1、常用激活命令，不直接改注册表文件
cmd
net user Administrator /active:yes
2、A、启用 Administrator 账户（.reg）
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SAM\SAM\Domains\Account\Users\000001F4]
"F"=hex:02,00,01,00,00,00,00,00,00,00,00,00,00,00,00,00,\
00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\
00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\
00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00
上面注册作用：把 RID 500（Administrator）从禁用改为启用。
2、B、让 Administrator 在登录界面显示（.reg）
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList]
"Administrator"=dword:00000001
2、C、导入后必须执行的命令（管理员 CMD）
net user Administrator 123456
net user Administrator /active:yes
把密码设为 123456（你可以自己改）
确保账户真正激活
然后重启电脑，登录界面就会出现 Administrator 账户。
3、如果要返项操作
禁用.reg
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SAM\SAM\Domains\Account\Users\000001F4]
"F"=hex:02,00,01,00,02,00,00,00,00,00,00,00,00,00,00,00,\
00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\
00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\
00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00
隐藏.reg
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList]
"Administrator"=dword:00000000
CMD 再执行：
net user Administrator /active:no
