Microsoft to hand out Windows 7 "pre-betas" at PDC, WinHEC

We've already seen a few apparent Windows 7 screenshots and videos turn up, and it looks like there could soon be plenty more where those came from, as Microsoft has now officially announced that it'll be handing out "pre-beta" builds of the OS at both the Professional Developer Conference (PDC) in late October and the Windows Hardware Engineering Conference (WinHEC) in early November. As we had heard previously, you can also expect to hear plenty of technical details about the OS straight from Microsoft at PDC and, who knows, we may even get word of an actual release date.
