List of them:
%ALLUSERSPROFILE% --------------C:\ProgramData
%APPDATA% ----------------------------C:\Users\{username}\AppData\Roaming
%COMMONPROGRAMFILES% -----C:\Program Files\Common Files
%COMMONPROGRAMFILES(x86)% --- C:\Program Files (x86)\Common Files

%HOMEDRIVE% ----------------------------C:
%HOMEPATH% -----------------------------C:\Users\{username}
%LOCALAPPDATA% ------------------------C:\Users\{username}\AppData\Local
%PROGRAMDATA% ------------------------C:\ProgramData
%PROGRAMFILES% ------------------------C:\Program Files
%PROGRAMFILES(X86)% -----------------C:\Program Files (x86) (only in 64-bit version)
%PUBLIC% ------------------------------------C:\Users\Public
%SystemDrive% -----------------------------C:
%SystemRoot% C:\Windows
%TEMP% and %TMP% C:\Users\{username}\AppData\Local\Temp
%USERPROFILE% C:\Users\{username}
%WINDIR% C:\Windows

%APPDATA% is differnt.

In windows 7, it shows "C:\Users\UserName\AppData\Roaming"
While the common application data folder should be "c:\ProgramData"

Please check link in question for details about common app data folder.

%ProgramData% does not work on WinXP

I tried Set but the list doesn't include "c:\Documents and Settings\All Users\Application Data".

Does the command list all available shortcuts?

Try
%CSIDL_COMMON_APPDATA%

Haven't tried it in WinXP yet but it doesn't work on Win7

In windows 7 : %APPDATA%
In winXP : %CSIDL_COMMON_APPDATA%

%AppData% is the current user's application data, not the common one.

CSIDL_COMMON_APPDATA is not an environment variable under Windows 7 or XP.  It's a special folder location used within the shell by developers.

Thanks
