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.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.
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?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.
