Think you just need to be patient - it can take hours. However, you say last updated in July - there have been dozens of updates since then. Are you set to install automatically or manually? If the latter, have you checked before?
gordon ...just an up date the readiness tool installed very quickly then during the install instead of 15 mins it was stuck on 90% for about half an hour or more eventully completed, ran updates again and its going through installing 27 updates [hoping w10 will be there]. thanks for the advice had been stuck with this for ages.
