To put it in a nutshell: Problematic licenses include any form of non-Open-Source licenses or licenses prohibiting commercial usage.
|Extra restriction to the GPL that prevents commercial usage|
|/wallpapers/Angelus*||Apparently released under CC-BY-NC preventing commercial usage (needs verification)|
|Fonts used as test data under proprietary license that prevents commercial usage|
|Under Windows NT4 DDK sample code license||Some can be replaced by similar code under Ms-PL Open-Source license from https://github.com/Microsoft/Windows-driver-samples/tree/master/storage/class|
|h]||Needs to be referenced / indexed that these files exist here||TODO|
