Recent win10 (1709 or older) added checks for WER_REPORT_TYPE and reject invalid values WerReportCreate always succeeded in older dll versions.
Example failures (full report with 90 failures after upgrading from win7 to win10) http://test.winehq.org/queue/errksCfJ/report
cw1 (1709): http://test.winehq.org/data/829170f3d6b875f7a6f065072cc3334a20ff805e/win10_c...
