  1. Windows not booting after update (0xc000021a)


    Hey,

    So my laptop automatically attempted updated itself to a newer version on windows overnight a few days ago, however it is no longer booting and goes to a blue screen with stop code 0xc000021a.

    I was on 1909 as the update would always fail but this time its not booting up so I am not sure what happened this time only that I woke up to a not working laptop.

    I would very rather not reinstall windows as I have spent hours perfecting settings to how I like them in every single application that I use and especially things like Cura which has taken hours and hours to do so.

    Any suggestions much appreciated, thanks
