They once shipped my company a custom MSVCRT.DLL to fix a crash bug in a third-party application under heavy load. True, it was a bug in the C runtime itself, but they got us a fix for it about a day after we (along with the third party) got in touch with them.

Just a few years later my team had to contact them for a BSOD that kept happening after one of their patches. We were put off for about a week before throwing our hands up on it.
