- Southern Netherlands remains Habsburg according to the Third Treaty of Versailles, for her contribution France may receive some territory around Hainaut and Ypres, but it would make too much sense for Louis XV so it's not a given.
- Prussia is absolutely destroyed, Frederick II probably commits suicide as Berlin is taken. Austria gains Silesia and Prussian Guelders, Saxony gains Magdeburg, Cottbus and maybe some slice of Silesia (to border Poland), Russia gives Prussia proper to Poland to annex Courland and Sweden annex most, if not all, of Pomerania. No idea about the Rhenish territories. At worst Brandenburg also losts the electorate.
- Elizabeth dies in the earlier 1760s anyways (she was very sick the entire war), Peter III may have a firmer reign this time, if his OTL policies remains he would flip to Britain's camp. This ensures the Austro-French alliance, albeit barely.
- France occupies Hanover and tries to use it as a bargain piece against Britain, however George III is the king and he care little to nothing about his German holding, so any success is this endeavor is uncertain. France probably lost Louisiana to Spain regardless of outcome.
- Poland survives... unless Russia decides to dinner some bigos.
EDIT: - If George decides that Hanover is more important than supremacy in North America the ARW is butterflied away.
