Windows Update wants to replace WUAUCLT.EXE?

[Mark]

After recently running Windows Update, my firewall
detected that WUAUCLT.EXE was replaced. Is this an MS
approved change, or is the the work of a worm or person
with malicious intent?

Thanks.

Hi,

This is a new version of the Automatic Update control that was published to
the web on Sunday.

Thank you

Eric
