如何在 Windows 11 和 Windows 10 上安全地停用 BitLocker

2025 年 04 月 30 日

如果您想 停用 BitLocker on Windows 11 or Windows 10, you need to turn off BitLocker protection and allow Windows to decrypt the drive. This is different from simply unlocking a drive or suspending BitLocker temporarily. Once BitLocker is fully disabled, the selected drive is no longer encrypted.

The fastest way is to open Manage BitLocker, select the encrypted drive, and click Turn off BitLocker. On Windows 11 Home, you may not see the full BitLocker Drive Encryption panel because standard BitLocker is mainly available on Windows Pro, Enterprise, and Education editions. In that case, you may need to turn off Device Encryption instead.

This guide explains how to disable BitLocker on Windows 11 and Windows 10, how to turn off Device Encryption on Windows 11 Home, how to disable BitLocker using CMD or PowerShell, how to check decryption progress, and what to do before turning BitLocker off to avoid losing access to your encrypted data.

快速回答： To disable BitLocker, search for Manage BitLocker in Windows, open the BitLocker 磁碟機加密 panel, click Turn off BitLocker next to the encrypted drive, and confirm the action. If you use Windows 11 Home, go to Settings > Privacy & security > Device encryption and turn Device Encryption off.

Before You Disable BitLocker: Important Things to Know

Before you disable BitLocker, make sure you understand what will happen.

當您 turn off BitLocker, Windows starts decrypting the selected drive. After decryption is complete, the drive is no longer protected by BitLocker. Anyone with physical access to the drive may be able to read its data more easily if they can access the computer or remove the drive.

Before you continue, check these points:

Back up important files before making encryption changes.

Save your BitLocker recovery key in a safe place.

Keep the computer plugged in during decryption.

Do not shut down the PC while BitLocker is decrypting the drive.

Make sure you are signed in with an administrator account.

Check whether you need to disable BitLocker permanently or only suspend it temporarily.

If you are disabling BitLocker because of a BIOS update, TPM change, hardware repair, or firmware update, suspending BitLocker may be safer than fully decrypting the drive.

Disable BitLocker vs Suspend BitLocker: What’s the Difference?

Many users search for “disable BitLocker” when they only need to stop BitLocker temporarily. These two options are different.

選項它的功能最適合
Suspend BitLockerTemporarily pauses BitLocker protection without decrypting the driveBIOS updates, TPM changes, firmware updates, hardware maintenance
Disable BitLocker / Turn off BitLockerFully decrypts the drive and removes BitLocker protectionSelling a PC, changing encryption strategy, removing BitLocker permanently

If you only need to update BIOS, change TPM settings, or troubleshoot a temporary boot issue, use Suspend protection instead of turning BitLocker off completely.

If you no longer want the drive encrypted, choose Turn off BitLocker and wait for the decryption process to finish.

如何在 Windows 11 上停用 BitLocker

You can disable BitLocker on Windows 11 from the Manage BitLocker panel.

  1. Sign in to Windows with an administrator account.
  2. 按下「開始」。.
  3. Type Manage BitLocker.
  4. Open Manage BitLocker from the search results.
  5. Find the drive you want to decrypt.
  6. Click Turn off BitLocker.
  7. Confirm by clicking Turn off BitLocker again.
  8. Wait while Windows decrypts the drive.

The decryption process may take some time depending on your drive size, data amount, and system performance. You can usually continue using the computer, but you should keep it powered on until decryption is complete.

If you do not see Manage BitLocker on Windows 11, you may be using Windows 11 Home or Device Encryption instead of standard BitLocker. In that case, use the Device Encryption method below.

如何在 Windows 10 上停用 BitLocker

On Windows 10, the standard way to disable BitLocker is also through the Manage BitLocker panel.

  1. Sign in with an administrator account.
  2. 開啟「開始」選單。.
  3. Search for Manage BitLocker.
  4. Open the BitLocker Drive Encryption panel.
  5. Locate the encrypted drive.
  6. Click Turn off BitLocker.
  7. 確認動作。.
  8. Wait for Windows to decrypt the drive.

