Please change your description from the no-install light-weight.... to at least include the fact that this install requires the host system to have Visual C++ installed (PHP 5+ requirement). Maybe a "System Requirements" section would cover this quite nicely and save people some hassle. Looks good once installed though.
This seems like a decent server package, and while I would love to use it, it just isn't usable in the current state it is in. #1, when you create a package like this, it is going to be used by power users. I don't know anyone who uses windows Notepad.exe to edit their configuration files. Everyone that I know that would even use this will have their own power editor to handle these tasks. Forcing them open into notepad and bypassing the "default" editor already set up is an insult to me and other power users that I know. There should be an option to configure what editor will be used or allow the system to open whatever is set as default. Real programmers/developers don't use notepad! I really like the idea of having these configuration files easily accessible, but the way it is implemented, you might as well have left it off completely. Until this is fixed, I simply can't use the software, as I won't go to the trouble of making workarounds for another person's oversight. #2, automatically checking for updates without permission from the user is unacceptable. I want to control whether any particular program is allowed access to the internet and when. Update checking should be configurable to allow either 1) daily checks, 2) weekly checks, 3) monthly checks, or no update checks at all. There should also be an option to manually check for updates, so the user can just check whenever they feel like it. People who have limited monthly bandwidth really get angry about things like this. We only use the server for development and testing, and not for putting it on the internet. Not everyone is hosting their own internet server that uses your software, so don't assume we're always connected or have unlimited bandwidth available. Respect your users if you want respect for your programs. That's as far as I got with Z-WAMP before I removed it. Can't say much about the functionality as a web server until those issues are corrected.
