Windows To Go operates just like any other installation of Windows with a few exceptions. These exceptions are:
Hibernate and sleep are disabled by default. To help prevent Windows To Go from accidental data corruption during roaming hibernate and sleep are disabled. They can be re-enabled by using Group Policy settings.
Internal disks are offline. To ensure data isn't accidentally disclosed, internal hard disks on the host computer are offline by default when booted into a Windows To Go. Similarly if a Windows To Go drive is inserted into a running system the Windows To Go drive will not be listed in Windows Explorer.
Trusted Platform Module (TPM) isn't used. When using BitLocker Drive Encryption a pre-operating system boot password will be used for security rather than the TPM since the TPM is tied to a specific computer and Windows To Go drives will move between computers.
Windows Recovery Environment isn't available. In the rare case that you need to recover your Windows To Go drive, you should re-image it with a fresh image of Windows.
Push Button Reset isn't available. Resetting to the manufacturer's standard for the computer doesn't really apply when running Windows To Go, so the feature was disabled.
