Microsoft Developer Division has started DevDiv Hotfix Public Availability Pilot Program. This is a program where hotfixes are made available to the general public. The fixes are not as ruggedly tested as a Service Pack, but if you happen to run into a specific problem the fix may just be the solution for you.
