Updated: March 3, 2014

Applies To: Windows 8.1, Windows PowerShell 4.0, Windows Server 2012 R2

Suspend-BitLocker

Suspends Bitlocker encryption for the specified volume.

Syntax

Parameter Set: Default
Suspend-BitLocker [-MountPoint] <String[]> [[-RebootCount] <Int32> ] [-Confirm] [-WhatIf] [ <CommonParameters>]




Detailed Description

The Suspend-BitLocker cmdlet suspends Bitlocker encryption, allowing users to access encrypted data on a volume that uses BitLocker Drive Encryption. This cmdlet makes the encryption key available in the clear.

Suspension of BitLocker does not mean that BitLocker decrypts data on the volume. Instead, suspension makes key used to decrypt the data available to everyone in the clear. New data written to the disk is still encrypted.

While suspended, BitLocker does not validate system integrity at start up. You might suspend BitLocker protection for firmware upgrades or system updates.

You can specify the number of times that a computer restarts before the BitLocker suspension ends by using the RebootCount parameter, or you can use the Resume-BitLocker cmdlet to manually resume protection. If you do not specify the RebootCount parameter, the cmdlet uses a value of one (1), so BitLocker protection resumes after the next restart.

For an overview of BitLocker, see BitLocker Drive Encryption Overview (http://technet.microsoft.com/en-us/library/cc732774.aspx) on TechNet.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

  • BitLockerVolume[], String[]

Outputs

The output type is the type of the objects that the cmdlet emits.

  • BitLockerVolume[]

Examples

Example 1: Suspend BitLocker protection

This command suspends Bitlocker encryption on the BitLocker volume specified by the MountPoint parameter. Because the RebootCount parameter value is 0, BitLocker encryption remains suspended until you run the Resume-BitLocker cmdlet.


PS C:\> Suspend-BitLocker -MountPoint "C:" -RebootCount 0
