#186434 - 2008-03-22 03:58 PM Need to delete or remove environment variables
BPalm BPalm Just in Town Registered: 2008-03-22 Posts: 1	We are currently using KiXtart to set local envrionment variables within Windows XP. I would like to remove some of those set variables without having to manually go into 200 machines. Can KiXtart remove what it has set?

This Code: Set "Test=" will remove the test environment variable. Please note that you may need to start a new instance of an app if it was running while you did the change. For example cmd.exe will not show the changes if it was running when you did the change. If you restart cmd.exe all changes are visible. The SET command will set the environment variables for the current user. The SETM command will do just the same as the SET command does but for the local system. SETM requires admin privileges for the user running the script. _________________________ Mart - Chuck Norris once sold ebay to ebay on ebay.

Glenn Barnas Glenn Barnas KiX Supporter Registered: 2003-01-28 Posts: 4403 Loc: New Jersey	First off, there are two types of environment variable - System and User. When both are set, User overrides System. System vars are defined in the HKLM hive, while User vars are in the HKCU. Once environment vars are defined, you can't tell whether they are System or User unless you consult the registry, or have personal knowledge of how they were defined. If you use Set "X=", you will unset the User var - any system var might still be defined! Again, setting these do not affect the current Kix environment, so Kix can't tell if it's changed unless you Shell another Kix script. Bottom line, if you set it with the Kix Set command, you need to use Set to remove it, and SetM to remove entries defined with SetM. If you don't know how it was defined, and want it completely removed, you'll need to define both System and User vars with empty values using Set and SetM.
