You manage a pooled AVD host pool where FSLogix Profile Containers are stored on an Azure Files share. Users report that after several weeks, the share is filling rapidly even though individual profiles are relatively small. Investigation shows each user's profile VHDX file was created at its maximum configured size regardless of actual data stored. You need to reduce storage consumption so that profile disks consume only the space actually used, while retaining the configured maximum size ceiling. Which FSLogix registry setting should you configure?
