Ultra VNC is by far the best of its kind and I think they found an idea to make some money and compensate them for the hard work.
TeamViewer is one subset, and this one, "Instant House Call" (the right side of the screen) is another one,

I usualy build a directory with these few files (no need even to install) and it takes care of every thing needed for the Serevr, or the Client.
MSRC4Plugin_NoReg .dsm - 16 KB (AES Encryption Module).
rc4.key - 87 bytes (Encryption key).
vncviewer.exe - 1.5 MB (VNC Viewer).
winvnc.exe - 1.5 MB (VNC Server).
ultravnc.ini - 760 Bytes (config file).
If a computer needs to be controlled frequently the Server can be loaded as Service at Startup and run in the background.
When used this way the Registry is Not used and thus no residual leftovers.
These five files about 3.5MB ( + configuration of Firewalls ports when needed) is all that is needed to fully control locally or through the Internet and computer running Win200, Vista, Win7.
