Are you sure there are updated iso files?
My understanding was that whenever Dell makes a new iso file available, it could be downloaded with existing service tags, but maybe I'm mistaken about that.
Anyway, if you provide a service tag that qualifies for a file that's not yet available through the tool, just let me know the tag, and I'll make an update available.

As I said the systems shipped with a Dell Windows Vista "Edition" Reinstallation DVD, Dell did not provide a ISO file to Download. In any case the Operating System Reached End of Life 2 years ago and is no longer supported by Microsoft.
All systems Dell sold with Windows Vista are over a decade old and long past the system's warranty period so not supported by Dell either... These 2006-2009 models should run Windows 10 32 Bit without an issue. At this stage running Windows 10 32 Bit even unlicensed without a Product Key is more functional (even with all the personalisation options greyed out) and more secure than running Windows Vista 32 Bit.

The ISOs I mentioned above are unmodified and listed using the Windows ISO Download Tool. They contain all the languages listed above (note they do not contain English UK). I would personally recommend using Microsoft's Windows 10 ISO over the Dell Windows 10 ISO.

I also have a few Windows XP Dell OEM images but not from service tags. I got them years ago and they are still sitting on my hard drive😁. The Windows 7 image was last updated in 2016... Unlikely Dell is going to update it...
Not sure if it is possible to find a service tag that could unlock Windows XP Downloads.
