I'm running Windows XP Media Center (SP3) and IE7. I have only one USER on my PC, with Admin. Privileges. Recent crashes of IE 7 - for unknown reasons - caused me to disable add-on's and then see if the problem continued. They did. So, I then attempted to access Internet options under the tools menu so I could delete old files, or even reset IE7 to defaults. When attempting to access these controls, I'm greeted with an access violation message informing me that I don't have access to these controls, and I need to contact my sys. admin. Well, he and I are both in trouble since we're one in the same and have no clue how to get around this restriction. I've checked my user account to ensure it does indeed have admin. privileges. I then attempted to access the internet options through the control panel, but XP simply locks-up when I do that. Evidently, something is working really hard to make sure I can't access those settings. Read on another forum that I may have inadvertantly caused problems with IE7 by installing XP SP3 "on top" of it. The article indicated IE7 should have been uninstalled prior to installing SP3, then reinstalled afterwards. Well, its too late to do that NOW. Thanks, Microsoft. Anyway, if any of you good folks have a possible solution to my problem, I'd really appreciate hearing it.
