From
the
Start
menu,
select

Services
.
Your
virtual
service
application
appears
in
the
list
of
services.
You
can
manage
the
service
in
the
same
way
as
any
natively
installed
service.
Using ThinApp Packages Streamed from the Network
Any
network
storage
device
can
serve
as
a
streaming
server
for
hundreds
or
thousands
of
client
computers.
See
Figure 3
‐

Figure 3-1.
Data Block Streaming over a Network Share
On
the
end
‐
user
desktop,
you
can
create
shortcuts
that
point
to
the
centrally
hosted
executable
file
packages.
When
the
user
clicks
the
shortcut,
the
application
begins
streaming
to
the
client
computer.
During
the
initial
streaming
startup
process,
the
ThinApp
status
bar
informs
the
user
of
the
progress.
How ThinApp Application Streaming Works
When
you
place
compressed
ThinApp
executable
files
on
a
network
share
or
USB
flash
drive,
the
contents
from
the
executable
file
stream
to
client
computers
in
a
block
‐
based
fashion.
As
an
application
requests
specific
parts
of
data
files,
ThinApp
reads
this
information
in
the
compressed
format
over
the
network
using
standard
Windows
file
sharing
protocol.
For
a
view
of
the
process,
see
Figure 3
‐
2
.
After
a
client
computer
receives
data,
ThinApp
decompresses
the
data
directly
to
memory.
Because
ThinApp
does
not
write
data
to
the
disk,
the
process
is
fast.
A
large
package
does
not
necessarily
take
a
long
time
to
load
over
the
network
and
the
package
size
does
not
affect
the
startup
time
of
an
application.
If
you
add
an
extra
20GB
file
to
a
package
that
is
not
in
use
at
runtime,
the
package
loads
at
the
same
speed.
If
the
application
opens
and
reads
32KB
of
data
from
the
20GB
file,
ThinApp
only
requests
32KB
of
data.
The
ThinApp
runtime
client
is
a
small
part
of
the
executable
file
package.
When
ThinApp
loads
the
runtime
client,
it
sets
up
the
environment
and
starts
the
target
executable
file.
The
target
executable
file
accesses
other
parts
of
the
application
stored
in
the
virtual
operating
system.
The
runtime
client
intercepts
such
requests
and
serves
them
by
loading
DLLs
from
the
virtual
operating
system.
The
load
time
of
the
runtime
client
across
a
network
is
a
few
milliseconds.
After
ThinApp
loads
the
runtime
client
to
memory
on
the
client
computer,
the
end
‐
user
computer
calculates
which
blocks
of
data
are
required
from
the
server
and
reads
them
based
on
application
activity.
When
the
application
makes
subsequent
read
requests
for
the
same
data,
the
Windows
disk
cache
provides
data
without
requiring
a
network
read
operation.
If
the
client
computer
runs
low
on
memory,
Windows
discards
some
of
its
disk
cache
and
provides
the
memory
resource
to
other
applications.
