data    and settings    are stored  on  the user    profile disk,   since   Documents   is  part    of  the
user    profile area.   On  subsequent  logons  by  the user,   the user    profile disk    VHDX    is
attached    to  the required    VM  image   or  RD  Session Host,   providing   the same    user
profile area    and therefore   the same    user    experience  and data    access. Within  the virtual
desktop that    is  using   the user    profile disk,   the VHDX    is  seen    as  mounted for the
location    of  the user’s  profile using   the MOUNTVOL    command.
User    profile disks   can be  enabled when    creating    a   VDI or  session-based   pool    or  after
the creation    of  the pool.   Granular    control of  the data    stored  on  the user    profile disk    is
possible,   as  shown   in  Figure  11.7;   a   maximum size    for the data    stored  on  the VHDX    is
also    shown.

Using   user    profile disks   has some    advantages  and disadvantages.  The big advantage   is
that    they    are easy    to  use and provide users   with    a   consistent  profile and data
