All my knowledge of Microsoft Office programs & different versions of Windows (Geez, I even remembers the years of using Windows 3.1 back in late 1980's) has been from learning on my own or informally asking others. Never taken a course. Powerpoint I first learned from a book that I bought for the library that I ran.

Excel-really basic. My mathematical skills really aren't comfortable embedding sophisticate algebraic forumulae to do automatic stuff in certain cells. And Word knowledge has been alot of survival experimentation.

Instead my computer literacy skills has been focused on other software OUTSIDE of Microsoft Office, where my job focused heavily on acquiring detailed knowledge...to automate a whole department and other software to teach others how to do online research. For this type of non-Microsoft software, I have taken some in-depth courses.

Windows now intimidates me....it takes up so much memory. And when something goes wrong...it's hard to know where to start to troubleshoot. So different from 20 years ago when computer software was simpler.
