Q: I am using Microsoft Outlook as my email client. My friends tell me my emails to them include an attachment called Winmail.dat. How do I keep my Outlook from sending this worthless attachment?

A: This problem occurs when the software that the recipient is using is not sophisticated enough to support the message features that are included in your Outlook-created message. To keep Outlook from sending the Winmail.dat file, you need to add the DisableTNEF entry to your computer’s Registry. To do this, follow these steps:

  • Exit Outlook.
  • In Windows 7, click the Start button, type regedit in the Search programs and files box, and then press Enter.
  • If you are prompted for an administrator password or for confirmation, type the password or provide confirmation.
  • Locate and then select the following registry subkey: HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Preferences (note that the 14.0 may be a different number on your machine).
  • On the Edit menu, point to New and then click DWORD Value.
  • Type DisableTNEF (there are no spaces in this) and then press Enter.
  • Right-click DisableTNEF and then click Modify.
  • In the Value data box, type 1 and then click OK.
  • Exit the Registry Editor.
  • Restart your computer.

Q. I have a Windows 7 system. I am receiving emails that have photos attached. However, the photos are coming in sideways. How do I rotate them for a better view before I forward the photo on to others?

A. Here’s what you can do:

  • Go to your email program’s inbox.
  • Open the email that contains the photo but do not open the attached photo file.
  • Right-mouse click on the attached file and choose “Save as…” (or words to that effect).
  • Save the file with a meaningful name in a folder you will remember (such as the My Pictures folder).
  • Exit your email client and close all open windows.
  • Click your Start button, then click Computer to open Windows Explorer.
  • Navigate to where you saved that file (My Pictures?).
  • Double-click the file. Windows Photo Viewer should open the file (unless you have changed the default program that opens your pictures).
  • In Windows Photo Viewer, click the rotate buttons at the bottom of the screen until the picture appears correctly.
  • Click the File menu and choose Make a Copy.
  • Save the picture with a new name to save its new orientation.
  • Now you have a file that you can attach to a new email to send to friends.
