Windows 10 update issues. Also can not do a factory reset or any kind of reset

I got this today "Your device is at risk because it’s out of date and missing important security and quality updates. Let’s get you back on track so Windows can run more securely. Select this button to get going"

I ran several command prompts including chkdsk,  got  a repair utility to repair registery... etc,  defragmented and everything  I tried every solution found online and  I still  get this error when useing updates.  I even updated my drivers. I tried everything,  s  I even uninstalled my antivirus and tried it again.   I gave up and tried to do a reset  and also tried to whipe everything and do a reset and can not. really odd. 

Any insight will be appreciated.

Also on the microsoft website I saw a security update dated 09/25/2017 ( today)  and when trying to manually update it said it did not apply to my pc.  I own a Dell Desktop all in 1 64-bit operating system Product ID 00325-95873-11633-AAOEM touchscreen 24 inch all in one
