Every time when I restart my pc the boot time is very slow and a black screen appears and then I always need to force shutdown because it doesn't launch the desktop screen . Secondly whenever I restart my computer for any updates installations the same problem happens. The power on booting time very slow as compared to windows 10 its really annoying and sometimes my fingerprint doesn't work after boot up . Microsoft should look into this serious problems as it should take less booting time than windows 10. I hope you will resolve this problem as soon as possible.
