Set Permanent System variable through bat file

This is a follow-up to Set Permanent Environmental Variable in Windows XP.

I want to change System variables in XP through running a bat file. But when I run it I get the error "Too many command-line parameters"

This is the code:

set KEY="HKLM\SYSTEM\CurrentControlSet\Control\Sessions Manager\Environment"
set PATHxx=%Path%
reg add %KEY% /v Pathx /t REG_EXPAND_SZ 5 /d %PATHxx%

How can I fix this?

Should the 5 be in there?

You've probably got spaces in your path

Try this:

set KEY="HKLM\SYSTEM\CurrentControlSet\Control\Sessions Manager\Environment"
set PATHxx=%Path%
reg add %KEY% /v Pathx /t REG_EXPAND_SZ /d "%PATHxx%"

You also might want to include:
