If your computer is 64bit capable then if you buy, say, Windows 7 and it has BOTH 32 bit and 64 bit versions on it then yes it's free. You would have to contact Microsoft to see if you would have to pay to upgrade from a 32bit version W7 to a 64bit version.You have to find out if the computer is capable of supporting a 64bit OS. if it isn't then you'll have to buy a new computer or replace the mother board and you would still have to have a 64bit OS to use it to it's full potential.Apple's MacOS and computers from 2006 up are already 64 bit capable.
There is not. And that is because 64bit can run 32bit, but 32bit has problems running 64bit.
64bit
Absolutely !
64bit
64bit processors have most registers specially the integer registers as 64bit. It can handle 64bit wide internal and external data. All internal and external buses may or may not be 64bit wide. - Neeraj Sharma
Yes, but it doesn't work wit 64bit browers like the IE 64bit....
The size of the accumulator is the same,means 64bit.
No
Over the years I have found that computers with 64bit dual or quad core CPU's and a 64bit operating system is best.
No, not unless all of the following .Confirm that the computer's processor and motherboard are both 64bit. All 64bit Windows Operating systems will only work on computers that have both 64bit processor and 64bit motherboard architectures.Confirm the computer has no less then the other minimum hardware requirements (Processor Speed, Ram memory, Hard Drive memory, etc.) for the Windows 7 64bit version you want to install.Windows XP 32bit must be removed/deleted before doing a clean install of Windows 7 64bit on the hard drive.
The difference between 32bit windows and 64bit windows is the resolution of the image and the higher the bit the better the image.
