Cluster service fails when shutting down or data deduplication fails with "Drive is locked" in Windows Server 2012 R2

This article describes two issues that are addressed in this update: the cluster service fails when it's being shut down and data deduplication fails with the "This drive is locked by BitLocker Drive Encryption. You must unlock this drive from Control Panel" error message in Windows Server 2012 R2. Before you install this update, see the Prerequisites section.
Issus that are fixed in this update

Issue 1

Critical error occurs when you shut down the cluster service. For example, the "[Shutdown] Groups failed to terminate in a timely manner. Cluster service will exit." error message is logged when you shut down the cluster service.

Issue 2

Data deduplication doesn't work on a BitLocker-encrypted cluster shared volume (CSV) provisioned by using a tiered storage space. It fails even if the drive is unlocked, and the following error message is logged:

This drive is locked by BitLocker Drive Encryption. You must unlock this drive from Control Panel
