及时更新WM DRM License Server Information，拒绝恶意播放器

刚才试了一下，只要打开这个页面： http://licenseserver.windowsmedia.com/v2revocation.asp 就可以更新License Server的Revocation List（DRM Component撤回清单/废除清单？）。

页面里内嵌一段JavaScript，内容详见页尾。

所以，如果你有幸从微软申请到一份Client DRM Component，请妥善保管，千万不要滥用。否则，微软在接到举报后，就会把你手中DRM Component的Key添加到这份清单里。
