64 bit compatibility

Planning on installing 64 bit version on a new drive and make current drive mostly backup now. Will I still be able to run software from the old drive that is 32 bit (such as Office, WOW)? Thank you in advance for your expert opinions

I'm no expert but I have done this quite a number of times....

64 bit versions of Windows can run 32 bit applications. If you are going to load a new OS then you will need to re-install the applications and then move the old data over to your reinstalled applications. Be certain to have your old data backed up on a drive separate from the C drive where your OS is to be loaded, like on an external drive, regular hard drive, USB flash drive or DVD. The really safe thing to do is to have your data backed up to two drives before installing your new OS. You never want to have only one copy of your data in existence.

So the applications would have to be moved to that drive then? I won't be able to just run them from the existing drive once I install 64 bit Win 7 on new primary drive?

Nope, sorry. The OS that you are using has to be the same OS that installed the applications. You can though install applications to a drive separate from where your OS is installed, if that is any consolation. Also, there is no upgrading from a 32 bit OS to a 64 bit OS.

In your situation, the OS has to be installed from scratch...and then the apps installed. I know, it is a bit of a PITA.

The good news is that a fresh OS installation quite often makes your computer feel snappier than before.

Ok thought so. Just wanted to make sure. Good to hear as making it "snappier" is my goal without upgrading everything right now. Unfortunately hard drive prices ATM are screwing me.
Thanks again

What OS are you running now, and what are your computer's specs?

Until you've spent several hours downloading the endless updates for Windows, then it's as sluggish as before.

Not necessarily. I have experienced a faster computer by re-installing the OS plenty of times. Also, it does not normally take me more than about 3-4 hours to re-install, including all the updates.

Hi

One exception is Wow.
You can run Wow on anything without reinstalling it.

I have a friend who runs a copy of my installation on his external USB hard drive and I've copied mine from computer to computer and from 32 to 64 bit with no problems.

Mike
