The summary so far:

Issue relates to build 10240 Update server Itself,I hope MS corrects it soon.

Immediate resolution:

• Pro Users: Click on Defer Upgrades-that would change your Windows update server and the problem would be resolved.However,upgrades would be postponed.Another Alternate Download version 1511 through media creation Tool and perform an In-place upgrade.This would make sure you are on the latest build of windows 10 and you would receive the Aniversary update due July this year.
• Home users(Home+Home SL):No defer upgrades option,the only thing is to download version 1511 through media creation tool.
