Windows 10 Applocker Bug in 1511?! RRS feed

  • Question

  • Windows 10 enterprise 1511 from November.

    If I activate applocker with dll files, audit only or enforce rules doesn’t matter, I got BSOD. Same result on domain computer or standalone.


    If I replace the appid.sys from the first release of windows 10 everything works.

    Appid.sys 10.0.10240.1638 2015-07-10 Works

    Appid.sys 10.0.10586.0 2015-10-30 Get BSOD!

  • I'm seeing the same behaviour....

    DaRT disk saved affected systems by allowing easy edit of registry to set the AppID service start-up to disabled.

    Thanks for the info about appid.sys being at fault.

  • Please can someone from MS advise when this will be patched / fixed.

    I am concerned that since KB release notes no longer include technical details that customers won't know when the issue is resolved short of testing against every update that is released.

    AppLocker not working is preventing Windows 10 being deployed for customers who operate in highly secured environments.

  • Another few weeks has passed and nothing from MS yet. Is there any update PLEASE?

  • Strange that no one from MS can comment on this bug, or just say anything...

    It seems to be a new version of appid.sys in the latest windows 10 insider preview build 11082, but I haven’t had time to test it yet.

  • Did someone even test the 1511 build before release?

    -BSOD on all machines due to this AppLocker Bug
    -ADK 1511 is broken (images won't boot)
    -Intel ANS doesn't work on build 1511 (no VLAN and teaming Support)

    Looks like Enterprise ready now means "this works for watching Star Trek".