You can also access this page from Control Panel:

  1. 開啟控制台。.
  2. Go to System and Security.
  3. 按一下 BitLocker 磁碟機加密。.
  4. 選擇磁碟機。.
  5. Click Turn off BitLocker.

When the process is complete, the drive status should show that BitLocker is off.

How to Turn Off Device Encryption on Windows 11 Home

Some Windows 11 Home devices do not show the full BitLocker management panel. Instead, they use Device Encryption. This is common on modern laptops that automatically encrypt the system drive after setup.

To turn off Device Encryption on Windows 11 Home:

  1. 開啟設定。.
  2. Go to Privacy & security.
  3. Click Device encryption.
  4. Turn Device Encryption off.
  5. 確認動作。.
  6. Wait for Windows to decrypt the drive.

If you do not see the Device Encryption option, your device may not support it, it may already be off, or your edition/configuration may not expose the setting in that location.

How to Disable BitLocker Using CMD

You can also disable BitLocker from Command Prompt with the manage-bde command.

  1. 開啟「開始」選單。.
  2. Type cmd.
  3. Right-click Command Prompt.
  4. Select Run as administrator.
  5. Check BitLocker status with this command:

manage-bde -status

  1. To disable BitLocker on the C: drive, run:

manage-bde -off C:

  1. Wait for decryption to complete.

If you want to turn off BitLocker on another drive, replace C: with the correct drive letter. For example:

manage-bde -off D：

To check progress, run:

manage-bde -status

Look for Conversion Status. If it shows Decryption in Progress, BitLocker is still turning off. If it shows Fully Decrypted, BitLocker has been disabled for that drive.

How to Disable BitLocker Using PowerShell

PowerShell is another way to disable BitLocker.

  1. 在「開始」按鈕上按右鍵。.
  2. Select Windows Terminal (Admin) or PowerShell (Admin).
  3. Run this command to disable BitLocker on the C: drive:

Disable-BitLocker -MountPoint “C:”

  1. To check status, run:

Get-BitLockerVolume

If you need to disable BitLocker on another drive, replace C: with the correct drive letter.

範例：

Disable-BitLocker -MountPoint “D:”

PowerShell is useful when the normal Manage BitLocker interface is missing, not opening, or difficult to use.

How to Check BitLocker Decryption Progress

After you disable BitLocker, Windows may need time to decrypt the drive. A large drive can take a long time, especially if it contains a lot of data.

You can check the progress in three ways.

Method 1: Use Manage BitLocker

Open Manage BitLocker and check the drive status. If decryption is still running, Windows will show that BitLocker is decrypting the drive.

Method 2: Use CMD

以管理員身份開啟 Command Prompt 並執行：

manage-bde -status

Check the Conversion Status field.

Method 3: Use PowerShell

Open PowerShell as administrator and run:

Get-BitLockerVolume

Check VolumeStatus and ProtectionStatus.

Do not force shut down the computer while decryption is running. If you are using a laptop, keep it connected to power.

What to Do If You Cannot Turn Off BitLocker

If you cannot disable BitLocker, try the following fixes.

First, make sure you are using an administrator account. Standard users may not have permission to turn off drive encryption.

Second, check whether the drive is locked. If the drive is locked, unlock it first with the password or recovery key, then try turning BitLocker off again.

Third, confirm whether you are using standard BitLocker or Device Encryption. Windows 11 Home users may need to turn off Device Encryption instead of using Manage BitLocker.

Fourth, use CMD or PowerShell if the Settings or Control Panel option is missing.

Fifth, check whether your computer is managed by a work or school organization. If BitLocker is controlled by company policy, you may not be allowed to disable it manually. Contact your IT administrator before changing encryption settings.

Find Your BitLocker Recovery Key Before Disabling BitLocker

Before you disable BitLocker, you should make sure your recovery key is saved. This is especially important if you are turning off BitLocker because of a TPM change, BIOS update, hardware repair, Windows update problem, or repeated BitLocker recovery screen.

You can check these common recovery key locations:

您的 Microsoft 帳戶。.

您的工作或學校帳戶。.

一份列印本。.

一支 USB 隨身碟。.

