    That was obviously run in Safe Mode - the 0x8007043c error code makes that plain.

    Can you still not get into Normal Mode?

    Did you manage to change that registry value OK? Does Device manager show the SPLDR driver as flagged, still?

    I followed what you instructed me to do. And the SPLDR is still flagged.

    OK - let's check the registry entry again, and see what it has to tell us now....

    Please run the following commands, and post the results.

    REG QUERY HKLM\SYSTEM\CurrentControlSet\services\spldr /S
    REG QUERY HKLM\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_SPLDR /S

    That looks normal apart from the INITSTARTFAILED entry - which should have cleared itself.

    Please run the following command and post the results

    SC QUERYEX SPLDR

    Please also open Event Viewer
    In the left pane, navigate to the Windows Logs
    right-click on Applications and select 'Save all events as...' save as Apps.evtx
    repeat for the System logs - save as Sys.evtx
    Compress both files, and attach to your reply.

    The first error after the reboot relates to the Computer Browser service, which fails to start because of a dependency failure in the Server service.
    Just before that, there's a flag that three boot services/drivers failed to start..
    discache
    spldr
    Wanarpv6

    so lets see if we can track it back that far...

    open an Elevated Command Prompt, and run the following commands

    SC QUERYEX BROWSER
    SC QUERYEX LANMANSERVER
    SC QUERYEX DISCACHE
    SC QUERYEX WANARPV6
    REG QUERY HKLM\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_DISCACHE /S
    REG QUERY HKLM\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_WANARPV6 /S

    Post the results, and I'll look at them tomorrow - time for bed :)

    Both the LANMAN services failed to start due to dependency issues...
    Let's run through them....
    Run the following commands, and post the results


    SC QUERYEX MUP
    SC QUERYEX SRVNET
    SC QUERYEX SRV
    SC QUERYEX SAMSS
    SC QUERYEX NSI
    SC QUERYEX BOWSER
    SC QUERYEX MRXSMB10
