Question: I use the Windows 10 Mail program to access my Comcast and Gmail accounts. But when I turn on the PC, I get a pop-up message that says “Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client.” But I don’t use Outlook. What should I do? — Ron Benson, Maple Grove, Minn.

Answer: It depends on how you prefer to view email. Let’s look at your choices.

Client software: Windows 10 Mail and Microsoft Outlook are email programs that run on your PC, known as “client software.” You are receiving the warning message because you haven’t designated either Windows 10 Mail or Outlook as your PC’s “default mail client.” (To do that, see

Webmail: Gmail, Yahoo Mail and have popularized the use of “webmail,” which exists only online. You log into a website to read and manage your mail, which is never stored on your PC. If you use webmail, you don’t need Windows 10 Mail or Outlook.

Which method should you choose? If you want to simultaneously use two or more email accounts, it makes sense to consolidate their messages in the Windows 10 Mail program. (To add other email accounts to Windows 10 Mail, see

Question: Debbie O’Bryant of Haines City, Fla., and Larry Forbes of Winter Haven, Fla., asked what they could do to stop a flood of pornographic spam.

Answer: The answer is, not much. But there are some best practices you can follow to minimize the amount of spam you receive. They include:

• Mark objectionable mail as spam. This helps your email provider improve its “spam filter,” which is software that identifies which email to block before it reaches your inbox.

• Never respond to spam, and never, ever click on a link in a spam message.

• Don’t publish your email address online. If you must include your email address on a website, get a second email address and list it instead of your main address.

• You can replace your current email address, but that’s hardly a cure-all. It’s a hassle to inform all your contracts of a new address, and eventually your new email address will get spam, too.

Question: About a month ago, the Edge browser in my Windows 10 PC began getting weird lines in the graphics of all the websites I use. The Google Chrome browser works fine on the same websites. How can I fix Edge? — Ryan Badger, Colorado Springs

Answer: It’s easiest to use the Chrome browser instead of Microsoft Edge. But if you want to use Edge, try downloading the latest software driver for your PC’s video card (aka graphics card), or reinstalling the driver you already have (see If that doesn’t work, it’s possible that the websites you are viewing aren’t compatible with the latest update to the Edge browser.
