If running Linux on same physical computer as Windows, can one legally use Microsoft's files?
Apparently not. The fonts would be considered a feature of the software.
Even mounting the Windows file system in your Linux partition, as opposed to copying the fonts, would violate the terms of the license. That is because the terms of the license allow the inference that the licensed copy of Windows 10 is mutually understood as the active partition at the time of using its features.
Therefore, using the fonts from elsewhere (including a different partition insofar as the license considers it a device on its own) constitutes using the feature separately.
