Personal Data Encryption

---

Personal data encryption (PDE) is a security feature introduced in Windows 11, version
22H2 that provides additional encryption features to Windows. PDE differs from
BitLocker in that it encrypts individual files instead of whole volumes and disks. PDE
occurs in addition to other encryption methods such as BitLocker.
PDE utilizes Windows Hello for Business to link data encryption keys with user
credentials. This feature can minimize the number of credentials the user has to
remember to gain access to files. For example, when using BitLocker with PIN, a user
would need to authenticate twice - once with the BitLocker PIN and a second time with
Windows credentials. This requirement requires users to remember two different
credentials. With PDE, users only need to enter one set of credentials via Windows Hello
for Business.

version 22H2 clients.

Starting in Windows 11, version 22H2, you can deploy education themes to your
devices. The education themes are designed for students using devices in a school.
Themes allow the end user to quickly configure the look and feel of the device, with

themes, making it feel the device is their own.
