I use uWamp for a long time on Windows Vista, 7 and 10 but it don't work on my new computer (Dell XPS with core i7 10th gen) : Apache don't Go.
The port 80 is used by "system" so y change it many times without effect.
I install Wamp and I have no problem when I use port 81.
What happens with uWamp?
