Microsoft Management Console (MMC) is an inbuilt feature in Windows operating system that lets you to manage snap-in on the go (you can run mmc.exe command to access it). The snap-ins are nothing but a basic component of a console. In the language of set theory, we can say that if a console is a set, then snap-in is its sub-set.

The various snap-ins available in Windows 8 or later editions are Event Viewer, Services, Group Policy Editor, Task Scheduler, Resultant Set of Policy (RSOP), Print Management, Windows Firewall with advance security, Performance Monitor, Device Manager, Disk Management etc.

Sometimes, there may be a possibility of scenario in which some snap-ins may not work properly. Especially, if the registry configuration of a snap-in is broken (note that Registry Editor is not a snap-in), the snap-in initialization would fail. In this case, you’re likely to get following error message (an specific message in case of Event Viewer):

MMC Could Not Create The Snap-in. The Snap-in Might Not Have Been Installed Correctly For Event Viewer

In some cases, you can also receive:

MMC cannot initialize the snap-in.

If you observe the first error message, at last line there is a hint which can help us to identify the cause of this issue. In our case, the last line of error message is CLSID: FX:{b05566ad-fe9c-4363-be05-7a4cbb7cb510} which helped to us investigate futher about this problem. We started our research by searching this string in Registry Editor. Consequently, we found that issue get resolves with fixing the corresponding registry key for Event Viewer snap-in.

Here are the steps, you need to follow in order to overcome this hiccup:

    Done it, but after restart it won’t work. Mentioning I’m doing this in safe boot mode because (it seems) my graphics card failed and I’m trying to enable the integrated one. Only that device manager doesn’t work and couldn’t find any other way to disable the dedicated video card so far.

    Hi Kapil………I have had this problem with Device Manager on a Windows 10 system. This looked like a solution so I made the changes suggested, however when I rebooted and went to check Device Manager, I got the error message “MMC could not create the snap-in.” Is there anything else you can suggest to help me sort this problem out? Thanks.

    ^^ Try taking ownership of the registry key first, then delete it. Ref: https://www.kapilarya.com/manually-take-ownership-windows-8

  • richard

  • Kapil Arya

    ^^ It won’t create any problem provided you delete the correct registry key. Still if you’re not sure, right click on the registry key and select Export to backup registry key into .reg file. This file can be later imported to restore the key.
