Driver update for Latitude E4300

Hi, I bought 2 weeks ago a Dell Latitude E4300, a small laptop, Win7,
64-bit.

It had a fingerprint sensor and an ID card sensor. They don't have
their software anymore, because win7 was re-installed, but that implies
to me the computer was used in a corporate or government environment.

(It also had IIUC the ability to do a special fast boot that would
enable it only to get email. It used separate boot files that were hard
coded somewhere iiuc, but I'm sure that also required software I don't
have now. That's okay because I'm not some executive who has to read
his email every 20 minutes. And in practice I would never turn the
computer on only to get email. Even if I only planned that, the email
might make me want to check the web for something.)

I probably have lots of questions, but this is the first one.

I went to dell support, entered the tag number, and ran the driver
checkup and it listed 9 drivers to be updated!!!

Gosh that's hard to believe.

Video, Chipset, Video Graphics, Audio, Bios, Mouse/Keyboard, Network,
Network Wireless, Serial ATA.

That's almost everything. (What's left?) Even though the thing seems to
be working fine now. Should I install them one at a time or all at
once?

It says "Auto Installation not available. Please try again later or
manually download nad install individual updates." Is this one of
those times when later will never come? Or should I wait?

This would imply the previous owner never updated drivers at all, and
that seems surprising in a corporate environment. Or not??

Thanks.
