When i bought my PC back in Junuary 2017, instantly i installed WLM 2012 the last remaining messenger, MSNP 15 had already been gone back in 2015, so Messenger Reviver 2 by @TReKiE
So the point is that after the msp21 totally gone in May 2017 , @tristanleboss posted a php file in GitHub which contains the login code in order to login on WLM 2009 2011 and 2012 and only that.without anything else.it was that time that @valtron and the others developers were hyped and talking about the future of the new then escargot. my dear friend @TReKiE helped me to setup a simple php server. and i was enable still today to login only that on my wlm 2012 installation which is back from the gold original times.
unfortunaly its not possible to make this in a new installation because the original contacts server is gone and you messenger promts an error. i guess my windows live cache is that allows me to still login.!
so thats guys.i just wanted to share this with you. cya
ps. i have the php file to send to whoever wants it.
