Hi @George Aggrey ,
There is not much difference between IIS10 and IIS7.5 in terms of overall functions and architecture. If you look at the updates in IIS8 and IIS10, you will find that there are no compressed updates involved.
So the compression module in IIS10 still follows the description in the document. It will only compress responses whose status code is 200. This is by design of IIS. Unless you write an custom module to set compression for 201 response.
