DebraK1 - have you found anything that has worked yet? I've been troubleshooting this for two weeks and still have not found the solution. My system indicates there is no corruption but I can not get past "your device is missing important security & quality fixes". I can't identify what security & quality fixes are missing and I can't get Windows 10 to do an update.
Hi Sis48,
Let us look into this.
Please try installing the latest feature update manually and let us know.
The fastest way to get the upgrade is through the Media creation tool or ISO file.
Please download the Media Creation Tool and select "Upgrade this PC now".

If the update fails, let us know the error code, and run the Setupdiag tool. Post the outcome of the same.
We may need some logs depending on what the outcome is.
