Ivan noted that on his PC the text he writes is frequently "marred" by squiggly underlines in blue. Right-clicking gives him options of Ignore Once, Ignore Rule, or Replace Direct Formatting with Style Normal. Ivan wants to turn off the blue squiggly underlines and is wondering how to do it.
Word likes squiggly underlines and has used them differently in different versions of Word. The most common squiggly underline is red, which marks a potential spelling error. In some versions of Word you'll see green squiggly underlines, which indicate a potential grammar error. The blue squiggly underlines were originally used to mark formatting inconsistencies, which is why Ivan saw the options he noted—particularly "Replace Direct Formatting with Style Normal"—when he right-clicked the blue-squiggly-underlined word or phrase.
You can turn off this marking of formatting inconsistencies by making a configuration change in Word:

In some versions of Word, though, blue squiggly underlines are also used to mark grammar errors. (Yes, Microsoft has changed this—in some versions it was green, in some versions blue. Go figure!). If you turn off the setting noted above and you still have blue squiggly underlines, then follow these steps:

That should do it; your blue squiggly underlines should be gone.
