I worked on Windows back in 2014, probably the most surprising thing joining there out of college was looking through the bug database. Every issue that gets complained about online -- and many more -- are in there, and have been for a long time, marked WONTFIX due to a potential compatibility break, lack of priority, or some other policy reason.<p>I don't know if anyone even owned Notepad or any other older inbox apps like the command prompt, but the issues were pretty well understood and WONTFIXed. Single undo, unicode support, unix LF support, etc, etc.<p>For Notepad a frustrated engineer had produced a change-set to fix all of them, and it had sat there attached to the bug for some time. It would surface on internal mail threads from time to time as a joke or a bitter reflection on bureaucracy, and if I recall a VP once chimed in to say they had looked at it, and sadly none of it could be committed due to backwards compatibility issues.<p>Of course the compat issues were real (you could view reports on which obscure apps hooked into this or that internal code of cmd.exe or Notepad and would break), but I always though they served as a nice justification for whichever investments were being made at the time: certainly not Notepad.<p>It's nice to see the wind change on that, even if it took a decade or two.
