# Personal Data Encryption

(*Applies to: Windows 11, version 22H2 and later*)
Personal data encryption (PDE) is
Personal data encryption (PDE) is a security feature introduced in Windows 11, version 22H2 that provides encryption of individual user files in the known user folders of **Documents**, **Pictures**, and **Desktop**. PDE occurs in addition to other encryption methods such as BitLocker.
PDE utilizes Windows Hello for Business (WHfB) to link data encryption keys with user credentials. This can minimizes the amount of credentials the user has to remember to gain access to files. Unlike BitLocker which unlocks data encryption keys at boot, PDE does not unlock data encryption keys until a user logs via WHfB.
## Differences between PDE and BitLocker
| Item | PDE | BitLocker |
|--|--|--|
| Release of encryption keys | At user logon via WHfB | At boot |
| Encryption keys discarded | At user logoff | At reboot |
| Files encrypted | User known folders of Documents, Pictures, and Desktop | Entire volume/drive |
