裝置加密將適用於安裝Windows 11 24H2的Home、Pro版用戶,而以Windows Update升級的用戶不會自動啟動BitLocker加密。另外,使用本機帳號登入者也不會自動啟動加密。

這消息已經流傳好一陣子。5月間德國媒體Deskmodder首先報導,微軟已在5月初證實此事。

此事引發用戶反彈聲浪。原因之一是,一旦用戶遺失加密金鑰,則未來將再也無法存取自己的檔案。二來,如同Tom's Hardware報導,BitLocker加密將明顯降低機器效能,根據媒體測試,啟動BitLocker的機器固態硬碟效能最高減速45%。而且由於在BitLocker加解密過程會牽涉CPU,系統效能也將受影響。

所幸即使你的電腦是即將預設啟動的機器,也可以自行關閉BitLocker。Tom's Hardware提供二種方法。一是利用Rufus USB服務製作開機ISO,可預先關閉24H2的硬碟加密。另一方法則是利用Windows安裝精靈;以Shift+F10指令開啟登錄檔(Registry),再將BitLocker的「PreventDeviceEncryption」值改成1即可。
