Yea, I was caught off guard to see there's a Get Windows 10 icon sitting next to my clock this morning (especially on a corporate PC which wasn't eligible for the free upgrade, at in what they had previously explained.)
I don't have a test machine to play around with it, but it sounds better than Windows 8.1 and that's all I really want.
Well, it could but you would need help. BOINC clients show you more data than F@H does, but the F@H servers would know the client ID and IP address of submissions.
