Should I be running Windows in 32 or 64 bit?

Episode 1167 (46:40)

Sean from Burbank, CA

Sean bought a used HP Touchsmart computer running Windows 7. He's planning to restore it and wants to know if he should change the OS to 32 bit or keep it at 64 bit. Leo says it doesn't make any difference except for the amount of RAM he has. If it has more than 4GB, then he should keep 64 bit. If not, then go for 32 bit.

If he runs into issues with Windows Genuine Advantage, he may need to contact Microsoft. Is 64 bit faster? Leo says not always, in fact, in some cases it can even be slower. But with a massive amount of data, using 64 bit is faster.
