Download Windows 7 Virtual PC and XP Mode on alternate computer

I just purchased a SYX Mid-Tower ATX Computer from Tiger Direct and it has the capability to run the Windows XP mode and the Virtual Mode. I have an OEM Windows 7 Professional 64 bit OS.
My problem is that I only a dial-up internet connection, the XP mode file alone is > 500Mb in size. I calculated I would have to tie up the phone line for over a day and I only have one line.
Is there a way to get the files on my work computer, which has a T1 line. However it is running Vista not Windows 7.
I live 40 miles from my home computer to my work computer. and is a real pain to go all this distance.
Microsoft is paranoid as usual. They forget that not everyone has a fast internet connection at home, or can even get one,especially in the country.
I can not fathom that one can not get a CD/DVD that can check if your OS is a real one and not a fake ,along with a copy on the needed files. I have validated my computer at home.

Hello everyone.

I have a problem to install ''Windows Virtual PC '' on my laptop which is running with windows 7 professional 64 bit .
You should know ''Windows XP Mode '' has been installed in the first and When the ''Windows Virtual PC '' is being installed an error message is represented as this '' The update is not applicable on your computer''!!!

The downloaded file of Microsoft Website for Windows Virtual PC is "Windows6.1-KB958559-x64-RefreshPkg" It's size is 16.2 MB.
Now I would like some help how to solve this issue .

Thanks for your help and advice
