Windows An Italian Windows site called "Windowsette" has published some purported secret Microsoft documents outlining some design and strategy plans for Windows 8. The Microsoft Kitchen blog has provided some analysis of the documents. The documents appear genuine, and there's lots of interesting information there.

Nitpick: Signing packages (which involves encryption) as an integrity check is part of the way that Linux package managers work. ...


I don't understand what you are saying here. DRM is not about package managers, it's about what those applications can do after they have been installed.

DRM can work like this:

- Download program Foo
- App manager verifies that it's okay and extracts the package. It stores the checksum of all the files it installs

- When the app is launched, it can access hidden data storage called FooSecrets (with encryption keys/whatever). It's the only application that can access that data storage.
- If you try to replace application Foo with your own application, kernel sees that checksum has changed. The application will run, but it will not allow you to access FooSecrets anymore.

FooSecrets is not accessible in the local file system - rather, it's in a "fritz chip" (trusted platform module). Only a pristine unmodified kernel can see the device, because it's enabled by the bootloader.
