Mouse settings via TD or registries?

Couldn't find the settings in TD, nor the solution in the
newsgroup. If someone knows, please help me out. Thanks.

Does anyone know how to set the mouse speed in advance via
TD or registries? Since the mouse speed is slow in our
system, and since we don't want to show the control panel,
I am sure that one can set it via registries. I
used "AShampoo" (like RegMon), and found out that the
registry "HKEY_USERS\<current user's number>\Control
Panel\Mouse\MouseSensitivity" will be set to "20" when
setting the mouse speed to the max. Is it safe to just
play with this number?

Thanks.
