    Canon i560 printer suddenly stopped working in Windows 10

    Upgraded from Win 8.1 to Win 10 several months ago, and my Canon i560 printer worked at first. Then in December it suddenly stopped working. I can see it, query the status of the ink tanks, and even clean the nozzles. But, any attempt to print to it (even
    a test page) results in an error and the message "Function Discovery Print provider dll has stopped working."

    Help?

    BSod did Verifier driver got into a loop got my dmp files!

    Related to Virtualbox driver.

    Was the BSOD before verifier a one-off? You do not need to worry if it was so. If repeated crashes,

    Uninstall Virtualbox temporarily to see if the crashes stop.

    OK, problem returned. Vbox again thinks a whole of DLLs are unsigned. Have posted in Vbox forums but help there will be slow at best. Is there any method of collectively re-registering DLLs?

    Example error line from VBoxHardening.log

    26bc.2164: supR3HardenedScreenImage/LdrLoadDll: cache hit (VINF_SUCCESS) on \Device\HarddiskVolume4\Windows\System32\shell32.dll [lacks WinVerifyTrust]
