Hi, does anyone else having a problem getting new definition updates for Windows Defender via Windows Update? It says no new updates since 8.7.2019. Manual instalation doesn't seem to work.

hi bzbox:

Windows Defender is usually disabled on my system, but I've also noticed that if I enable Windows Defender and run a manual Windows Update that it will report that no updates are available. I'm not sure when this started but I first noticed that Windows Update was not delivering new virus definition updates for Windows Defender when I tested on 10-Jul-2019 just after the July 2019 Patch Tuesday.

I posted on page 20 of Jody Thorton's MSFN thread Server 2008 Updates on Windows Vista and asked if this had anything to do with recent changes to SHA-2 code signing requirements for Windows Update, but it sounds like some users with Win 8.1 and Win 10 operating systems are having issues with definition updates for their Windows Defender antivirus this month as well - see the 16-Jul-2019 AskWoody.com thread Windows Defender Updates. I don't know if Win 7 SP1 users with the old anti-malware version of Windows Defender (i.e., the same anti-malware version as Vista) are having similar problems.

I can still update my Windows Defender virus definitions manually if I go to https://www.microsoft.com/en-us/wdsi/definitions/, download the latest mpas-fe.exe installer for Win 7 / Vista and save to my desktop, and then right-click the .exe file and select Run as Administrator (Note: double-clicking to start the .exe installer didn't work). I performed a manual update today this way on my 32-bit system, and I didn't see a message telling me the installer had finished running, but my Windows Defender interface now shows I have today's v1.299.282.0 definition set.

I am very pleased to hear that Microsoft has finally cut off definition updates for that worthless placebo! Installing any good antivirus should turn that old piece of junk off; but for years users have been turning it back on, evidently thinking they know better than the makers of their preferred solution. I have argued against using Defender for years, notably in the 3-year-old thread Avast Turns Off Defender. BTW I 'm now using Avast 18.8 on Vista, and I do not know or care whether it still creates Group Policy registry keys to prevent users from turning Defender back on. Hopefully it still does.

Thanks to Imacri, I managed to install Updates manually. Right click, Run as Administrator did the job.
