Windows Start Menu Locked Up, unable to restart machine.

Have a situation where installing SOPHOS causes the Start Menu of Windows 10 1709 to stop working, also seems to stop all "User Experience" things, such as Settings Page etc. When you try to restart, you get the error:

task host is stopping background tasks windows 10 Device install reboot required

You have to hard kill it to reboot/shutdown the machine. 

This is a fresh installation of USB
Installed Acrobat Reader, Media Player classic, Irfran View, GreenShot, Chrome and Java.

Used the new Deployment from SOPHOS MSP Admin Console and the "Download Complete Windows Installer"

Used the following command to install:
SophosSetup.exe --customertoken="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx" --mgmtserver="dzr-mcs-amzn-us-west-2-fa88.upe.p.hmr.sophos.com" --products="antivirus;intercept" --quiet

I seem to be able to "jostle" the start menu by right clicking on the start button.  

At this stage, I am unable to install SOPHOS AV

  • Hi All,

    I installed Windows 1703 and replicated all previous steps I took with 1709.  

    It installed fine, and after the reboot no issues. 

    The issue has something to do with 1709.

  • Hi,

     

    Thanks for replying.  As this has sometime to do with the SOPHOS' internal mechanics and Windows, it is beyond me to fix it. I am unsure why SOPHOS have not fixed it yet, but I can not provide any other answer than to re-install. 

     

    I am sorry for the inconvenience.

  • If anyone gets this please respond. We are getting this on every new Dell machine we deploy. We do a fresh install of Windows 10 Pro, Install all updates and then Sophos.

    With nothing else on the machine it becomes unusable. Right now we have no answer and have tried everything we can think of to test and fix.

    If you have other software such as Malwarebytes active protection it can cause simliar behavior but this is happening on vanilla workstations out of the box with nothing installed.

    Just opening task manager 100% the CPU and takes up to a minute to release and open.

  • Hi We are also experiencing this issue. In addition to the start button we noticed edge and settings do not function either. The problem seems to be worse if doing a reboot of windows 10. We have tried rebuilding windows 10 3 times and on a new disk but still it fails.

    We have noticed  this problem on 3 systems we know of and assume more users are affected. We will log a case as this issue needs resolving urgently.

  • Hi

    My laptop, which was working fine now no longer works. I had to uninstall SOPHOS, reboot and then it worked.

    I've also just had a client who has SOPHOS Home who is unable to use their machine now.

    I think it is Hitman Pro

  • Yep same here, removing Sophos and it all works fine. I can understand the difficulty of this issue as it seems to have only occurred since windows released 1709, but nonetheless Intercept X etc is expensive and currently we have unprotected systems with others potentially with the same issue. I thought as long as we always shutdown and avoid restarts it would be a workaround,but it seems this does not always work. The only other workaround we have is to create a second windows profile and log off and into the second profile and back again, this seems to work, but not something we can ask users to do. Kevin
  • Can you explain please?

    Are you saying for at least some time if you shut the machine down and do a cold start instead of rebooting it did not happen? Is that what you mean?

    The profile thing is just strange I will try that on my lab machine now.

  • Interesting, I was unaware of the profile part.

    So, if you leave SOPHOS AV installed, but remove InterceptX, are you getting resolution?

    What use to work was, install 1706 or some earlier version, and then update to 1709 (or the latest) and everything will be fine, however, this does not appear to be the case.

    Lodging a ticket with SOPHOS is going to take a while, but maybe I have to.

    I am unsure about this Shut Down / Restart thing, this is new, did you find these action affected this bug?

  • FYI we have a partner ticket open with escalation and I will post the details here for sure.

     

    Wait how long has this been a known issue? I thought we found a bug not something that has been known for a long time. That is very concerning.

    In our test lab (about 20 machines) every IX the machine is basically toast. With that said I did a new Dell yesterday with only EPA and it did not blow the machine up but it ran poorly. For example it took about 45 seconds to open task manager. We ad no choice but to deploy it without protection other than Windows Defender because of time constraints.

  • Apologies I did not explain this too well. I have one user where if we shutdown and start it up each day, it generally works ok, but will fail if a restart is done for whatever reason. We suspect other uses are doing this. Another system seems to fail more consistently whether starting up or a doing a reboot. We spent a lot of time rebuilding systems trying to isolate the issue and found adding a second windows user profile helped a little instead of shutting down and rebooting each time trying to get it to work. So log out of one profile and into the second one and back again and this seems... to work, well as a poor workaround I know. Kevin
