I think you mean http://download.cnet.com/windows/
If so, then can you see the small list top left of that page, where it says "Find Software"? If so, then do you have "Mobile apps" ticked, or may be "All software"?
I refined my Download.com searches by just selecting the "Windows" option.
Would that work for you?
don't want to sound like a grumpy old fart, but with so many downloads to sieve through, could this site separate all the stuff into PC or mobiles?
I'm one of the few that don't possess a mobile phone, never mind a tablet or netbook.
It would surely save us all heaps of time tracking downloads .
