Something change in the last windows XP update

[francoisbrochu@yahoo.com]

as part of my logonscript I like to change some of the setting for
user so I use a batch file like this test.bat:

if NOT "%USERNAME%" == "Administrator" (
set windozPref=hello
echo %windozPref% world
)


1- run test.bat
you expect "hello world" to be echoed, but no it echo world
2- run set
you will see windozPref=hello
3- run test.bat
one more time it will echo "hello world"
4- run set windozPref=
set will reveal it's unset
5- for fun add this line to test.bat "set windozPref=foo" before the
IF statment
test.bat now look like this

set windozPref=foo
if NOT "%USERNAME%" == "Administrator" (
set windozPref=hello
echo %windozPref% world
)


6- run test.bat
it will echo "foo world"
7- run it again it still echo "foo world"
run set, look "windozPref=hello"

I really don't know why this behavoiur change in the last month, it
work just fine last month
