I have been having this problem: pdfTeX error (font expansion): auto expansion is only possible with scalable fonts even with \usepackage[T1]{fontenc}
My most recent trouble-shooting step is what Ulrike Fischer suggested in How do I invoke cm-super?. Now it seems cm-super is not correctly installed on my PC (I see a .pk rather than a .pfb in the log) even though I do have it in MikTeX Package Manager 
I have refreshed FNDB and updated formats in MikTeX Options (Admin) after installing cm-super.
Googling leads me to this , but I don't know how to follow the advice. Could someone please tell me how to execute M.A. solution "updating pdftex.map by running initexmf --mkmaps" in Windows MikTeX 2.9?
And what else do you think I may have missed?
Thanks a lot.
updmap --verbosefrom the command line (the switch is just to see what happens). – Bernard May 17 '16 at 20:33
