You can't.

If on a Mac, and you elected to save such to your Keychain, you can recover it from your Keychain. Otherwise, you can't.

While you can continue to sync/backup, if you can't remember it & want to remove it, you'll have to delete your existing backups & restore the phone as a new device. Your data will be unrecoverable.

No.

Your data will be unrecoverable.

Copied from my initial post:

"If on a Mac, and you elected to save such to your Keychain, you can recover it from your Keychain."

You would have had to do that when first electing to encrypt..too late now.

Has nothing to do with your Apple ID.

No.  I am sad to say that unless you can remember the password for the encrypted backup, you will be unable to recover that content and information. The password is not stored on any server or in connection to an apple id.  It doesn't transfer to other devices. It stays with that backup.

As already provided:

Again:

You need to delete all of your existing backups: iTunes>Preferences(under the edit menu in Windows)>Devices...highlight & delete here.

Then, restore your phone as a "NEW" device.

That's the only way to fix this.

Are you trying to restore from a backup?  Or, are you trying to backup and then restore?  If you are trying to backup in iTunes on the computer it gives you the option to uncheck the encryption.

Only if you know the existing encrypted passcode, which the OP does not.

On the windows computer, he will not be able to.  However, on the new mac, he will be since he has never created a backup to that computer.  He will not be able to unecrypt the original backup but he can stop it from happening in the future on the new Mac.

Sorry, but you are wrong.

The directions I gave the OP are the only way out of this mess.
