truecrypt是款不错的加密软件，不过很多人加密后使用后不想保留加密了，想去掉。但是不知道正确的方法

其实官网说的很清了

How to Remove Encryption

Please note that TrueCrypt can in-place decrypt only system partitions and system drives (select System > Permanently Decrypt System Partition/Drive). If you need to remove encryption (e.g., if you no longer need encryption) from a non-system volume, please follow these steps:

1. Mount your TrueCrypt volume.
2. Move all files from the TrueCrypt volume to any location outside the TrueCrypt volume (note that the files will be decrypted on the fly).
3. Dismount the TrueCrypt volume.
4. If the TrueCrypt volume is file-hosted, delete it (the container) just like you delete any other file.
   
   If the volume is partition-hosted (applies also to USB flash drives), in addition to the steps 1-3, do the following:
   1. Right-click the 'Computer' (or 'My Computer') icon on your desktop, or in the Start Menu, and select Manage. The 'Computer Management' window should appear.
   2. In the Computer Management window, from the list on the left, select 'Disk Management' (within the Storagesub-tree).
   3. Right-click the partition you want to decrypt and select 'Change Drive Letter and Paths'.
   4. The 'Change Drive Letter and Paths' window should appear. If no drive letter is displayed in the window, click Add. Otherwise, click Cancel.
      If you clicked Add, then in the 'Add Drive Letter or Path' (which should have appeared), select a drive letter you want to assign to the partition and click OK.
   5. In the Computer Management window, right-click the partition you want to decrypt again and select Format. The Formatwindow should appear.
   6. In the Format window, click OK. After the partition is formatted, it will no longer be required to mount it with TrueCrypt to be able to save or load files to/from the partition.
   If the volume is device-hosted(i.e., there are no partitions on the device, and the device is entirely encrypted), in addition to the steps 1-3, do the following:
   1. Right-click the 'Computer' (or 'My Computer') icon on your desktop, or in the Start Menu, and select Manage. The 'Computer Management' window should appear.
   2. In the Computer Management window, from the list on the left, select 'Disk Management' (within the Storagesub-tree).
   3. The 'Initialize Disk' window should appear. Use it to initialize the disk.
   4. In the 'Computer Management' window, right-click the area representing the storage space of the encrypted device and select 'New Partition' or 'New Simple Volume'.
   5. WARNING: Before you continue, make sure you have selected the correct device, as all files stored on it will be lost. The 'New Partition Wizard' or 'New Simple Volume Wizard' window should appear now; follow its instructions to create a new partition on the device. After the partition is created, it will no longer be required to mount the device with TrueCrypt to be able to save or load files to/from the device.

简单的说如果是文件加密，就当做普通文件删除即可。

如果你把一个系统分区或移动硬盘上的一个分区完整加密了，就打开操作系统的磁盘管理(右键我的电脑-管理-磁盘管理)在你加密的那个分区(卷)右键，改变驱动器名和路径，换成别的，比如原来是Y换成P，这样还不行，必须再把P格式化就可以了。

如果当初想我一个加密有隐藏分区了，就手动添加一个分卷，重复上面的操作即可。

说的不是很清，上面的官网英文说的很仔细了，也不难看懂。