儲存於另一顆磁碟上的文字檔或螢幕截圖。.

貴組織的 IT 管理員。.

如果您無法手動找到該金鑰，, Magic Recovery Key 可協助掃描可存取的磁碟機，尋找其中儲存的 BitLocker 復原金鑰記錄、匯出的金鑰檔案、螢幕截圖、文件或其他可能包含復原資訊的本地端痕跡。.

Important: Magic Recovery Key cannot bypass BitLocker encryption, break a BitLocker password, or generate a missing recovery key. It can only help search for recovery key information that was previously saved or stored somewhere accessible.

This makes it useful before disabling BitLocker, changing TPM settings, reinstalling Windows, replacing hardware, or troubleshooting a BitLocker recovery screen.

Should You Disable BitLocker?

You may want to disable BitLocker if you are selling or donating your computer, changing drive encryption software, troubleshooting repeated BitLocker recovery prompts, or preparing a drive for a system migration.

However, you should not disable BitLocker only because it seems unfamiliar. BitLocker helps protect your data if your laptop is lost, stolen, or removed from the device. If your main concern is a temporary BIOS update or hardware change, suspending BitLocker may be a better option than fully turning it off.

Disable BitLocker only when you understand the security tradeoff and have backed up your important files and recovery key.

總結

To disable BitLocker on Windows 11 or Windows 10, open Manage BitLocker, select the encrypted drive, click Turn off BitLocker, and wait for Windows to decrypt the drive. If you use Windows 11 Home, you may need to turn off Device Encryption from Settings > Privacy & security > Device encryption instead.

If the normal option is missing, you can disable BitLocker with CMD by running manage-bde -off C: or with PowerShell by running Disable-BitLocker -MountPoint “C:”. After that, check the decryption progress with manage-bde -status or Get-BitLockerVolume.

Before turning BitLocker off, always save your BitLocker 復原 key and back up important files. If you only need to perform a BIOS update, TPM change, firmware update, or temporary hardware maintenance, suspending BitLocker may be safer than fully disabling it.

If you cannot find your BitLocker recovery key manually, Magic Recovery Key can help scan accessible drives for saved BitLocker recovery key records, exported key files, screenshots, documents, or other local traces that may contain recovery information. It cannot bypass BitLocker encryption, break a BitLocker password, or generate a missing recovery key, but it can help you search for recovery key information that was previously saved or stored somewhere accessible.

Is disabling BitLocker the same as suspending BitLocker?

No. Suspending BitLocker temporarily pauses protection without decrypting the drive. Disabling BitLocker turns BitLocker off and decrypts the drive. If you only need to update BIOS, change TPM settings, or perform temporary maintenance, suspending BitLocker is often better than disabling it completely.

停用 BitLocker 是否會刪除我的檔案？

Disabling BitLocker normally does not delete your files. It decrypts the selected drive and removes BitLocker protection after the process is complete. However, you should still back up important files before making encryption changes, especially on laptops, system drives, or drives with important work data.

Why can’t I find BitLocker on Windows 11 Home?

Standard BitLocker Drive Encryption is mainly available on Windows Pro, Enterprise, and Education editions. Many Windows 11 Home devices use Device Encryption instead. If you cannot find Manage BitLocker, open Settings > Privacy & security > Device encryption and check whether Device Encryption is turned on.

停用 BitLocker 需時多久？

The time depends on drive size, data amount, disk speed, and system performance. A small SSD may decrypt quickly, while a large drive with lots of data may take much longer. You can check progress in Manage BitLocker, Command Prompt with manage-bde -status, or PowerShell with Get-BitLockerVolume.

Should I disable BitLocker before a BIOS update?

If BitLocker is enabled, you should usually suspend BitLocker before a BIOS or firmware update instead of fully disabling it. Suspending protection helps avoid unexpected BitLocker recovery prompts while keeping the drive encrypted. After the update, you can resume BitLocker protection.

What should I do before disabling BitLocker?

Before disabling BitLocker, back up important files, save your BitLocker recovery key, keep the computer connected to power, and confirm that you are using an administrator account. If the computer is managed by a company or school, check with your IT administrator before changing encryption settings.
