Use new key on password change

This policy setting allows you to specify if a new encryption key is used when the password is changed.

If you enable or do not configure this policy setting, a new intermediate key is generated when the password is changed. This causes any extra key encryptors to be removed when the file is saved.

If you disable this policy setting, a new intermediate key is not generated when the password is changed.

Supported on: At least Windows 7
