Ok, the problem is solved in my case.\n\nI removed KB897715 from "add/remove programs", after that a system reboot.\nThen installed KB823353 manually, not from windows update, after that a\nsystem reboot. Then, check "add/remove programs" list and see if Q823353\nappears in the list. Install KB897715 manually, not from windows update, a\nsystem reboot. Then check that KB897715 appear in the "add/remove..." list\nand Q823353 dissappeared. Then I checked windows update and everything was ok.\n\nThanks a lot.
