Does any PC manufacturer offer an option to order a Windows (MSFT) PC without any extra software preinstalled?

Dell’s XPS models can be ordered without most preloaded third-party software if you are very careful about clicking all the “no” options when ordering online. But you still are likely to find yourself with Dell’s (DELL) own sometimes annoying networking software.

I have two Windows machines, one for work and one for home. Both use Outlook for email. How can I best transfer many emails from the machine at work to the one at home and still be able to read them in Outlook — without forwarding them all?

Outlook has an “Import and Export” function that will allow you to export any of your email folders to, say, a transferable medium such as an external hard disk or flash drive. You can then take this removable medium to the home computer, plug it in, fire up Outlook, and then import the folder you had exported earlier at work. You can find these import and export functions under Outlook’s File menu.

Can Internet Explorer and Firefox 3.0 coexist on the same computer?

Yes. In fact, you can have 2, 3, or 4 different Web browsers installed on the same personal computer, whether Windows or Mac (AAPL). You can even run different browsers simultaneously. For instance, as I type this, I am running IE 7, Firefox 3.0 and Safari 3.0 on the same computer at the same time.

The only slight hassle is that you will have to decide which to designate as the default browser, the one that launches when, say, you click on a link in an email.

I couldn’t find any columns on products you recommend for monitoring kids’ Web access and installing parental controls. I recently purchased a new computer for my 9-year-old daughter. I want to make sure she can only access specific Web sites and I want to protect her from inappropriate spam and chatting.

If you have a computer running one of the newer versions of Windows or the Macintosh operating system, I recommend using the extensive parental controls that are now built right into those operating systems. While you can never underestimate the ingenuity of computer-savvy kids, these built-in controls, if properly used, are generally harder to evade than the ones provided by third-party software.

I did recently review these built-in parental controls, which appear in Windows Vista, and in the Tiger and Leopard editions of the Mac’s OS X operating system. You can find that column at: ptech.allthingsd.com/20070614.

I want to switch to a Mac, but my life is on Microsoft Outlook, which is only available on Windows. Is there a simple way to convert all of this data to programs on the Mac?

There is a $10 program that performs this task. It’s called O2M (Outlook to Mac) and is from a company called Little Machines. It can be downloaded at littlemachines.com, where you also will find details about the Mac programs with which it works. This is a Windows program, which transfers your Outlook data into files you copy to your Mac. You then manually import these files into your Mac programs.

According to the company, the program exports Outlook email, email attachments, contacts and calendar appointments and allows you to import this data into Apple’s built-in email, address book and calendar programs, as well as into Microsoft Entourage, and other third-party programs.

Another approach is to install Windows on your Mac, and keep running Outlook. If you do this using the Parallels or Fusion virtualization programs ($80 each, plus the cost of Windows,) you can run Outlook simultaneously with your Mac programs.

Does the new version of Microsoft Office for the Mac work on pre-Intel Mac models?

Microsoft says it does, though I didn’t test it on one of these older machines. According to Microsoft, the new Office 2008 runs on any Mac “with an Intel, PowerPC G5, or PowerPC G4 (500 MHz or faster) processor.” However, you also need a relatively recent version of the Mac operating system, either the new Leopard edition, or the latest update (called 10.4.9) of the Tiger edition.

My IT department will not turn on the feature in our servers that would allow me to receive corporate email on my iPhone. This has forced me to revert back to my BlackBerry Pearl. Can I transfer my iTunes music to my Pearl?

It depends on what you mean by “iTunes music.” If you mean music you bought from the iTunes store in protected format — which describes most of the store’s catalog — the Pearl can’t play it, unless you go through a laborious multistep process to convert it to unprotected files. If you mean unprotected music that is managed by the iTunes program on your PC, the Pearl can handle it as long as it is in open formats supported by the Pearl, including the MP3 or open AAC formats.

To get these files into your Pearl, simply use the music-transfer software that came with the Pearl to copy the songs from your computer’s hard disk to either the Pearl’s internal memory or to a flash memory card you may have in your Pearl.

I recently purchased a new iMac with the Leopard operating system, and have installed Windows Vista on it as well, using Leopard’s Boot Camp feature, so the Mac can boot into either OS. I would like both of those operating systems to share an external hard drive so I can back up my files. Is it possible to do that?

Yes, provided you follow one of two scenarios. The first would be to format the external drive as a Windows drive, but be careful to use the Windows format called “FAT32,” not the one called NTFS. Out of the box, Macs can see all Windows drives and can read from them all. But they can only save files to Windows drives that use the FAT32 system for organizing files. The downside of this is that the FAT32 system only allows files of up to 4 gigabytes each.

The other scenario would be to use a Mac-formatted external drive, which doesn’t have that limitation. Of course the Mac operating system can handle such drives perfectly, but Windows can’t even see them. However, in your Vista setup, you can install a third-party Windows program called MacDrive 7, which allows Windows to both read from, and write to, Mac-formatted drives. I have tested it successfully with Vista under Boot Camp on an iMac. The $50 program can be downloaded from mediafour.com.

The hard disk on my new Sony VAIO laptop is filling up fast. It is trying to get me to watch a lot of movie trailers. Is all that video stored in my machine somewhere and if so can I dump some of it out?

If your Sony laptop is like mine, not only are the unwanted movie trailers pre-loaded on your hard disk, but so are the entire movies, which Sony actually charges you to watch. In my case, these files took up over 4 gigabytes of precious disk space. This is a particularly outrageous example of what I call “craplets,” unwanted trial software that litters new Windows desktops. You can delete these files and reclaim all that disk space without any harm to your computer.

Apple makes beautiful hardware, and, in my experience, it runs Windows quite well. In fact, the mouse and keyboard problems you cite are easily overcome, since you can plug almost any USB keyboard and mouse made for Windows into a Mac and they will work fine, right-mouse button and all.

However, what makes a Mac a Mac is primarily Apple’s OS X operating system, and the software Apple bundles with it, the iLife suite. If you don’t intend to use that, I don’t see much point in buying an Apple computer. You won’t get the advantage of the Mac’s lack of viruses and spyware, which stem from the operating system, not the hardware. And you can buy a Windows computer for less than the least expensive Mac.

In my view, the main value of the Mac’s ability to run Windows is that it allows Apple owners to use the few Windows programs they require or prefer that lack Mac equivalents, while primarily running the Mac operating system and programs designed for it.

How can one send an email to a group of people without all of their individual email addresses showing?

The most common method is to put your own email address in the “To” field and the names of all the recipients in the “Bcc” field, which is designed to be invisible. There’s always a danger someone quickly scanning just headers will decide not to read the email, since it isn’t addressed to her, but most email veterans understand the technique.

Is there a way to regain the traditional drop-down menus and other interface items in the new, redesigned Microsoft Office 2007?

There is at least one third-party add-in program designed to do this, but I haven’t tested it. It’s called Classic Menu for Office 2007, and can be found at www.addintools.com.
