Great, you still have the old .exe and it works fine for you. Could anyone who does not have the obvious fix that not everyone is capable of having verify they cannot use compatibility mode?
Sorry, I misread your post, I thought you said someone with the old unpatched exe. Sorry about that.
You are aware, you can just get old EXE, copy it over your patched one, then either don't run steam (so it doesn't patch, or turn off Skyrim updates in Steam, and it will work as it did before?
But this means NEVER launching steam right?
What if I do launch steam by mistake, will moving my back up of the first EXE to override the new one steam puts in it's place ....still work?
Yes, as I said above you can just put a backup in there and it will work again. As long as you have Steam off, or turn Skyrim updates in Steam off.
