That post way over-explains and complicates the process. Moving FSX to another drive is very simple. Just move your FSX folder over to your preferred location on the new drive. After that, you can now create a junction. With this, Windows will see FSX as still being on your current drive, but forward it to the location on the new drive without breaking any addons. To create a junction, open an elevated command prompt (right click, Run as Administrator) and issue the following command: mklink /j <directory where FSX used to be> <directory where FSX is now>
 
Example demonstrating moving your FSX from Program Files on your C drive to a secondary drive designated K: mklink /j "C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X" G:\Games\FSX
 
As far as cloning Windows, I believe this is actually possible. I know there is a tool that can do this via a CD, but I cannot think of the name at the moment.

This can only be changed on a global basis (it affects all aircraft).
 
You will need to edit Cameras.cfg. There are two and they are located in different places, but I cannot remember which one FSX actually uses. They are in the FSX root folder, as well as %appdata%\Microsoft\FSX\. I believe it's the one in AppData. If not, try the one in the main FSX folder.
 
Open it, scroll down to CameraDefinition.002, and change MomentumEffect = Yes to MomentumEffect = No. I'm fairly certain this is the setting you're after.
 
EDIT: Just checked and it is indeed the Cameras.cfg in AppData. Changing MomentumEffect to No does indeed remove the camera motion and leaves it in the place that you left it.

Announced on their website as well, plus mentioned in these threads:

Very likely a UIAutomationcore.dll crash. Do a quick search of this forum category or even a google search and you should find an answer pretty quick. I'd find it for you, but I don't have the time at the moment. To put it simply, you need the UIAutomationcore.dll from Windows Vista in your main FSX folder.
