If that was your point . . it was not expressed well . . or was lost in the thread.
First . . That IS a problem for people those that are not very computer literate. Since this is the default with XP it will confuse people that only understand browsing with the UI and do not know how to change the explorer settings (most power users change this default just after install or set it up with the OEM “scripts”).

But, MS can not change a past default easily and XP is going EOLed so there is little need to “fix” this. So while this may be a gaf it will be a short lived one. In the computer software world this is rather minor. . . but possibly annoying.
IF your explorer is crashing your system has problems. .BIG problems that are not relevant in this discussion, and if you take no attempt to fix it . . well I will not comment on that.
"Uninformed?" well, if you do not know how to unhide directories, fix your failing system, or know how to change the default directories . .you are a windows Novice . .and being such not qualified to make such harsh statements on an OS you dot know more about.
Back up my statements

A applaud your request of proof, it shows critical thinking .. . but have to laugh at your brashness . . you could have kept from looking a bit foolish by doing the simplest internet search . .
There are many ways of doing this . .in fact you can force the OS installer to make the changes default.
The “network” way of handling this is
“Roaming User Profile” I know you are a novice if you do not know what this means. There are a host of ways to set this up and I WILL NOT give a tutorial . . Read a book
“Folder Redirection” using IntelliMirror . . can be combined with roaming.
Here are a few reg entries . .there are more
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\DocFolderPaths
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders

Also allot of “tweek” programs help allot if you do not what to do this manually . . .
Also I tend to move the “Programs” directory. (because till the “rule” takes hold some programs keep user data in the install dir.)
This makes imaging the boot partition easy and allows a corrupted partition/drive to be replaced with out loss of data.
With Vista you have additional possiblies . .
So, Ahem . . . my statement stands
One of the reasons MS has made more strict rules on using the user dirs, is because poorly written programs and widely diverging ideas of where the data should go has made problems in the earlier OS’s. Is there implementation correct? The best way? Not known yet since few have vista and few are writing for the new specs yet . .time will tell.
I would suggest that you fix your explorer problem and make a short cut there (this may not be bad advice Yarlen for stardoc . . put a shortcut in the menu to the screenshot dir to save on tech calls)
(ps. I am working of a Sun blade 2000 running Solaris 10 . . and a genaric xeon based PC at this moment in time - so hold no OS pregidous, I have been in the computer industry for over 15 years - ug way over . . though definitely not infallible, I think I may know something about these things )
