Windows Defender on Win8 - Updating Defs

It might be prudent to create a Scheduled Task for Defender on Win8 if WU is not configured to AU (Autoupdate) since
a. Defender doesn't have a user configurable setting to run a scheduled scan but it does perform a quick scan daily using current
installed defs
b. Defender doesn't update itself
c. Defender doesn't indicate an an out-of date condition until the 7th day after the last def creation date and only if the
Defender UI is opened by the user (since Defender does not provide a Notification Area icon)
d. Win8 Action Center does perform a check and notify the user but only if the Action Center Security settings are configured to
show messages for the respective item (Virus Protection, Spyware) and the defs are out-of-date using the same criteria as (c).
e. Defender, if finding the presence of an intrusion, will only update defs if new def signatures apply to the detected intrusion.
If more current defs are available they will be downloaded and applied to mitigate the intrusion.

The Win8 Scheduled task to check for new defs and update from the Malware Protection Center is:

C:\program files\windows defender\mpcmdrun.exe –SignatureUpdate –MMPC

Fyi...you can also run the above from a command prompt.


i.e. If you understand the above you should easily ascertain that Defender on Win8 (as-is currently released) does not operate the
same as MSE on earlier o/s (XP, Vista, Win7)

For all the reasons you've listed, I've installed MSE on my Win8 laptop.

If you did then its' likely an earlier and a beta version of MSE was installed on Win8
- e.g. MSE v4.0.1512 since Win8 supposedly rejects production versions.

Oh. I'll check it out, but I think MSE only shows spyware and virus
definition versions.

Thanks for the heads up.
