I'm wondering how pmdg 737ngx works with windows 10 and fsx SE.  I have the pmdg 777 and it works great especially after the last update, even in and out of airports like FB ksfo hd and dreamfleet airports.  I have iFlys 737 and after I upgraded to win 10, it just sucks up memory then OOM.  It's also real jerky and brings down the frame rate to single digits.  But no one at their forum has that problem.  I've uninstalled and reinstalled to no avail.  I had the legacy pmdg 737 back years ago and now I want a 737 that will work.  My Level D works and MJC dash 8-Q400 is great, but I want to use the 737 for short trips too.

I'm intrigued that you managed to get the Level-D to work in FSX-SE and Windows 10. I had major issues with it that in the end I uninstalled it.

 

On the other hand, the PMDG 737 family work great, for me.
