Miktex + LyX. Pixellated font?

My Miktex (2.7) install came without the "Computer Modern" vector font, and PDFs generated by LyX came with an awful bitmap version. There were two reasonably easy fixes:

1. Go to Document->Settings...->Fonts and choose the Latin Modern variant for the three font families.


2. Open the Miktex package manager, find the cm-super package and install it.

Both worked for me, but I stuck with the second option rather than make global changes to LyX default document settings.
