What error messages do you get ? ? is your Win ver. legit or not ? ?Windows 10 Release Information
https://technet.microsoft.com/en-us/windows/release-info.aspxwin 10 64 bit home and yes its legit got it from microsoft's official page i dont remember exactly what the error message was but something like 0x800....maybeUpdate Support is a Free PHONE call...all they did was REMOTELY connect my pc to someone and check for updates...i don't see how that is helpful so am asking  you guysIf you TALKED to them they should have fixed the issue...not just checked your updates.

They do have a Hotfix for it...Windows Update Troubleshooternevermind i fixed it turns out i needed to update my win 10 from 1607 BUILD to 1703 and update it to the last version manuallyi did it using the iso file EVERYTHING worked!If they had remoted they would have known which build was installed...
