Hi GMan, thanks for your greeting and reply.
Send unique Player ID to content providers option seems to be meant for stream content from the Internet. That is not my usage case. What I need to do is to play DRM Windows Media files (WMA or WMV). There are lots of DRM Audiobooks and video from public libraries' digital collections (as well as in the corporate library at Microsoft) that is free of charge. I've been enjoying them in all earlier Windows versions. For that to work, the WMP requires the Security Component upgrade, that is why I need the IE 10 to support the individualization page (Security component upgrade) to do just that.
Surely I hope that Windows 8 could continue to support Microsoft's own DRM at Desktop mode. Anyone has insights to it?
