The daily security updates (sometimes 6 or more a day). They do not automatically update but put them in manually by checking for updates. The problem being that they come in every 4-6 hours. If you miss the timing it will update to the next one in the line and skip the one you missed. Meaning you only get the most recent one in line. I guess the question is if I miss one or two will the next one make up for it. I can see on Windows 10 updates which ones were to be updated and missed. I always have the latest but ones in-between are lacking from my Update History. 'Windows Security seems to have the latest one but there is no where to check what came before that one. Am I missing something or does it matter if I have the last Intelligent Security update? There is no way to figure out when they are ready other then go to Windows 10 updates and check the list. One would have to spend an hour a day to keep track every so often. I also want to say that I have run the Windows updater Troubleshooter. I does not find a problem. sfc/scannow has found other problems but not in updates. DISM also.

    Windows 10 will continue support until October 14, 2025, at which point all support for consumer systems will end.

    Though in the past Microsoft has provided extended support options to enterprise business and possibly a few other major organizations like governments, I've never seen any offerings of these option for anyone else, including individuals of any sort.

    If your own systems won't support upgrade to Windows 11, then it's best to start planning for what you'll do when this support expires in about a year and a half. I personally expect to buy something new around the time the expiration occurs, since I'll want whatever new system I choose to have the longest useful life possible.

    I will not, however, ever overbuy a system again, since the way these systems are supported now means I may need to replace it again in several years just like this one. I had only bought this Microsoft Surface Go tablet in early 2019 as I recall, but at a discounted cost around $450 or maybe less, which is far cheaper than anything I got in the past for something that has worked well for 5 years and will be over 6 years old when support ends.

    Thanks again for your quick help in this matter,

    Once I run: set-mppreference -SignatureUpdateInterval 5

    • set-mppreference -SignatureScheduleDay 0

    Under run as administrator. Do I need to change any other files on HD? To change back just use your posted answer on previous thread. Sounds well planned out.

    Thanks,

    Hi Alan,

    KB2267602 is the KB number for Defender Security intelligence updates. And yes, it's cumulative.

    Please note that when the Defender scheduled task ("Windows Defender Update" - periodic signature update task) or the Windows Security app updates the definitions, they won't be shown on the Windows Update history page. But every update attempt is logged into the file "c:\windows\temp\MpSigStub.log".

    You can check the security intelligence version by opening Windows Security → Virus and threat protection → Check for updates. You can update the definitions from there, but it won't be reflected on the WU history page.

    And here is the security intelligence change log released by Microsoft.

    I want to thank you for such a quick answer to this. If this means I can just update it a 2-3 times a day by manual update and not worry about missing a few in-between since one will be cumulative I am fine with that. I have never used power shell. Is this cumulative KB2267602 since I have seen no other Security intelligence updates. No matter. You helped to find the answer I needed.

    Thanks,

    Alan Sheriff

    Hi Alan,

    The Defender updates are cumulative. By default, Windows Update updates it once per day, although MMPC releases a new set of definitions every 3-4 hours. Other than Windows Update, the Defender signatures are updated by a built-in Defender Update Scheduled task (which is triggered when the system is idle).

    To increase the signature update frequency, you can use admin PowerShell and run the following commands:

    • set-mppreference -SignatureUpdateInterval 5
    • set-mppreference -SignatureScheduleDay 0

    (the above command forces Defender to update its definitions once every 5 hours.)

    To revert to the Windows default setting, run:

    • set-mppreference -SignatureUpdateInterval 0
    • set-mppreference -SignatureScheduleDay 8
