    Rich,

    Is the fault apparent during Safe mode as well? - I'm not at all confident that this will yield any useful data in this case.
    Have you run SFC?
    Have you run a Repair install?

    How to disable Fast Startup?


    Bree said:
    If Fast Startup is enabled (which it is by default) a shut down from Start is not as 'full' as you might think. Starting up after a hybrid shut down is a form of resuming from hibernation.
    A Restart is always a full start up from cold. There are a number of other ways to shut down fully, such as Option Eight here...
    Shut Down Computer in Windows 10
    Thanks Bree, for that link. I've been using Shift - Shut Down since I learned about it just yesterday. I was wondering about ways to shut down from the command line. Didn't know about shutdown.exe until I read Option Eight.

    Now that I have your attention: I wanted to disable Fast Startup but my control-panel option is permanently checked and greyed out so I can't un-check it even though I am logged in as Administrator. See attached screen shot. Any suggestions?

    That is normal @Rich Pasco. You need to click the line 'Change settings that are currently unavailable' before you can change any of those greyed-out settings.

    Duh, who'd've thunk that? Thanks! So does this setting affect only shutting down via hitting the power button, or does it disable Fast Startup for all methods of shut down, e.g. start menu power icon?

    It disables Fast Startup for all methods of shutting down.

    Thanks again. That is definitely what I want, so will un-check it on all my Windows 10 machines.

    Interesting, but it doesn't address my issue, Windows mistakenly identifying my second external drive as if it were my first. And I don't really see what DriveLetterView accomplishes that I can't already do with This PC > Manage > Storage > Disk Management.

    What it may do to help is to let windows keep the same letter to every external drive which ever USB port you plug them in and so avoid confusion.

    I have never had the problem you are trying to fix. In my experience, the same drive, plugged into a different USB port, always gets the same drive letter. Again, this is irrelevant to the problem described in my original post.
