How do I change my Windows Vista operating system from 32-bit to 64-bit?

I had the choice between initializing 32-bit and 64-bit when I first turned on my computer after buying it. But I didn't know which one to choose, so I chose 32-bit. After researching, I realized it would have been better to choose 64-bit.

You'll have to reinstall. You should have the ability to make a Vista DVD (or two) from where your manufacturer put it (look in accessories) and then reinstall. You might be able to get away with an %26quot;upgrade%26quot;. Either way, there is not a magic switch.

If you had the choice, then I imagine that your system is 64-bit compatible. Nice. Just reinstall the OS and this time select the 64-bit option.



Only problem with 64-bit is that there aren't a lot of applications that have made it that far yet. Maybe some games, designing software... that sort of high level stuff, but day to day apps... not so many.



Have fun with it... Good Luck!
