Hi guys! You have being doing an amazing job here! I thanx U all so much! Well, lets begin the description of my problem. I have sucesfully slipstreamed sp3 with ie7 and wmp11 a lot of times, but since a week i'm obtaining a corrupted installation. The updates 951618 and 953838 haven´t slipstreamed correctly. After the installation the update 953838 can't be installed because some reason. The ie7 is very unstable (even more than normal ;-) ), and can't open the services.msc console to admin the services of the instalation. Can u help me please? Thx!!! EDIT: As you can see in the attachments, i've don't slipstremead the 951618 update. I've tried to remove the xpize setup, but the problem continues... HFNETCHK.zip
