Windows 7 updates not installable

Hi,

For the company, we have bought 2 vostro 470 desktops, which have been delivered this month.

After startup and preparing for first use, windows 7 downloads and installs its updates.

However, after a few update installs, the other installs fail ("windows update error 800B0100, code 80244018). Trying to fix this with the windows 'fix it' does not solve the problem and any other updates fail.

I have already reset the pc to its factory condition, but the same problem appears.

What can be the problem here ?

Thanks
