I just a question if i can run Windows XP Mode on Windows 7.. Im using an Acer 4736 Laptop with T6600/320HDD/4GBDDR3/INSYDE BIOS THANKS.
You could check if your BIOS can support a Penryn-R0-3072 CPU (P8600,P8700,P8800 - they have IVT), or a Penryn C0 (T9300,T9500) and consider upgrading.
Upgrading as Servi mentioned is a good but expensive option. If you don't want to go that route than get VirtualBox or VMWare Workstation and install a virtualized XP there.
as mentionned in my post above... the difference is that with hardware vt support, you won't even notice your running virtualisation, because vt adds a subroutine on your cpu, making it being executed instantanious.
