Welcome to WebmasterWorld Guest from 18.104.22.168
PS I'm running Apache 2.0.54 - a little ancient - but it has been fine for the testing purposes I use it for. One of the computers I use has Vista - the others Xp.
As for Apache, if you have "Apache Monitor" installed (in the taskbar), then you can Turn Apache ON/OFF there. Otherwise use the links in the start menu Apache folder. (You can also be able to kill the httpd.exe process (ie. apache) via task manager)
If they these are automatically started when you turn on your computer, go to Start > Run > "msconfig" and disable the appropriate Service/Startup Program. You should never uninstall a program unless you want to get rid of it completely.
