    Please help, mmc.exe is inaccesable and DISM has problems


    Okay so I have been working on this for close to 10 hours between last night and today and it is way beyond old. I discovered last night that I was unable to access device manager and upon further inspection can not access most administrative tools that worked fine a few weeks ago; most of those use mmc.exe. When attempting to access them the user account control tells me the app has been blocked for my protection and to contact the administrator. Being the administrator I was a little irked. This is what I see when I try to run them. I do not need a work around I have one of those already I just need it to work.

    In attempting fixes I did a system file scan and then started to run DISM /Online /Cleanup-Image /RestoreHealth to see if that helps. Everywhere I look people have pictures uploaded that show a progress bar below the image version... well i let it run for an hour and got no progress bar...

    Welcome to the TenForums.

    Have you considered system restore to a point in time where all was working. Say in the December 6th range. (Hoping system restore is enabled and not blocked.)

    If blocked inside current windows may have to try through troubleshooting menu. Hold shift key down and reboot to access.

    If this works please consider Macrium Reflect. Its free and it ability to save an image and get you back to where you were is invaluable.

    Are you running the Home or Pro version of Windows 10? That block for MMC & Devmgmt could be a malware file if you downloaded it from the Internet. Those warnings come up from the protection layers that are built into Windows 10 to protect the OS from the bad habits of the user.

    I am running Home and I have run multiple malware cleaners in the last 2 days and I have not found anything that would cause this. It is like windows not not recognize the certificates for those tools.

    You downloaded a malware disguised as MMC is why you are getting that error. Home does not come with mmc, also depending on what you used to scan, would not find the malware if it is disguising itself as a real process.

    So I have run everything there and A bunch more as well. I don't think this is a malware problem, I have not downloaded anything in the last 26 days aside from the last 2 days. Also MMC is what controls administrative tools like device manager and firewall settings and stuff I don't see how it could even be left out of the home version.

    You need to go through the steps spelled out in that Link I posted. You computer is infected as the screenshot shows. MMC.exe is known to be used by Malware in an attempt to disguise malware. Also Home does not come with MMC, there is no need to have MMC on Windows 10 Home or Pro. It is now a Domain only feature on Enterprise editions.

    The built in Firewall allows you to set rules in it. You do not need the Firewall enabled when on your own network. The firewall is not going to stop you from being infected. It just allows you to block requests like Cortona from calling home.

    Well I ran another of the cleaners from the link although that one was just for adware. It said it needed a restart and while restarting it crashed and went through a memory check. When I was able to log in again both problems were solved. Well I have a new problem with DISM but I am working on that.

    As long as you went through step by step, you should not have had a DISM error, unless the infection was deeper than you thought.
