It seems you read but ... Win10 is a 64bit system. deutch1976 confirmedbflasher works, BUT did you also put the libusb libraries in place? Flashing N900 is always eMMC first, then combined (without starting up in between). In special cases when system does not boot or flash does not work yuo have to do combined - eMMC - combined. For the combined image just take the latest 2001-38, once.
