Win10 cannot access Shared resources due to Microsoft Account Login

Baidu has found a lot of solutions to solve the problem. The simplest way (probably a bug) is ):

After testing, Win10 was logged on with a Microsoft account. When a LAN was shared, when the user name was entered, a messy domain name was added to the front to access it:

For example, the user name: ba \ administrator password: ********* the ba I lost at will be able to enter, without adding a \, there will be a problem of access failure.
