And what does all of this proof? That Microsoft puts so much intelligence in its operating system that its is impossible to comprehend for normal persons? Or that they want an absolutely closed shop, so no one can build third party utilities for these matters? Or that they are incapable of properly documenting these things?
The fact that with Microsoft tools you can not even copy a system disk to a new bootable system disk of the same or larger or smaller capacity is downright laughable. Third party utilities can do that, and now you write that you never know if the result is actually a good one. Well, shame on Microsoft that third parties have to write such utilities.
Windows-NT and its successors is partly based on plain theft. Microsoft stole the memory management from VMS (OpenVMS today), that is well documented. Perhaps they could have stolen the backup utility of VMS as well, that might have learned them how to copy and at the same time defragment a system disk.
