Right now you are in the " Am I infected? " forums. I don't believe this is a malware problem,
so this thread should be transferred to the windows 10 support forums. You will find more suited help there. (windows10-support)
i come then from forum "am i inffected?"
i don't know how to transfert all the posts.
then the begin is:
Unable to run mmc.exe and all its dependent processes.
All restore points are lost
Chkdsk problem on c: solved
Chkdsk problem on d: resolved
Sfc / scannow stops at 37%
Dism / Online / Cleanup-Image / ScanHealth does not work, error 193
Problems since the maj winupdate of May 9, 2017 (coincidences?)
see also detail hardware and soft in my settings.
when i run mmc.exe i receice the message error:
mmc.exe - image incorrect ... c:\windows\system32\mmcbase.dll n'est pas concu pour s'exécuter
sous windows ou il contient une erreur.installer a nouveau le programme...
i clic ok in the box and it is all.
the same occur for "gestion de disque" for event viewer..., "gestionnaire de peripheric"...
there is a list here of this tasks:
MMC.exe is a core administrative process of Windows that should only be running when a related Component Obect Model – aka “snap-in” – is running. This process is built-in to every modern version of Windows and shouldn’t be causing any problems. However, if you are not running a snap-in and see this process in the Task Manager there is a chance that it is a virus disguising itself as an otherwise legitimate service.
i have try also to repare win 10 pro whith a usb iso of windows!(in open windows)
it stop too after about 30%
at boot it is not possible to reinstall windows with my files and applic(with usb)
then I arm myself with patience and expect a new inspiration.
thank for your help
