In a closed primary, only voters who are registered with a given political party can vote in that party's primary elections. For example, if you are registered as a Republican, you may only participate in Republican primaries. This system is designed to ensure that party nominees are chosen by the party's members only. In contrast, an open primary would allow any registered voter to participate in any party's primary, regardless of their party affiliation. Therefore, registering as a Republican would not affect your voting options in an open primary state.
