I’m replacing five original windows in a damp basement (1927 Portland, Oregon home) with 17″ X 34″ fixed ,milgard vinyl windows. Rough opening is concrete, after removal of old framing, measuring about 20″ X 37″. What considerations should be taken when framing in the windows? What type of wood should be used and how should I fasten it to the concrete opening/foundation?

Skim-coating with joint compound covers texture, renews old drywall and plaster, and leaves smooth surfaces ready to paint.

Treated lumber is now required for contact with concrete or CMUs. Attach with Tappcons or PAD fasteners. The 3" oversize of the rough opening gives you enough room for standard 2x material if the opening is square, level and plumb. I would caulk the joint between the 2x and the concrete as a barrier agianst air/water infiltration.

Good advice, except what are the chances of plumb and square? Only happen if it was a 1927 "fine homebuilder". :-)
I've used 5/4 PT deck boards in that situation. Next time, leave yourself at least 3.5" between rough opening and window size. Fill any gaps with door-window rated expanding foam, then caulk.

Didn't think of 5/4 decking board. Good follow up.
TRIMBUTCHER..... reminds me of the the guy that trimmed my first home. He was called Hatchetman and sons. Signed almost every piece of trim with couple of really good hammer dings.
Just joking, do like the name.

Hey! You making fun of my old man? ;-)
You shoulda seen my first crown moulding job. At least it was MDF...

All really good advice.
If using the expanding window foam...please do remember to caulk it on top or cover the foam with trim or whatever...if left exposed to sunlight, the foam will turn an ugly yellow in days, and soon after start to deteriorate.
