If you're running RDS on a vSphere server with VMware Tools installed, you may wish to remove/hide the system tray icon. This can be done by setting a certain registry value.
The registry value is:
Change the value to 0 will effectively disable the icon the next time a user logs on.
In VMware ESXi 4.1, by default, the video drivers are not correctly installed. This is because of the fact that the old driver (which is installed by default) is a WDM type of driver. This type of driver has been kicked out of Windows 7 and Windows 2008R2 in favour of the newer WDDM driver architecture. As a result, the video is reverted to the Standard VGA adapter, which has terrible performance.
However, installing the VMware Tools does provide a correct driver, even though it is not installed by default. To install it, see the second chapter of the article: Windows 2008 R2 console freezes in vSphere console.
It is not possible to convert disk files from thick to thin, in-place. Instead, cloning the disk (or machine) allows you to change the provisioning type and thus enabling to have a thin disk. After the clone is complete, delete the original and you're good to go.
You can either clone a complete machine, or just clone a disk using the CLI or service console:
vmkfstools -i <srcDisk.vmdk> -d thin <dstDisk.vmdk>
