how do I find a login window for my itunes account. I haven't opened it in a long time.

Hey there suraza,

You'll want to follow along with the steps below to help get signed in with your Apple ID in iTunes on your PC:

Set up and view an iTunes Store account on PC

To buy items in the iTunes Store, you need an Apple ID. If you don’t have one, you can set one up using iTunes. You already have an Apple ID if you joined Apple Music, have an iCloud account, or purchased items from the Apple website.

Sign in to the iTunes Store

When you have an Apple ID, you can sign in to the iTunes Store to buy music and video, view or change your account information, and see your purchase history.

1. In the iTunes app  on your PC, choose Account > Sign In.

2. Do one of the following:

* Sign in with your Apple ID: Enter your Apple ID and password, then click Next.

* Create an Apple ID: Click Create New Apple ID and follow the onscreen instructions.

To sign out, choose Account > Sign Out.

See the Apple Support articles Sign in with your Apple ID and Two-factor authentication for Apple ID.
