Seriously, no. They are just concerned about opening cases and changing parts but even then they have to be flexible. It is the nature of the beast.Will Changing the operating system effect the dell warranty?The warranty doesn't cover software, so no, it has no affect on your warranty.
(Note: %26quot;affect%26quot; is not the same as %26quot;effect%26quot;... you mean %26quot;affect%26quot; in this case)
