Setting Description
Bitmap cache file size in
unit for number bpp bitmaps
Species the size of the bitmap cache, in kilobytes or megabytes, to use for specic
bits per pixel (bpp) bitmap color seings.
Separate versions of this seing are provided for the following unit and bpp
combinations:
n
KB/8bpp
n
MB/8bpp
n
MB/16bpp
n
MB/24bpp
n
MB/32bpp
Bitmap caching/cache
persistence active
Determines whether persistent bitmap caching is used (active). Persistent bitmap
caching can improve performance, but it requires additional disk space.
Color depth
Species the color depth of the remote desktop. Select one of the available seings:
n
8 bit
n
15 bit
n
16 bit
n
24 bit
n
32 bit
For 24-bit Windows XP systems, you must enable the Limit Maximum Color Depth
policy in Computer  > Administrative Templates > Windows
Components > Terminal Services and set it to 24 bits.
Cursor shadow
Determines whether a shadow appears under the cursor on the remote desktop.
Desktop background
Determines whether the desktop background appears when clients connect to a
remote desktop.
Desktop composition
(Windows Vista or later) Determines whether desktop composition is enabled on
the remote desktop.
When desktop composition is enabled, individual windows no longer draw
directly to the screen or primary display device as they did in previous versions of
Microsoft Windows. Instead, drawing is redirected to o-screen surfaces in video
memory, which are then rendered into a desktop image and presented on the
display.
Enable compression
Determines whether RDP data is compressed. This seing is enabled by default.
Enable RDP Auto-Reconnect
Determines whether the RDP client component aempts to reconnect to a remote
desktop after an RDP protocol connection failure. This seing has no eect if the
Use secure tunnel connection to desktop option is enabled in Horizon
Administrator. This seing is disabled by default.
Font smoothing
(Windows Vista or later) Determines whether anti-aliasing is applied to the fonts
on the remote desktop.
Menu and window animation
Determines whether animation for menus and windows is enabled when clients
connect to a remote desktop.
Redirect clipboard
Determines whether the local clipboard information is redirected when clients
connect to the remote desktop.
Redirect drives
Determines whether local disk drives are redirected when clients connect to the
remote desktop. By default, local drives are redirected.
Enabling this seing, or leaving it uncongured, allows data on the redirected
drive on the remote desktop to be copied to the drive on the client computer.
Disable this seing if allowing data to pass from the remote desktop to users' client
computers represents a potential security risk in your deployment. Another
approach is to disable folder redirection in the remote desktop virtual machine by
enabling the Microsoft Windows group policy seing, Do not allow drive
redirection.
The Redirect drives seing applies to RDP only.
