can you, as a lawyer for Microsoft, make a guarantee to the business that if allowed, a software developer at Microsoft who works on the Windows source code will not ever reproduce a method they saw in a GPL codebase in the code they write for their job? You can not. So what do you do to prepare for a lawsuit which alleges that you've copied GPL code into the Windows codebase? You have technical and legal barriers in place so that those developers can't see GPL code where you can control that, and make them promise that they won't do anything to compromise the license of the Windows code that they work on. Technical and legal (read: contractual) measures to prevent this are the defense that one needs to have in order to defend against a case like this, in court. So, because you, as a Microsoft attorney, can't guarantee that GPL code won't be reproduced verbatim in any quantity in the Windows codebase, you do what you can to dissuade your developers from looking at GPL code. please think for 2 seconds on your own and I won't have to ELI5.
