For Windows platforms, the Environment Variable Update bean modifies the target system as described in the following table:

Windows
Level 9x NT, 2000,
& XP
Me Special User
Privileges Required
Logout
Required
Reboot
Required
"User" autoexec.bat Registry Entries Registry Entries
& autoexec.bat
None No Yes - On 9x and Me Only
"System" Yes - Administrator

On Windows NT, 2000, and XP, any process(es) that was already running at the time the environment variable was modified will not reflect the change in the environment. Only new processes created after the installation has run will reflect those changes.
