I have a laptop that displayed this error immediately after an update. I have seen this question posted before, but everyone has a slight variation from my situation. I can change to password from PIN, but the password doesn’t work. I changed my Microsoft password on another device and it still doesn’t work.

I would appreciate any help - I have important files on the desktop that I can’t access. Also, if you don’t mind please be specific. I’m in the medical field and technical jargon is foreign to me. If you say ‘download a lotus flower to your backup file and reboot in safe mode’, please direct me on how to do those actions as well (those clearly aren’t real actions, but simply there to illustrate the point).

I have an iPhone and iPad in addition to this windows based desktop.

Thanks in advance

    Hello,

    Based on the description, it seems that the login process itself failed due to corrupted system files.

    Since there is no other administrator account, there is no supported way to log into your account.

    Based on the situation, I recommend copying your personal files to external storage (like USB sticks, external hard disks, and memory cards). If you know how to use the Linux command line, you can boot up a Linux boot disk, mount the Windows partition as read-only, and copy your personal files located at (mountpoint)->Users->(user name) to the external storage. If you do not know how to use Linux, please contact your local repair shop to let them copy the files for you.

    After copying the files, you need to perform a clean reinstallation of Windows 10, which erases all the data on the hard disk, and starts you from scratch.

    To do so, please prepare a USB stick that is at least 8 GB in size (do not use the one with your backups, since it will be erased), then download and run the Windows 10 Media Creation Tool on another computer. Follow the instructions, and when selecting the media type, please select "USB stick", and then select the drive letter the USB stick is in.

    After creating the installation media, please plug it into your computer, and boot from it in UEFI mode. The exact procedure differs among motherboard manufacturers, so please refer to the user manual for details.

    Also, please check the following BIOS options, as some motherboards use RAID mode by default which needs specific storage drivers that may not be compatible with the latest version of Windows:

    • SATA controller mode: Change to AHCI mode (even if there is no SATA disk)
    • NVMe RAID mode: Turn off
    • Intel Rapid Storage Technologies/AMD StoreMI: Turn off

    Disclaimer: Microsoft provides no assurances and/or warranties, implied or otherwise, and is not responsible for the information you receive from the third-party linked sites or any support related to technology.

    If you are going to modify BIOS Settings, please back up all your personal files first to ensure you do not lose data.

    After booting, please select "Install now". Follow the instructions, and when selecting the installation type, select "Custom: Install Windows only". On the next installation screen, please delete all the partitions (including EFI, reserved, and recovery ones) in your system disk. Select the unallocated space and select "Next". The installer will partition your system disk automatically.

    Disclaimer: At this point, we have exhausted all troubleshooting and I recommend that we try to perform a clean install to get your computer back into a working condition. Please ensure that you backup any important data, including Documents, Pictures, Videos, and more.

    Thanks for your patience and understanding.

    Best Regards,

    Sorry Sheng, I’m usually tied up on all days but the weekend. The computer is my personal computer - school is a distant memory. Here is what I see on the screen - there are no other options available to me. I’ve tried every password I’ve created (including the one that currently works for the email listed) as well as the pass key that should also work

    Hello Cory Brown,

    Thanks for reaching out here in the Microsoft Answers Community.

    Error 0xC000006D means that the username or password is incorrect. Since the error usually occurs when connecting to a remote server instead of just a Microsoft account, is the computer yours, or managed by your workplace/school? If so, you need to contact the IT department of your workplace or school for further assistance regarding the policies they have put on.

    If the computer is yours, are there other administrator shown in the bottom-left that you can log in to?

    We look forward to your response.

    Best Regards,
