yes it looks like an '80s Windsor, probably a Super Carrera model. maybe a Carrera Sport. Is there any kind of tubing decal on it? Often these later Windsors were made from Tange tubing (an improvement over the gaspipe of earlier Carrera models) and some frames were even made in Japan, then exported to Mexico for assembly...or so it was rumored. It looks to be a decent mid-grade bike and perfect for a commuter, you could give it a few upgrades, but probably the best thing would be a thorough clean-and-repack of all the bearings. The rack looks to be a Pletscher (or one of the copies) and is cast aluminum.
