If you use a Windows computer, then you are likely aware of the service hosts processes listed under task manager are considered must have system processes. However, they sometimes hog space and RAM causing you all sorts of computer issues. So you do a Google search to find out what the process in hopes of solving it, only to be told “NO”. Well DCOM is one of those annoying process and why yes, you can live without it. Here is a break down of what it is, what can cause issues with it, how to disable it and the risks involved.
What is DCOM?
DCOM stands for Distributed Component Object Model, which basically allows your computer (and its software) to “talk” to other computers via remote support or networks. It comes standard on all Windows machines and for the most part causes zero issues. However, it is not vital for your system to run.
So, what does cause issues with DCOM?
DCOM has sadly become a target for worms and viruses alike. In fact a few years ago Windows had an issue with XP becoming infected often with a worm that messed with DCOM. It is sort of the ideal target since it can control how the computer communicates, but also because the system does not want it disabled. So many people do not risk removing the infection since they fear disabling DCOM will mess up their system more. However, if they continue to allow infected or damaged DCOM to run, it will mess up their entire system to a point of needing a clean OS installation.
What are the risks involved with disabling DCOM?
This is perhaps the most pending question and one that even I had a hard time finding out the answer to. Without DCOM your computer basically cannot be remote accessed or connect to certain things that need lots of communication, such as VPNs. So most home users really do not need to worry about using DCOM, while business users might want to find out what they need to run as a vital part of work. Other than that, you won’t even miss it or notice it being gone.
Okay, you convinced me. Now how do I disable DCOM?
First, please be advised that unless you are the computer admin or not feeling like you can do it yourself, please do not try. You could mess up your system if you do not know how to do it properly. So please heed this advice if you are just starting with computers.
Okay, now to the juicy stuff.
1. Go to computer
2. Go to control panel
3. Click on Admin tools
4. Click on component services.
5. Click on computers.
6. Right click on my computers and select properties.
7. Select default properties tab.
8. Uncheck enable DCOM (or distributed com).
9. Click apply and okay.
You may then have to restart your computer to successfully finish the process. After that, you have successfully disabled the service.
