Vista today, post-Service Pack 2, which is now in the marketplace, is the safest, most reliable OS we’ve ever built. It’s also the most secure OS on the planet, including Linux and open source and Apple Leopard. It’s the safest and most secure OS on the planet today. Everything that we’ve learned in Vista will be leveraged in Windows 7, but certainly when we broke a lot of the compatibility issues to lock down user account controls, to lock down the ability to manipulate states and all the things, that was a very painful process for us to grow through, but we had to do it. And the reason that Windows 7 will be successful is because of the pain we took on Vista. Because from a compatibility standpoint, if it works on Vista, it will work on Windows 7. If it doesn’t work on Vista, it won’t work on Windows 7.

I got nothing.

Microsoft has announced that Vista’s SP1 will fail on install if you’re dual-booting, thanks to “Trusted Computing”‘s chain of trust being broken.

If you scoff at TC, I can vouch that the system works well.  For instance, Microsoft broke my “chain of trust” a few years ago causing me to not allow it to install on my computer. No problems since.
