On my SP4 I've made two image backups: one of my 1809 C:\ drive and one of the whole disk including the 'hidden' partitions. (I used Easeus backup) How best to migrate to SP5 - migrate the whole disk with hidden partitions or just my C:\drive? Either way, I'll then do a driver update but I'm wondering whether Microsoft Update also updates the hidden partitions if I choose to restore my entire SP4 disk to SP5. At some point I'll update to 1903 but not yet. Thank you for your advice.
