Since there is always a slight risk when updating the BIOS, it shouldn't be done needlessly on a machine out of warranty which I suspect your system is. In the event you need a newer BIOS update for a planned hardware upgrade or to correct a problem you are having then by all means a BIOS update is necessary. If you still wish to update the BIOS then try disconnecting all unneeded USB devices except for the keyboard and mouse. Also close out all unneed applications running in the background. Either of those two items can cause a problem with the BIOS update.
Although this is an old post I thought I would add some revelance to it so more people could fix their problems.
The suggestion to unplug USB devices and quit all other unused programs is fine but does not help the novice (Like Me) trying to fix the problem.
What I found to fix the Bios Update error "Windows Configuration Error" was to
1 Run MSConfig
2 Open Services and click "Hide all MS Services"
3 Click "Disable all Services" This will require a Restart. On startup I was then able to run the Bios Update.
Reverse the procedure to Enable your Services. It worked for me.
Dell needs a better search system. The 3 main words in my search were in this question but it was listed on page 3 instead of page 1. WHY
You can also run utility program called AUTORUNS and check for a DELL registry entry to see if a failed or stuck DELL BIOS update is pending in the registry that did not complete for some reason. You'll see DELL BIOS in the description field. That's what happened to be. It was looking for a file that the USER file area that it couldn't find. After I deleted the entry, the DELL BIOS update utility program ran correctly without the error message.
I've also run into this error on Windows 7 64-bit:
Windows Configuration Error
An error was encountered trying to configure Windows to
allow flashing, please reboot and try again. If this error
re-occurs, please contact technical help.
Even from Command Prompt this happened in safe mode, below I've posted a short video of what I did to get past the issue. Basically, I had to remove all the extra hardware on my machine, close all the other programs, and re-run the .exe files for my Dell Optiplex 330, which I downloaded from the Driver Downloads section of my Service Tag ID PC area.
Here is the video URL that shows what I ran into and how I fixed/updated my BIOS:
