Hello Roger,
Confirm your system clock and Time Zone also the Date set properly, Having
it set incorrectly can cause this type of behavior.
Can you go to Windows Update, select Express (Get high-priority updates),
and apply all offered updates
http://update.microsoft.com
Once that is finished, can you verify the update installs? There are many
pre-requisite files which are needed from windows update and signature update
with windows defender will fail until you have these f!les.
