They ain't no work around to that, that is exactly what MS made the thing for. it's a code encrypted directly into the media file. After a set time period the license runs out and the file will not play. Some versions apparently delete themselves when the expiration is past.
I've downloaded porn videos a few times that when you click properties on them there's a 3rd tab on the top of the file with license on the tab. Open it and you will see who the owner is and when it expires. It also will ask for your user password if you used a spoofing proggy to download the file. It's a way they can make there file's useless to people that are gaining access to them illegally. These files also cannot be modified in any form that will alter or remove the DRM, I've tried re-encoding it with several encoding proggys and even tried to convert them to a different file type, no good. It gives an error when you try to save it.
Worse yet is the next version of windows thats coming out, it will have a key and registration that if not properly regestered with MS it will deactivate the drive!
Microsoft’s Bill Gates has gone on record that the next big version of Windows, codenamed Longhorn, will have something called Trusted Computing (
www.trustedcomputinggroup.org) at its very core. This is a cross-industry initiative, which incorporates the successor to Microsoft’s infamous Palladium. The idea is to have authentication and encryption chips hardwired into your PC, so the OS can control what you can and can’t do. That way, if your subscription to Microsoft Word runs out, it could disappear from your system. You can forget about writing any more documents, and maybe even viewing the ones you’ve already written as well.
