After updating to Windows Defender 1.1.1347.0 I got the possibility to check
for new definitions.
I clicked the button "Check Now", but got an error:

Windows Defender was unable to complete the update: 0x8001b0100.
No signature was present in the subject.

My definitions version appears to be very old,
vs. 1.0.0.0 created on 25-01-2006.
I want to load new definitions.

An uninstall followed by a re-install did not help.

How to continue?

Please go to Windows Update, and do an express scan and install everything
offered. You should see Windows Defender definitions, and perhaps other
prerequisite code as well.

I got: no high-priority updates availlable.
I expected this, because I try to be always up to date with all my software
(not only Windows), and had checked Windows Update (although set to
automatic).

OK - that moves us forward. Windows Defender definitions are carried by
AutoUpdate/Windows Update. So--with Windows Defender installed--that update
attempt should have at least notified you of available definitions.

I suspect that the answer to this could be found in an excerpt from the
%windir%\windowsupdate.log file--which can be opened in notepad and cut and
pasted back to this thread.

Is this a machine on a corporate or other institutional LAN, or is it a home
machine? If it is a home machine, was it a corporate or institutional
network member in the past?

That looks good. I'm not sure what the error message indicates, but let's
see what the status is
tomorrow. There's no need to leave the machine on if that isn't your
routine--it'll happen at startup, I believe, if the 3 AM windows is missed.

Now, 7.30 UTC, "About Windows Defender" says:
Windows Defender Version: 1.1.1347.0
Engine Version: 1.1.1508.0
Definition Version: 1.14.1637.1

Looks good, but still, when I then click on the button "Check for Updates"
in that same window I still get: unable to complete update: 0x8001b0100.
This does not seem a useful answer...

OK - It seems to me that this must be a generic AutoUpdate problem.

One approach is to do such an attempt to update via Help, About, and then
post the tail end of the log file covering just that attempt and we can look
at it to see whether there's more detail or other specific errors noted.

Does AutoUpdate work for other updates on your system?

I'm sure we covered this before, but you have applied all critical
updates--none hidden? In particular, Windows Installer 3.1 and any updates
to it, as well as Windows Genuine validation (not necessarily the
notification part--although I now recommend that as well)

I never had problems with Automatic Update.
I see the Microsoft Security Bulletins and read several bulletins from
WindowsITPro and am normally very much aware of when an update can be
expected and for what.
I regularly see the Windows Genuine validation and pass it without problems.
My Msiexec has version#; 3.1.4000.1823
I have one small problem: after each boot, Cumulative Security Update for
Internet Explorer for Windows XP (KB916281).

On your test: when attemting to update via Help>About, the get the
well-known message but nothing is appended to the WindowsUpdate.log.
