在Windows系统中，BL锁（Boot Lock）是一种安全特性，用于防止未经授权的更改启动顺序。了解BL锁的状态对于系统安全维护非常重要。以下是如何使用cmd命令查看BL锁状态，以及一些实用的技巧。
查看BL锁状态
要查看BL锁状态，你可以使用以下命令：
”`cmd bcdedit /set testsigning on bcdedit /store %temp%\BCDTest.bcd bcdedit /store %temp%\BCDTest.bcd /set testsigning off bcdedit /import %temp%\BCDTest.bcd bcdedit /store BCD.bcd bcdedit /store
