I just reformatted a drive on a Dell Latitude D600 laptop, XP Pro I see in other posts that you seem to understand the event viewer. I googled for hours and could not come up with a solution. The Event ID is 1041, userenv stating under description: Windows cannot query DllName registry editor for {7B849a69-220F-451E-B3FE-2CB811AF94AE} and it will not be loaded. Tis most likely caused by a faulty registration. Do you know of any way to fix that error? Thanks Some HELP in posting on Computing.net plus free progs and instructions Cheers

Hopefully, http://www.microsoft.com/communitie... or http://www.microsoft.com/communitie... and both seem to be related to uninstall of IE8. Fix was to delete the guid in the registry. Silence is golden but duct tape is silver

Thanks syslock. I had found the the 1st link while googling and yours had a few more comments on it. The 2nd link was a new one to me. Yes, I had tried IE8 and it was so painfully slow on the fresh install that I uninstalled and went back to IE7. I also tried deleting the faulty registration, but it just makes a new registry entry and the error comes back in the event viewer. I'm surprised Jefro didn't answer yet, he seems to push the event viewer in most of his posts so I figured he might be real knowledgeable in that area. I'm sure it's not a virus or trojan as I have scanned with many cleaners and AV's. Thanks for the reply Some HELP in posting on Computing.net plus free progs and instructions Cheers

Sorry, I was doing my taxes, so I can bail out bank execs. I sure don't want them to miss their bonus. IE8 beta is slow, The RC is faster. As to problem. If you think it is IE8, consider a system restore to a time before you installed IE8. It would do a better job than un-install normally. I would think that if a registry keeps popping up there is some service that has admin access to reg. Start with autoruns maybe. MRT also. "Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

I also found some info about the gpextensions and most of them had to do with group policies. Identifying Group Policy Client-Side Extensions How Administrative Templates Extension Works Interpreting Userenv log files will provide maybe some helpful info in troubleshooting. I had also seen a reference to it being profile related and maybe creating a new profile may tell if the issue is related to it or not. I would agree that some service Silence is golden but duct tape is silver

Thanks for all the great replies. My client picked up the laptop today and will notify me if he has any more problems with it. It confused me how a fresh reformatted install could have those problems. Thanks again! Some HELP in posting on Computing.net plus free progs and instructions Cheers
