Thanks for the heads up. I'd still be interested to know if anyone rates this site.
I downloaded a 64 bit version of XP which I'd like to use for the larger address space (>3GB RAM and >2TB of HDD space). I know Microsoft offer time limited versions of Win7 \ 8.1 \ 10 for free and I'm using them but re-installing after the trial expiry gets old.
If anyone is interested in the free virtualbox (time limited) images that Microsoft provide they're here:
Suibscribing to MSDN (>500 USD per year) kinda defeates the point of using the free download site, and it doesn't answer my original question. Thanks for the reply anyway.
FYI VMWare and VirtualBox have not abandoned legacy operating systems. The 64 bit XP ISO I downloaded from softlay installed just fine on VB. For a bare tin installation then yes, support is hard to come by as a 64 bit XP OS requires 64 bit XP drivers, and most were written for 32 bit ... but the hardware emulators have no issue with this problem.
I connected to the root of the guest installation via C$ and ran a virus scan from the host. No threats were found. I was also prompted for a licence key.
