As far as I know the ReactOS team does not disassemble Windows.
"Is ReactOS legal?
Yes. ReactOS is fully legal.
Developers (devs) have not looked at Microsoft Windows™ source code. They have used the public documentation of Microsoft Windows OSes. They have made several tests to understand how Microsoft Windows works. In fact, ReactOS does the same things that Windows does but it does it differently as we don't have the same source code and it is all programmed by different developers. All code in ReactOS is released under the GNU GPL (General Public License).
Is ReactOS based on Microsoft Windows™ original source code?
No! ReactOS consists only of clean-room engineered GNU GPL (General Public License) and GPL compatible licensed source code. "
