If iCloud was installed for the current user only, not all users, the keys under HKEY_LOCAL_MACHINE may be under the current user's Security ID keys (S-1-5-21*).

This will "break" iCloud (which is already broken) and it will ask you to do a repair when you re-open the iCloud control panel.

If it keeps getting disabled, see iCloud Doesn't Sync for a solution. Once it's fixed, do not delete it again! If iCloud is not syncing, verify the add-in is enabled.
