Three of my PCs updated from 1903 to 1909 to 2004 then 20H2 with minimal frustration. Two were old eMachines (2010 vintage) and my two year old Dell laptop. However, my wife's Dell laptop, a year older than mine, is stuck on 1909 and will not update to 2004 no matter what method I use. You know the drill. I assume it's the black cloud over her PC, but it makes no sense to waste 5 or 6 hours so at the last minute it stops and says it will not update. I have read reams of material of others having the same problem with no apparent fixes. Anyone else having such trouble?
