Hello, this is a great site. Although I haven’t found a similar issue as mine, I did find a lot of other interesting info. while I was doing searches. Maybe I found the solution, but didn’t know it.

Well, this will be long, but I wanted to show what I have done so far to resolve this. I have a Dell XPS410 running Windows XP MSE 2005. The issue stared approximately 3 weeks ago. After booting up I would get the dialog box saying that Windows had found new software and needed to load a driver. The driver it needed was “Microsoft UAA Driver for High Definition Audio”. This seemed strange as I have good sound and everything seems to run fine. I checked the BIOS to make sure the integrated audio was turned off since I use a sound card. I tried using the XP disks, MSE2005 disk, the Dell forum, many searches on the internet and Microsoft web site to find the driver without any luck. Microsoft did have a hot fix, KB Article Number: 888111. The e-mail I received with instructions on how to download the fix had warnings that scared me. This was more than just a driver fix. Someone told me to check the System devices in the Device Mgr and it could help locate the problem. When I checked the Device Mgr I discovered that my System devices folder is gone. I can’t help think these are related. I previously posted the problem for the missing problem of the missing UAA driver, but I wasn't aware of the system devices folder missing.

Last night I ran SuperAntiSpyware and Malware Bytes and did find 5 tracking cookies which I quarantined. I ran a full system scan with Avast and the Eset online scanner and both came up clean. I deleted all of my restore points and ran the spy ware programs again and came up clean.

Today I ran sfc /scannow with my installation disks and towards the end it prompted me that it needed to load a driver and which disk to put in. The only problem I had was when it would tell me to put Win XP disk 2 in. I always got the message that I had the wrong disk in even though I had the correct one. Out of desperation I tried the MSE disk and got the same response. To finish I had to keep ignoring the prompts. I copies all of the messages from the Event Manager which told me which drivers were needed and that they could not be copied into the DLL cache with a specific error code 0x800b0100. I did some searches on this and found many results, but none seemed to match.

If anyone can help me I would really appreciate it. I am almost burned out and if it wasn’t for the “found new hardware” and missing System devices folder I think I would leave it alone.

I have to leave right now, but I will check back tomorrow for any suggestions, try them and the post back with the results.

Thank you,
Bill

Thanks for responding.

Yes they are all up to date. Someone suggested uninstalling SP 3 and then reloading it since it has the UAA Bus Driver in it, but with the subsequent patches, hot fixes, etc I was afraid to do it. . I don't know if that would restore the System devices anyway. I haven't the sightest idea how to restore the System devices folder in the Device Manager without doing the "R" word. It hasn't been that long since I did a reformat and install, Sept 09.

I am open to any and all suggestions.

Thanks.

Thank you Mark for the links. I will give them a try. :thumbsup: Will this restore the System devices folder in the Device Manager? I was thinking that this may have been the problem in trying to install the driver. I'll let you know how things turn out.

Thanks again,
Bill

Not sure, I'll have to check it out

IIRC
UAA must be installed before the sound driver
