From another thread -
Emphasis mine. So, basically, if you have an issue you cannot resolve yourself then support will officially look into it.
We're fully aware that Windows 10 is rolling out in two days. This is indeed an event, and if we had considered otherwise that would have been very silly on our part.
We've been testing the compatibility of Elite: Dangerous and Windows 10, and are doing our best to ensure players upgrading Windows will experience minimum interruptions with their game. Now, we can't speak on Microsoft's behalf to say the OS itself will be entirely flawless on release but we certainly hope it will!
If there are any specific issues you come across after upgrading, please do get in touch and we'll address these as quickly as we can.
