Tried to update Windows 10 Home 64 bit from the cumulative catalog file.
Got an error that my version could not be updated. Could somebody that has

What does your "winver" command report ?

Run it from Start : Run or enter it in a
Command Prompt or Powershell window.

Then post the number.

A "Cumulative" would be a Windows Update security update,
which will raise the patch number "y" on the x.y
format of Winver. The "x" corresponds to the OS release.

If the "x" value is old enough, it's out of support.
And downloading a current DVD image and running the
Setup.exe on it, will get you the current release.
