I'm not familiar with the windows registry but I'll try to run a search on the words php and mysql. There are 2 PCs that I use. At work, the PC here has no PHP/Apache/MySQL/IIS. They were uninstalled and I have checked all the folders for any remaining config files that weren't deleted and removed them. At home, the PC I use has IIS6, PHP4, MySQL installed and running. I have yet to run uniserver on this PC because I'm still unable to reconfigure uniserver to run well on a PC without those software.
