First of all go to the sub domain: http://badvista.fsf.org/ and read carefully all the interesting things the Free Software Foundation says about Vista, DRM, Trusted Computing, etc. and your (digital) freedom.

In synthesis:

• Microsoft’s new Windows Vista operating system is a giant step backward for your freedoms


• Vista has DRM: digital rights management


• These features will make your computer less reliable and less secure


• Digital rights management (DRM) features built into Vista at the behest of the entertainment industry - And you don’t get to refuse them


• Vista decide which programs you can and can’t use on your computer


• Vista decide which features of your computer or software you can use at any given moment


• Vista force you to install new programs even when you don’t want to (and, of course, pay for the privilege)


• Vista restrict your access to certain programs and even to your own data files


• Vista and its Defender is free to delete files on your PC


• Vista and its Genuine Advantage decide what to do (install or not) with thirdy party developed software


• DRM is enforced by technological barriers


• Your computer has to be constantly monitoring what you are doing consuming a lot of resources (disk space, cpu time)


• Microsoft and other computer companies sometimes refer to these restrictions as “Trusted Computing.” Given that they are designed to make it so that your computer stops trusting you and starts trusting Microsoft, these restrictions are more appropriately called “Treacherous Computing”.
