Error - 0x80040154 Class not registered

[Guest]

Hi,

Afetr installation...I’m trying to perform a definitions update on Windows
Defender (beta2) and I receive the following error, "0x80040154 Class not
registered". Any hints.

I’m using win2K.

Try going in via Windows Update, doing an express scan, and applying all
offered critical updates.

Am I correct that you are seeing this error when updating within the
program?

Hi,

Yes, you’re correct…I see the problem when trying to update within the
program.

I can’t perform a normal Windows Update as my laptop is located on a
corporate LAN (error 0x8ddd0003). Updates are managed differently and not via
internet. Could this be the problem? If this is the case, I should be able to
update the definitions when I’m not located on the corporate LAN?

Any suggestions...

This is probably the case. If your corporate network uses WSUS to
distribute patches, the administrator can make Windows Defender definition
updates available via WSUS.

Whether you can reach Windows Update when not on the corporate network
depends on the care with which your machine has been locked down.

In the end, if Windows Defender isn't sanctioned by corporate policies, you
may need to choose another solution.
