Microsoft has just announced that it will permit Flash content to run by default in both Windows RT and Windows 8 beginning tomorrow, March 12th. Until now, compatibility in Internet Explorer 10 has been limited to a select number of sites whitelisted by Microsoft. (Windows 8's traditional desktop mode has offered full Flash support from the get-go.) But moving forward — and after users apply a software update — the inverse will be true. Microsoft has apparently concluded that web developers have made sufficient progress in bringing touch interactivity to Flash content. "As we have seen through testing over the past several months, the vast majority of sites with Flash content are now compatible with the Windows experience for touch, performance, and battery life."
