william baugh,   Try reading... Share Files and Printers between Windows 7 and XP This works both ways.     Rick
Hello all. I have a dell inspiron 1545 running xp professional. I have (recently) a dell 660s desktop running windows7. I have a netgear n600 router. the router is wired to the 660s and set to transmit its sid. I have a data connect usb modem on the 1545 (mobile broadband from verizon) I want to setup a wifi or home network between the xp, 7, and whatever computers my sisters kids are currently using to allow internet access. the 7 says only home group running windows 7 are allowed. tell me want I need, and maybe even where I can find it???? must be able to share folders and or files between all computers and printers (1 printer at this time.) thank you.
