I realise drivers will have to be updated to 64 bit versions but can that be done later?

When installing a 64bit OS over a 32bit OS you will have to do a clean installation.
Most, if not all, of your 64bit drivers will be loaded during the installation.

Generally, most 32bit apps will run the same or better on Win7 64bit.

I have not had a 32bit program that I couldn't run on Win7 64bit.
If you have an old 32bit program you might have some issues. You can use compatibility mode.

Make a backup image of Win7 32bit before you install Win7 64bit, just in case for any reason you have problems. You will be able to restore Win7 32bit to exactly what you have today in less that 30 minutes.

Thanks to everyone that offered help. I've been reading on this site for some time now and find it to be the best source of info for Windows 7. I will post my thoughts on the upgrade,can't believe I didn't do this with my initial install,didn't think I had a 64 bit capable processor. Looking forward to doing this. Thanks again!

Your welcome.

If you have the 32bit Win7 setup and want to get the user accounts and personal files you can use Windows Easy Transfer - Transfer To & From Computers

You will still have to install your programs, but this will make it easier.

Thanks for the advice. I have been running 64 bit Linux for quite a while, and have the same opinion. I'd not go back to 32 bit unless I had to. I'll do the same for 7.
Maybe by Windows 10, it will be as good as Ubuntu is today!

Welcome to Seven Forums.

Yes, you can use the same licence key.

One key per installation, 32bit or 64bit, but not both.

That is news to me!!

If that is so, it should be possible to obtain 64bit by download??

When you buy any Windows 7 you will get a 32bit and 64bit DVD and one licence key.
You can install 32bit or 64bit, but the key is only good for one OS.

For the last couple of years MS and most OEMs will send you a 64bit equivalent OS DVD for free or for shipping costs.
