example:
%ProgramFiles% will give you your program files folder.
in this case the same as $PROGRAMFILES
another example:
%Temp%
same as $TEMP

Just emphasising that this is a compile-time reference, not run-time, so $%TEMP% will give the path of your temporary files folder, not that of the person using your installer.

If you e.g. %COMSPEC% on run-time (to get user's command prompt path) use:

ReadEnvStr $R0 "COMSPEC"
; $R0 = e.g. C:\Windows\System32\cmd.exe
