The primary contact for the support request will receive email notifications when a case is created, assigned to a service engineer to investigate, and mitigated. If, at any point, you have a question about the case, the best way to get in touch is to reply directly to one of those emails. If we have questions about your request or need more details, we'll email the primary contact listed on the support requests.

|

|

When a computer with an encrypted hard drive is in a powered-off state, the drive locks automatically. As a computer powers on, the device remains in a locked state and is only unlocked after the AK decrypts the DEK. Once the AK decrypts the DEK, read-write operations can take place on the device.
|
||||
|
||||
When writing data to the drive, it passes through an encryption engine before the write operation completes. Likewise, reading data from the drive requires the encryption engine to decrypt the data before passing that data back to the user. If the DEK needs to be changed or erased, the data on the drive doesn't need to be re-encrypted. A new Authentication Key needs to be created and it will re-encrypt the DEK. Once completed, the DEK can now be unlocked using the new AK, and read-writes to the volume can continue.

## High Efficiency Video Coding (HEVC) support
|

<!--7475101-->
|
||||
Starting in Windows 11, version 22H2, support for High Efficiency Video Coding (HEVC) is now available. You can play HEVC videos in any video app on your Windows 11 device. HEVC is designed to take advantage of hardware capabilities on some newer devices to support 4K and Ultra HD content.
|
||||
For devices that don't have hardware support for HEVC videos, software support is provided, but the playback experience might vary based on the video resolution and your devices performance.
