Just be careful and make a back up copy before you start to tinker
If MSFS crashes or bugs out, you can get to them without having MSFS running.
Learning by trying is the best teacher!
*If msfs is not running stable for you now, maybe wait until it gets sorted out, then tinker…
Fortunately for me, MSFS has been working perfectly, with the exception of the known bugs. I’m very please with where we are at now. I go back to FS2004.
