I have Windows 8.1 and use Outlook for my email. How do I get Outlook to complete email addresses so I don’t have to type the whole address each time? In XP I only had to type in the first few letters and it completed the rest of the address which saves much time.
Kathleen, you’ll need to turn on autocomplete in Outlook. Here’s how to do it. Open up Outlook and click the file tab.

The select Options

When the Outlook Options window opens, select Mail from the list on the left.

Scroll down to Send Messages.

Tick the box next to Use Auto-Complete and hit okay.

Now Outlook should offer autocomplete options when you start typing addresses.
