修改注册表

1. Click Start, point to Run, type gpedit.msc, and then click OK to start the Group Policy Editor.
2. Open Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Accounts: Limit local account use of blank passwords to console logon only.
3. Double-click Limit local account use of blank passwords to consol logon only.
4. Click Disabled, and then click OK.
5. Quit Group Policy Editor.

NOTE: By default, this policy is on (enabled).

Under the cover, in Registry, this is controlled by

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
"LimitBlankPasswordUse"=dword:00000000
Code language: JavaScript (javascript)

Therefore, alternatively, this can be achieved by directly setting LimitBlankPasswordUse to 0. Setting it to 1 will restore the default behavior.
