The countries occupied by the Germans will either be absorbed/annexed as territories by the Reich (Czechia, Poland, Baltics, any bits of Russia occupied) or be run by fascist governments vetted by Germany and economically tied to the German economy with German bases in these countries and their militaries German equipped and under German control (like the WP). Hungary, Romania, and Bulgaria will take whatever spoils they get and be happy they remain relatively independent, treaties with the Germans but probably technically independent military forces although strong economic ties. Italy is a big question mark, however with no invasion of mainland Italy, even with Libya, Sardinia, and Sicily gone, Italy has gains in at least parts of Yugoslavia, Greece and the Aegean so I expect they will still be independent but strongly tied to Germany You may see a sort of independent Croatia, like Slovakia - small and totally dependent on Germany. Finland and Sweden will probably not be invaded by Germany, a large expense for little gain, and Finland was a co-belligerent against Russia. Keeping Finland and Sweden "neutral", as well as Switzerland, gives the Germans access to the west in ways not possible through the countries now fascist.
If the technocrats are given more power over the German economy, they can last a long time. You won't see Norway (or any other country) rebelling, they Nazi response would be without limits - chemicals, even nukes. The only folks who will actively resist are those who already consider themselves dead - those scheduled for death through labor, death camps/extermination, or life as slaves. For most of the folks in Western Europe in the occupied now fascist countries if you keep your head down, stay non-political, and are not a former communist or hiding any Jewish ancestry, you can live your life in relative peace and comfort. OTL "ordinary" folks really did not get the door broken down by the Gestapo in the middle of the night. Furthermore, once the war is ended, Nazi propaganda/education will be molding the minds of the population especially the youth.
