You can set the default value of the parent of $AddOnsDirectory and
$UserAddOnsDirectory via an environment variable, which works for both FE
and kernel.
MATHEMATICA_ADDONS for $AddOnsDirectory
MATHEMATICA_USERADDONS for $UserAddOnsDirectory
Mathematica will append '\Mathematica' to whatever you set, so if, for
example, you do:
MATHEMATICA_ADDONS=D:\Math\AddOnsMma
then the value of $AddOnsDirectory will be...
"D:\\Math\\AddOnsMMa\\Mathematica"
$AddOnsDirectory and $UserAddOnsDirectory in the kernel are intended to be
equivalent to something like $TopDirectory, which is to say that they're
constants derived from the system.
Incidentally, the above is true for all operating systems; it is not
Windows-specific.
