We have been using Informix on Windows since the late 90's.
It has definitely got better with time and the installer has improved no end.
However, being Windows, most monthly 'windows updates' require a server reboot! - not the best scheme.
Also, at times when moving to later versions we find problems that make you wonder how much real world testing was undertaken on windows.
We only use it very basically, no replication currently for HA or similar. We tried to use the timeseries datablade for a while but had no end of issues so abandoned it in the end. So like Art said it probably best to stick with what you have and know.
