    I am not an expert, I am Lecturer in Government College teaching mathematics .

    I knew Tamil language.

    Update means a small compressed single file which contains lots of important files which includes fixes or solves certain hardware drivers problems .

    Update file comes in the format of .CAB or . MSU

    In simple way update file is nothing but a small single tablet which includes combinations of different chemical substances, Taking tablet gives good health and relief. In same way in all windows operating system gives small problems when users test new devices ,in few cases new devices won't work , so in this case microsoft windows technical team members creates new updates and pushes to windows 10 os through windows update.

    Some times new features are added via windows update file.

    I would recommend users should always install new updates when releases to public.

    While trying to install this update, my computer now says Required file missing or contains errors.

    File: \WINDOWS\system32\winload.efi

    Error code: 0xc000000f

    It will not let me uninstall the update.

    I cannot lose what is on my laptop by resetting my computer to factory settings.

    KB009543 appears to have broken storage spaces - configured as redundant drive after the update the drive appears to the OS as raw unformatted. Uninstalling the update restored the drive. This is disappointing as I had the drive configured as redundant/two-way mirror because it holds critical data.
