Windows Defender Offline on Windows 7 machines DEFINITIONS OUT OF DATE

Windows Defender Offline has stopped recognizing UPDATED Definitions on W7 machines,  Again.

Immediately after updating the Media USB, using the MSSSTOOL, attempts to boot from the USB fail,

indicating that the Definitions are out of date. On both 32bit and 64bit machines.

 This same failure occurred in 2016, on multitudes of W7 machines, between January and July.

Microsoft eventually fixed it by releasing a new version of the MSSSTOOL. 4.9.0221.0  (872kb).

The failure with WDO on W7 machines in 2016 began to occur shortly after problems showed up in

Windows Defender on W10 machines, and was probably the result of fixing the W10 machines.

We may now have the same thing occurring again. After the CREATOR update to W10, it appears they

are having problems with WDO.   And now WDO is broken for W7 machines.

MICROSOFT, if you have modified the configuration of the definitions or the WDO program data in an

effort to repair the problems in W10 machines, please release an updated version of the MSSSTOOL

that will allow W7 machines to accommodate those changes.    Thanks,  Glen

GREAT NEWS !

Windows Defender Offline is working once again on Windows 7 machines.

There has been a change made to the Windows Defender Offline Program.

It no longer updates definitions before running.

In order to take advantage of this FIX, it will be necessary to format your

USB before you run the mssstool. This will ensure that a fresh copy of the

Program is installed on the USB.

Don't know why we were not notified!  I just happened to discover this change,

while examining a WDO problem on Windows 10. There, it is possible track

the operation, using the Event Viewer. I couldn't believe my eyes.

Happy Scanning,  Glen

    [Merged]

    Has support for WDO on Windows 7 machines been discontinued?

    The Microsoft Lifecycle Policy page only describes W10, W8, and W8.1 for Windows Defender.

    For Windows Defender Offline it gives "No Results Found".

    Windows Defender Offline as used on Windows 7 machines, has been unable to recognize UPDATED Definitions

    since May of this year. No interest has been shown by Microsoft in addressing this problem.

    Please define the support status of Windows Defender Offline for Windows 7.

    Thanks,  Glen

    Hi Everyone,

    We are having the same problem at our company. I noticed that the 32, and 64 bit versions will only connect to the internet to update definitions on older ThinkPads. the same USB Sticks will not connect on newer ThinkPads. It is like the WDO USB sticks have drivers for older Network Cards and not newer. 

    Does anyone know how we can manually inject newer drivers to the WDO USB Sticks? We rarely use this tool but like someone above said, when you need it, you really need it.

    Regards,

    Luis.

    Good move Lazy !

    I have been expecting Microsoft to recognize that we have a problem. Maybe they will now,

    after your action.   I am afraid that we may have low priority, however. Looks like they are pretty

    busy killing snakes on W10.

    I also see that the number of views on this thread have increased dramatically. Probably indicates

    that more people are becoming aware of the problem. That may give us more stature.

    Regards,  Glen

    Glen, I reported this problem to Microsoft and requested they check into this issue and fix it.  I first went to Microsoft chat and as soon as I explained the problem with scanning WDO into our computers that have Windows 7, the chat rep sent me to another Microsoft site to report the problem.  Hope this helps. Don't really know what else to do at this point.
