To try and comprehend what today would be like if we altered an event 90 years ago is not possible. Far too many things are sparked by a random event. A genius and a dictator is born. A person tampering with a piece of equipment makes a new discovery.
It seems likely that we would have nuclear power. Even in the 1910's nuclear physics were pretty well developed. It would have taken a long time before a company/nation would have substantial financial backing to develop a process for extraction and purification. The plutonium and uranium for the first two bombs costed several billion $ to develop. Not exactly a small buisness endavour.
It also seems likely that Russia would have gone through a revolution briefly after the now non-existant WWI. Imperial Russia was not an entirely cheery place. It seems likely that the revolution would have been less violent as the country would not have been as militarized. I think the Trozkij faction would have had the best backing and I predict a Russia with elections, but still very socialistic. Most likely the US and Russia would not have been best friends.
This leads to the most important impact. Without WWI and WWII we would have a lot of unresolved buisness. 30 to 50% of the globe would still be colonies and frequent localized wars would have been fought over territory. Especially where the Congress of Europe is unable to resolve the dispute between two great powers.
The USA would still be governed by the Monroe doctine and would not interfere with world politics as such. However they will interfere GREATLY in American hemisphere foreign politics. Local wars and instabilities in South America will most likely have led the US to seize and control several South American countries for length times.
I think the remaining European monarchies will become constitutional monarchies pretty soon, following English, Swedish, Dutch, Danish and many other examples. The Hungaro-Austrian union will most likely disolve in more or less the same fashion as post-war Czeckoslovakia did. We must also assume that Austria/Hungary did not annex Croatia and Bosnia, because that was the reason why Gavrilo Principe assasinated Ferdinand.
Too many event lie inbetween. My head hurts.

EDIT:
I just noticed the wording in the title.
1) There are no winners in war. There are two losers - a big and a small one.
2) It is very unlikely that Germany would have "won". I think the best assumption would be that WWI never took place. In the event that WWI did start let's assume a quick mutual truce was signed or that all parties were able to make separate peace with the offender.
