Hello,

Microsoft has added a new security mechanism to Windows 11, so the access without a password is considered unsafe by the system. 

 

You can set an administrator user with a password on the shared computer. 

 

Or try to modify the registry key of the Windows 10 computer, refer to the following: 

 

1. Press WIN+R to open the Run window, type regedit and confirm to open the registry editor 

2. Locate the following location: 

HKEY_LOCAL_MACHINE—-SYSTEM—- CurrentControlSet—-Services—-LanmanWorkstation—Parameters 

3. Right-click in Parameters and rename the new DWORD (32-bit) value to AllowInsecureGuestAuth with a value of 1 and save

Note If you modify the registry incorrectly, you can cause serious problems. Therefore, follow these steps carefully. For additional protection, back up the registry before you modify it. For more information about how to back up and restore the registry, see How to back up and restore the registry in Windows.

Best Regards
