folder anymore so I can delete it; it's still there because I kept my shared
folders during the uninstall of Photoshop 7. The CS File Browser takes a
while to generate but once it's done the the preview is very fast and very
good.
2. Thumbnail generation in Explorer dialogs is handled by OS shell
extensions, in the case of PSD, a file called psicon.dll. This was
intentionally left out of Photoshop CS because it was causing a lot of
problems with very slow or locked Explorer displays, and the "can't save
this file because it is already open" problem. If JPG's or TIF's were
associated with Photoshop during a custom install of Photoshop 7 this
psicon.dll would manifest itself on these files in the form of a tab in
properties dialog called "Photoshop Image", and "Generate Thumbnails" was
turned on by default. It's my personal belief that this wasn't meant to be
for JPG's and TIF's, just PSD's, because the Windows OS already has shell
extensions for JPG's and TIF's. Unchecking "Generate Thumbnails" usually
cleared up the problems. I never had a problem using PSD's with "Generate
Thumbnails" checked but others did, although I did have the "can't save this
file because it is already open" with Illustrator files until I turned off
"Generate Thumbnails" in the Illustrator file properties dialog. What's
confusing about the terminology is "Generate Thumbnails" controlled not the
large thumbnail image in "Thumbnails" view but the small thumbnail image in
"Icons" or "Tiles" view (Win XP terminology, it's called "Large Icons" in
Win2000), so even though I had "Generate Thumbnails" turned off I could
still see the large thumbnail images in "Thumbnails" view.
3. In Preferences > File Handling, "Image Previews" adds a small (4-6k)
embedded preview in the file for displaying in "Thumbnails" view that is
unnecessary for TIF or JPG thumbnails to be read by the OS but required for
PSD thumbnails. This does not affect the File Browser previews.
4. The readme for Photoshop CS states: "Photoshop CS no longer provides
thumbnail icons of .psd files through operating system folder windows.
Please use the File Browser to view your .psd thumbnail files."
I still had the Explorer image previews I wanted on PSD files created in CS,
so I knew that CS used the PS7 shell extension, this was verified by
checking the registry. In order to keep this functionality after
uninstalling PS7, I clicked "No to all" when asked to delete the shared
files during the PS7 uninstall. I have the same previews that I had in PS7
and they behave the same way as they did in PS7.
