> What about getting vendors into changing their patching habbits? Instead of packing some hundred mega patches just provide micro ones when needed?

This was how things worked previously in the industry. There are a number of disadvantages to companies releasing multiple small patches throughout the month:

1. Users may have to reboot their computers multiple times a week.

2. Large corporations (with their own back-compat worries) do their own extensive validation of patches. Multiple small patches puts a large seriously burden on IT departments.

The industry has moved towards larger update bundles for good reason.
