Windows 7: Windows 7 64 bit Vs 32 bit

I was at BB tonight looking at laptops for my daughter. I noticed a large number have 64 bit Windows 7 and not the 32 bit version. Is this going to be an issue since most everything software wise is written for 32 bit machines? Does this mean I will have to look for software written for 64 bit or Windows 7 only?

Thanks

I would suggest, as you are buying a new computer, buy the 64-bit one.

64-bit is quickly becoming the new standard, and for most programs there will be no problem running them on the computer.

The only problems would be if there is a need for a 64-bit driver, which most consumer applications don't need, or have easily available, especially if it has been made in the last four years or so.

Almost all x86 (32-bit) software will run on x64 (64-bit). You may find some old software that doesn't but not that much. If you must have a specific program then I would recommend Googling for compatibility issues with Windows 7 x64. Anything new should run just fine and a lot the older stuff has been upgraded if it is still supported. If you worry about old software consider buying the Professional version on Windows 7 so you can get XP mode to run the old stuff.

Get the x64...It just works and doesn't suffer from the x86 limitations. I speak only for myself but I'm x64 and there's no going back.

Also, if there is a need for a legacy program (XP or earlier, or 32 bit) you can download Virtualbox (freeware), and setup XP in VB for running legacy programs.

OK, cool, 64 bit it is. Now on my desktop I installed the 32 bit version not knowing any better. 7 came with the 32 and 64 bit versions. What do I need to do to upgrade from 32bit to 64bit, can I just pop in the 64bit disk and do a re-install?


Thanks

No, to upgrade from 32-bit to 64-bit you have to do a clean installation. That means you'll need to back up any files you want to save, then do the install, and during the install, tell it to wipe the hard drive.

Clean Install Windows 7

Thanks, not worth it for the small gain.
