Hello, I have a dell inspiron that has the t4300 cpu . I upgraded from windows 7 premiem to windows 7 professional my OS is 64 bit. It cost about a hundred dollars for the upgrade and didn't solve my problem. The only reason i did this is to obtain XP mode so i could run old software that uses a 16 bit installer for a 32 bit os. the problem is my t4300 cpu doesn't support hardware assited virtualization. which processor can i buy to let me use XP mode. Also, would it void my windows 7 if i did this?
