What Is Microsoft Management Console

In fact, the Microsoft Management Console (also known as MMC) is a vital component of Windows operating systems since Windows 2000. It is designed for all system administrators and advanced users. What can you do with the MMC?

  • You can customize the console, configure and even monitor the system.
  • You can make it easy to create, save and open administrative tools, also called consoles.
  • You can keep all the software, hardware, and network components of the Windows operating system under control.
  • You can create various custom tools and then assign them to other people according to needs.

The Microsoft Management Console is capable of hosting snap-ins (Component Object Model components) because it provides a common framework. And most of the administrative tools you can find in Windows are implemented as MMC snap-ins. As a result, several services in Windows can be managed easily within a single interface.

What Makes Your Microsoft Management Console Not Responding

You are likely to lose control over tools like Computer Management, Event Viewer, Task Scheduler, Component Services, and Windows PowerShell Modules while working on a Windows computer. Anyone of the snap-ins could crash suddenly; when it does, you should suspect that the following factors are responsible for Microsoft Management Console error.

Tip: Sometimes, the MMC cannot initialize the snap-in. Click here to know how to fix mmc snap in error.

Possible cause 1: certain system files get corrupted.

To be honest, data corruption is the number one cause for many errors on the computer and other devices. Unintended & unexpected changes could be made during writing, reading, file saving, and transmission process, bringing damage to the original data so as to lead to errors.

But fortunately, users can repair the corrupted system files through a simple SFC scan or DISM scan.

Possible cause 2: bad Windows 10 upgrade.

According to users’ feedback, Microsoft Management Console stopped working error starts to appear now and then after they have upgraded to Windows 10 from an older Windows version. The root reason is also corrupted files (the necessary files may get corrupted during the process to cause the error).

Possible cause 3: issues with Local Computer Certificate Store.

Many users reported the system gives them a Microsoft Management Console has stopped working error window when they are trying to add a snap into the MMC. In this case, a Windows 10 glitch seems to be the most possible reason for that error.

Possible cause 4: the opening of Inbound Rules of Windows Firewall.

If you try to open the Inbound Rules of Windows Firewall, you may also find your Microsoft Management Console not responding Windows 10. Some users then find the error results from a silent Windows update. Microsoft has already fixed such issue, so you should go directly to install every pending Windows Update.

Warning: Though the mmc.exe application error can be fixed after installing the pending Windows update, it may cause file loss on the device. Please use MiniTool to recover files after the Windows update ASAP!
