If you create a soft link to the Program Files (x86) directory and make the name without spaces or parentheses, then you can use that directory in conjunction with scp.
On Cygwin (10.10.10.10)
cd c:
ln -s "Program Files (x86)" PF86
On Linux (home computer that you're running scp on)
scp root@10.10.10.10:/cygdrive/c/PF86/myfile.xml .
And it works
