Every time you load an image, NTLite performs a new inventory of Components, Services, and Settings based on the image's written content.
Component removals and Services changes are permanent, after you have applied changes it's impossible to revert. The only way is to start over from a previous copy of your image. To use a computer term, Windows images are "stateful".
The only option available to update Services in an offline image to disable them, which is the same function as removal. Removals are permanent, so you cannot restore a previously disabled Service after applying the image.
