    Windows Defender multiple issues


    Hi,

    I'm trying to use Windows Defender as my defense solution because I'd like to use the Controlled Folders feature, but am having a few problems.

    System is on 1709 x64 16299.431. No other antivirus, firewall or anything of note running.

    First, the most annoying one: after activating Windows Defender, my system often gets stuck with the "Windows Module Installer Worker" process consuming an entire core worth of processing (plus some disk usage) and it just won't finish what it is doing until a reboot or I kill the process. I understand Windows Defender might be trying to update, but it's getting stuck maybe. This happens more often when waking from sleep/hibernate.
    Note that I have Automatic Updates disabled via GPO, as well as automatic drivers updates disabled. The offending process never shows up arbitrarily like this when I have Defender disabled, and during normal Windows Updates it takes my system just a minute or two to finish its job. I'm confident this problem is related to Windows Defender, and only happens when it is activated.
    This would be a deal-breaker to using Windows Defender for me, so I hope to find a fix.

    Second: I'm trying to protect some entire drives from the root (D:\, E:\, ...) but it doesn't seem to work (as in, protect them from writes). I have an unlisted program I'm using to try saving files, and the writes are successfully blocked if I add specific folders to the list of Protected Folders (e.g. D:\foldername), but have no effect on drive roots.

    Third: I'd very much like to remove some of the default folders from the Protected Folders list. After some searching, I realize this is by design from MS, but it's a nuisance for my use case. Does anyone know of a way to hack them off?


    Alternatively: does anyone know of a simpler solution to block read/write access from unlisted programs to specific folders? I'd rather not use Windows Defender at all, really.

    Oh well, I've given up on Defender again, it's just not worth the hassle and annoyances.
    I've been going for over 8 years without any real-time antivirus and haven't had any problem - a firewall in whitelist mode and some disposable VMs is all I need. Not going to bother fixing what isn't broken.

    Is there a reason why you do not prefer to update to the latest build 1803 ?

    Is there a reason you are not upgrading to the Spring Creator's Update? 17134? With all your updates disabled, you may be missing some crucial fixes, definitely missing some security fixes. It's your decision, of course, but there may be solutions to your issues that you simply cannot get the way you are running.

    I'll wait until it's more stable. I've read reports of problems with Intel SSDs (which I happen to use for boot drive) and high DPC latency issues (which affects my workflow, and was a nightmare for me on 1703 - I actually had to go back to 1607 back then because of it).
    1709 is doing well, will be getting security updates for at least another year and I'm on top of them, so no worries there. Also, there's nothing really new in 1803 that I could use.

    Thanks for the responses!

    Still, if anyone knows of an efficient way to control folder access by application/executable, I'd be glad to try it out.

    Thanks for the info. Yes, there have been/are issues with Intel SSDs. If all is running well, no good reason to try to break it.

    Not really familiar the Defender Folders thing, as I don't use it. Somebody will pop in with an idea.
