What does this option mean, in the autounattend session? Compressed Windows, does it mean that on certain occasions it would have to uncompress to use?
 
Compact OS, single-instancing, and image optimization

I don't recommend it based on performance, but some users don't mind. Every time you read or execute a Windows file, it must be decompressed.
If your disk space is enough, there's no real point.
Thanks garlin, that's exactly what I wanted to know. From what I understand, this compresses the system when already installed, and the ESD compression would only be during the installation.
 
CompactOS writes compressed files as it installs Windows. It has nothing to do with install images using ESD compression.

ESD images can install a non-Compact OS Windows, and non-ESD images can install a CompactOS Windows. They are unrelated.

In my autounattend session it is marked false for dynamic update, but in my list of updates there is a dynamic one, in this case it would not install this one? What is the advantage of this dynamic update option marked as false?
 
Dynamic updates are optional, and pointless if you're always making up-to-date ISO's. They pause Setup, check for newer Windows updates than you have on the ISO, download them, and apply them during install. This requires a working network connection.

All it does is save the extra step of running WU right after install. But you have no control over what gets installed, because you're asking MS to update your system.
