W2K here. But I don't see any difference between both procedures, apart from the fact that I was translating from the Polish version, so not a "System properties" but "System" in the control panel. Looks like it was the restart that did the trick. But...
I don't think Windows XP actually load autoexec.bat at start-up. Even config.sys is a blank file. These are legacy files from Windows98.
Never said you have to use autoexec.bat these days.
I wonder why do they need restart for. Are these variables set ONLY on system start? That's riduculous. Perhaps it will be enough to restart some services that have earlier acquired PATH info from the system variables. That's ridiculous too.
Wouldn't it be more convenient to restart the computer, compared to restarting individual component services? If you look at "Control Panel -> Administrative Tools -> Services", you will realise you have many components to restart. There are some services which you cannot close, which will result in the shutdown of the computer.
I don't think so. Why do I have to restart whole system when all I need is to reconfigure some small part of it? For me that's faulty desing.
I am not sure and Junior is not here so I can't ask him, but AFAIR under *nix systems you can restart any (or almost any) service individually. I am more then sure that I can reconfigure ethernet on our Linux server without restarting the system and without loosing WiFi connection - so the server will be all the time connected to the outside world, just for a moment it will be cut off the local network. If it can be done there, it can be done under other OSes as well.
Sure, there are some dependencies which can make it sometimes impossible, but Apache is a rellatively high level service, like FTP or gopher. I don't see any reason why do I have to shut them all down (restarting OS) to reconfigure only one of them. Could you imagine restarting chemicalforums web server each time you need to tweak the parameters?
Hah, IIRC you have bought a Macbook or something? Which system does it have? One of these based on BSD? Check out how many things can be reconfigured without restarting OS.
