Some sources referred to the MMC error due to a wrong or absent video driver.

Has anybody encountered the same problem? Does anybody know how to fix it? Searching the internet, I found several instructions, basically as shown on this site I tried modifying the registry, enabling net framework, renaming mmc.exe, running DISM ( error code 87) and system file checker (sfc) in cmd.exe, as well as disabling and deleting NVIDIA video driver for GTX 970 graphics card, which is also connected in the PC, and installing microsoft update KB2966583.īut nothing worked! Task scheduler still won’t run and is showing the MMC error. I have managed to install Windows 7 Professional on my computer and everything is working well, except for the task scheduler, which shows an error “ MMC could not create the snap-in”…

Is there a working 64-bit Win 7 AMD video driver for the Ryzen 5 5600G and B550 motherboard?
