http://www.microsoft.com/technet/security/Bulletin/MS07-017.mspx Do it now. Looks straight up, did not seem to load anything un wanted. Reboot after load just to be sure. This exploit can even be hid in a .jpeg file so patch your system. I just got the message from the national alert system even as I was following this the last couple of days waiting for the patch release. Know what OS you have and load the correct version. Not everybody is affected.
