I found a soulution to this problem. I dont know if it is deleting the drivers completely, but it makes them go away.
I found it on the Cakewalk Forum.
"To get rid of the Magix Low Latency ASIO driver:
Go into the Registry...
HKEY_LOCAL_MACHINE\SOFTWARE\ASIO - delete the Magix Low Latency ASIO driver entry
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\ASIO - delete the Magix Low Latency ASIO driver entry
If you've got a piece of hardware that functions as an ASIO audio interface (and you know you don't want to use it), you can use this same procedure to eliminate that particular ASIO driver."
