So, one more W10 Update later and now EVERY save game crashes to desktop ...

Edit.
Just fixed this problem.
First I've taken out the Oblivion.ini and started the game but this led to the same crash so I put my ini back and tried to remove the EBNBoost d3d9.dll but I could not because "Oblivion was still running" so I did a reboot of my pc and now everything was "fine" again, meaning that all my saves could be loaded but went CTD after a few minutes ingame. But at least I could use a "fresh start" at the end of the tutorial sewer from where I entered the landscape, put my avatar on the bridge there and went afk to do some shopping and when I returned after about an hour everything  was still running without any problem.
So whatever the problem with my save games, it's probably not W10, Nvidia or OSR-OR related :)
