It seems to me that I have found the solution how to back .max thumbs in windows 7 explorer.
You need to add this code in the registry. Use included .reg file or code below.
Be sure you know what you are doing and create registry checkpoint. Of course to get it work you need restart your pc after have finished adding registry keys.
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\.MAX]
[HKEY_CLASSES_ROOT\.MAX\PersistentHandler]
@="{98de59a0-d175-11cd-a7bd-00006b827d94}"

But after you have added this code your thumbnails will not be stretched at full size. At this time I have found the only way to avoid it is remove 3dsmax.exe association with .max files. That’s not a good idea but it works.
To do this you need to find and remove key named something like this:
[HKEY_USERS\S-1-5-21-1697047998-497193070-276207954-1000\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.max]
I’m looking forward to get this solution better…
