Windows Defender Offline definitions out of date

Windows 7 64 Bit.  I have been using Windows Defender Offline on a USB thumb drive (4 GB, uses less than 1 GB) for years without problem.  Last week updating Windows Defender Offline definitions to an already working USB thumb drive seemed to install correctly.  When I boot to the USB thumb drive the program boots and runs but I get the message the "definitions out of date", and it will not scan the computer.  I tried formatting USB thumb drive and then installing the whole Windows Defender Offline with definitions instead of just updating the definitions to the already working USB thumb drive.  Everything went correctly, the size of the download appeared to be correct.  I booted to the USB thumb drive and still got the message "definitions out of date".  Since the Windows Defender Offline program started offline, and was installed onto a completely formatted USB thumb drive, it must have downloaded and installed correctly but the definitions are still "out of date".  Are the definitions being updated by Microsoft or has the program been discontinued?

Not sure that matters at this point, the messages appear to be pointing to 2 unrelated failure points.

I have an update.

We have identified the problem and are working on a new Windows Defender Offline release.

    It appears the ability to download the tool and create bootable media has now been removed. I don't see it anyway-- (https://support.microsoft.com/en-us/help/17466/windows-defender-offline-help-protect-my-pc)

    Hi Chuck,

    To help you with your concern, here is the Download Tool link: Windows USB/DVD Download Tool.

    Feel free to post more inquiries.

    I followed the link provided, but evidently, it has nothing to do with downloading Windows Defender; rather, it appears to be for downloading the entire Windows OS.

    Found what may be BETA copy of the MSSSTOOLs at these locations.

    Glen,

    I don't know where you found those BETA copies that you linked to, but the standard WDO download location is now offering working files again: Help protect my PC with Windows Defender Offline

    I just tried running it on a Windows 7 machine and it worked the way it was supposed to; WDO no longer produces the "definitions out of date" error.

    Dexter

    Evidently, download is no longer offered on the page you linked to.

    Since WDO has not been working properly for several months why not try one of these?

    I tried Kaspersky Rescue Disk on a system with dual drives configured as RAID 1. It evidently knocked the volume offline and the system would no longer boot. I thought I had completely lost the contents of both drives.

    Interestingly, I disconnected one of the drives, and the system booted. I then shut down, reconnected the second drive, the system booted, and I was able to get RAID 1 functioning normally again.
