She/he to refer a user [duplicate]

Can the feminine pronouns be gender-neutral?
Is there a correct gender-neutral, singular pronoun (“his” versus “her” versus “their”)?

Programmer here. I am confused with the usage of the term "She/he" when referring a prementioned and undefined user. Below is a sentence found from MSDN magazine:

"When the user decides to create a new customer, she must fill in the data entry form in Figure 2."

I myself use the term "She/he" is this context, since without mentioning both can be regarded as gender discrimination, and placing 'she' before 'he' is respecting the ladies.

So, can I just use 'She' in this context, that will save some typing.

Most people, until recently, preferred the use of masculine pronoun. But with the rise of female writers, feminist literatures, and feminist movements, the trend has changed dramatically, with many writers inclined toward the use of feminine gender.

That said, the use of he/she is a bit awkward and is better avoided. From the other two, it doesn't matter which one to choose as long as you are consistent.

I have observed a tendency in technical communications to alternate between using 'she' and 'he'. It is even suggested (though not necessarily recommended) in this article and this other one as a solution to "The Pronoun Problem":

For example, always use he/him/his in odd numbered chapters, and always use she/her/hers in even numbered chapters. This strategy does promote balance and has sometimes been used to good effect in textbooks, but it doesn't solve the real problem of distracting the reader.

Personally I find it very distracting, and also a bit silly.

This question has some other answers about addressing "The Pronoun Problem" with other gender-neutral alternatives.
