    Win 8.1 SmartScreen suddenly very active

    After the latest Win81 updates (1/13/14), I'm seeing a lot of SmartScreen activity outside of IE that I never saw before. For example, I'm getting prompts to run programs that I've used for a long time, and it won't let me edit .cmd files.

    Is anyone else seeing this? I hate to turn SmartScreen off completely, but I don't see any SS control other than on/off.

    See if the info on this site can help you sort through it:

    I have mine (SmartScreen) turned off, it's just too annoying to have on...for me.

    Right, I've seen that info. There does not appear to be a way to say, "Seriously, this program is OK to run."

    The thing is, this is new behavior that only started after the last patch Tuesday. I've never been prevented from editing .cmd files before. I've never had warnings about the programs that it's now warning about--they're not new programs, and they're not Internet downloads. I'd like to know what happened.

    I have SmartScreen enabled, and I'm not seeing any unusual activity. I just tried editing a .cmd file, and nothing unusual; right-click and select "Edit", opens in Notepad. Click on "File > Save" and it saves and closes.

    Perhaps a run of sfc /scannow is in order?

    It's certainly possible that a security update is responsible, finding out why will be a little harder.
    If you are also responsible, it's equally possible you can get by without SmartScreen quite easily.

    It's also possible that MS will correct itself in the future, so periodically turning SmartScreen back on to check is also an option.
    As for the specific update, you'll need to look them over carefully to find any reference to SmartScreen handling in each update.
    Microsoft may, or equally plausible, may not provide any mention whatsoever about any SmartScreen tamperings.

    This is a very long shot but, since some of SmartScreen depends on digital certificates, and because certificates depend on correct dates, is your system date still set to 2015?

    CLiNT, yes, I can survive without it. Not worth the effort to track down the patch changes.

    It just bugs me when $@*% happens and I have no explanation.
