A: Sadly, Microsoft killed Outlook Express—its free, fast and simple Windows email program—long before Windows 7 came out. In Vista, it was replaced by something called Windows Mail. Now, there’s no email program at all built into Windows 7, unless a PC maker chooses to include one. But Microsoft offers for download a free product called Windows Live Email that is the latest successor to Outlook Express. You can get it, alone or as part of a suite of free “Essentials” programs that used to be routinely part of Windows, at: windowslive.com/desktop.

I was told that Apple is developing its own version of the Kindle e-book reader. I wanted to purchase a Kindle for Christmas, but now I’m not sure whether I should wait for an Apple version.

A: I have never heard any Apple official say or hint that the company is developing a direct competitor for the Kindle, or is planning to make any dedicated e-book reader. What you may be referring to is that some Web sites have been speculating that the much-rumored forthcoming Apple touch-controlled tablet would be mainly intended to be an e-book reader. I haven’t any evidence of this either.

The iPhone and iPod Touch already can run a free Kindle app from Amazon that allows you to read Kindle e-books on those devices without needing to own a Kindle itself. And Barnes & Noble, which has also announced a dedicated e-reader, has a similar iPhone app. So I assume that any general-purpose Apple tablet would likely be able to run such an app as well and function as an e-reader—along with performing other tasks.

But that’s different than producing a dedicated reader with a screen and controls designed primarily for book reading and a companion electronic book store, something Apple currently lacks. It’s entirely possible Apple is going into the e-book business, but I know of zero hard evidence that this is the case.

Do you have any recommendations about switching an existing 64-bit laptop from Vista to Windows 7? I totally dislike Vista but I don’t know if the switch can be done.

A: Yes, it can, in most cases, unless your PC’s manufacturer for some reason isn’t supporting or recommending the upgrade of your particular model. Just make sure you get the comparable version of Windows 7 (say, 64-bit Windows 7 Home Premium if you are currently using 64-bit Vista Home Premium) so you can do a direct, in-place upgrade that will allow your programs and files to remain in place.

You can also do an in-place upgrade if you opt to move up to the costlier Ultimate version. I would also advise backing up your irreplaceable personal files before you begin the process.

We plan to buy a new computer running the XP version of Windows, not Vista. We are afraid to take the step to the Mac since we are in our 70s, and are just average on the computer. We rely on our children for help when we get into a jam, and they have no experience with a Mac. Would you recommend we venture into Mac land, fear and all?

No. While I believe Apple’s (AAPL) hardware is very good, and the Mac operating system is better than either version of Windows (MSFT), I also believe that average users whose operating system works well for them, and who can buy new hardware that runs the same system, shouldn’t feel pressure to change. That’s especially true when they have a ready source of support.

However, that course of action will become more difficult this summer, when Microsoft plans to stop licensing Windows XP to computer makers for preloading on new machines. That will make Vista the only version of Windows available to new computer buyers. Buying a new Vista PC does require users to learn new techniques and to cope with hardware and software incompatibilities.

I heard that you could still use your AOL email address without paying for the other AOL services, which are no longer used in our household. I am wondering if this is true.

Yes. AOL (TWX) has made its email free. The email service is also now available from a Web site, and no longer requires special AOL software.

I have purchased a new laptop. How do I transfer the songs from the iTunes library on the old laptop into the iTunes library on my new laptop? None of these songs are copy-protected. I created them from my own CDs.

If your setup is typical, I would recommend copying the entire iTunes folder that is found under My Music or Music on a PC, or under Music on a Mac. This folder should contain both a subfolder called “iTunes Music” (which contains the actual song files iTunes manages) and one or more files containing the words “iTunes” and “Library,” which tell the program about your playlists and other details. If your setup is atypical, you may have to copy music files from other folders and have the copy of iTunes on your new machine re-import them.

Another approach is to use an iPod, if it has all your music and playlists on it. There are small utility programs available on the Web that will copy the contents of an iPod, including playlists, into a fresh version of iTunes on another computer. One that I have used successfully is called Music Rescue and is at www.kennettnet.co.uk. It comes in both Windows and Mac versions. But there are others.

Reminder: if you are discarding or giving away the old computer, be sure to deauthorize it from your iTunes Store account before doing so. Just go to the “Store” menu in iTunes and click on “Deauthorize computer…”.
