Here it goes, I've also got a Tosh Laptop here are the specs:
Intel Core 2 Duo, 2 Gigs of Ram, 170GB Hard Disk etc..
So I bought it with Windows XP Media Center with a free Upgrade to Windows Vista Home Premium 32 Bit.
Now to me Toshiba had this wrong and were being lazy, a 32Bit Operating System on a 64Bit processor?
So I went out and bought the 64BIT home premium and its amazing, I have no problems at all.
I wouldn't change it for anything
all my software runs fine, I really can't complain about one single thing. I even have managed to get all the drivers with a little work.
