Either by way of system Automatic Update or Microsoft website update, WMF update fails. System accessing the Automatic Update: 1. File downloads 2. Install process occurs 3. Get window stating not able to complete the update. 1., 2., 3. keep repeating over and over. Closed down all my system protections: Eset NOD32, Look-n-Stop, ProcessGuard, WinPatrol, Ghost, which did not help. Usually just need to shutdown the Look-n-Stop software firewall to accomplish WinXP SP2 updates. So downloaded the XP update from link in this webpage http://www.microsoft.com/technet/security/Bulletin/MS06-001.mspx . Ended up having to boot into Safe Mode to successfully complete the install. Tested sucessfully to block the WMF exploit. Did create a System Restore point before doing above.
