Hi,
FSLogix solutions include:Profile Container, Office Container, Application Masking and Java Version Control. It simplifies the management of applications and 'Gold Images'. So we just need to install the FSLogix App on the computers that deploys in the on non-persistent environments.
Office Container redirects only areas of the profile that are specific to Microsoft Office, and is a subset of Profile Container. Office Container enables and enhances the Microsoft Office experience in non-persistent environments. Office Container will generally be implemented with another profile solution. Other solutions must be configured to exclude the portions of the profile managed by Office Container.
for more information about the office container, refer to this link.
