Defender doesn't auto-update

[Guest]

I get a message every 14 days that Windows Defender hasn't updated in at
least 14 days. I click the button to connect and check for updates, and it
never sees any new updates. However, when I connect to Windows Update, I
find an update, install it, and I'm fine for another 14 days.

This does not happen on my home PC, only on my work laptop. I had been
auto-updating after the initial installation, but it has since stopped. Is
there a specific port that Defender goes out to check on, which could have
been blocked?

The only way I was able to get it to work was to go to windowsupdate and
choose custom, install the signature, then restart defender.

Mine says same, then I run an upfate manually which indicates 'successful'
then noted in history that same update is listed everyday since abput 3-29-06
while b4 this date are listed a diferrent update as successfully installed
each day since install. I had thought that updates were installing but not
being reflecxted in the tracking counter...buit apperentl;y not.
My displaty keeps resetting itself to a default setting as well. I change it
and in a little while tt resets.

I had the same problem, defender would do an update then say it was now up to
date but it wasn't even the windows update did not work. I found a work
around, what you need to do is remove the signature registry key from
regedit. To do this I would first uninstall windows defender then open
'regedit', then remove the folder listed below:-

WARNING- backup the registry before you start, if you delete the wrong thing
it could seriously screw your pc.

HKEY_CLASSES_ROOT\Installer\Products\90A2CC5A3D9ECE9429D33078B4DBC4C2

Good Luck
