Microsoft account issues safe mode

Dear Sioned Edwards!

Welcome to the Microsoft Community!

Don't worry, I will help you solve the problem together.

I read the post you posted carefully. I understand that your computer crashed, and then you chose to force shut down, then entered safe mode, and then your computer prompted that there was some problem with your PIN, and you may need an additional application to open the option (this is because most functions are not available in safe mode, so the Windows Hello component driver may not work properly.).

You then chose to restore to a restore point, but then it reminded you that your Microsoft account email password was incorrect, and then you tried to change the account password, but it still failed. In this case, your problem may be that the restoration to the restore point caused some changes in security information, so you cannot log in normally.

You can try to use a wired network connection and wait for several hours for the security information to be synchronized. Another option is to use the mobile phone USB network sharing to help with the synchronization of security information (according to some user feedback, this may indeed be helpful, but it may not be applicable to your problem).

If the above synchronization security information cannot allow you to enter the system desktop normally. The only solution now is to refer to the solution shared by community users: activate the built-in administrator on Windows 10, open the local built-in administrator account without logging in, and then try to reset the password of the account that cannot enter the desktop normally. For the originality of the solution, I sent the following link:

Activate the built-in administrator on Windows 10 without signing in - Microsoft Community

After entering the built-in administrator user account, you can press the Windows + R keys on the keyboard on the administrator account desktop, enter "netplwiz" in the run window, then view the status of all accounts, select your original account, and then check if there is a "Reset Password" option.

If so, click "Reset Password" to see if you can log in to the original account normally.

If the option is grayed out (cannot be selected), try to access the folder of the original account, export and back up all files, and then delete the account. If you are not sure if any files are not saved, make sure you have a full back up before deleting the original account.

It is recommended that you create another administrator user profile after using this administrator user account, and then use the new administrator user profile. This prevents the user profile from being damaged, causing the account to be unable to log in normally, so no user account can be used normally and cannot be repaired.

After logging in to the newly created administrator user profile, you can choose to turn off the built-in administrator account. Search for "CMD" in the desktop search box and select Run as administrator. Then we can enter the following command to turn off the Windows built-in administrator account:

net user administrator /active:no

(You need to provide your Microsoft account password in Windows in the command line options in the above schemes. Microsoft has made restrictions in recent updates. You may encounter incorrect verification passwords here)

If you have tried all the above options, the only option left is to reinstall the operating system. At this point, follow my steps below to reinstall the system and restore your computer for use.

It is recommended to remove the hard drive, put it in an external hard drive box, and connect it to another computer to back up the data. After that, proceed with the new installation of the system.

Disclaimer: This method will delete all your files and programs, so be sure to back them up first.

Before proceeding, please check the following:

To download and create Windows 10 installation media, use a blank USB drive with at least 8 GB of space and a working PC.
