What do you know about svchost.exe?

What is Svchost.exe

Microsoft started modifying Windows functionality from relying on internal Windows services to use DLL files instead. If we talk about the programming perspective, this makes code more reusable and become easier to keep up to date. The issue is that you can’t directly launch a DLL file from Windows the same way you can an executable file. But a shell that is loaded from an executable file can host these DLL services. And then (svchost.exe) Service Host process was born.

The Microsoft Support site explains it as “a generic host process name for services that run or execute from dynamic-link libraries.”  Right. So that’s quite simple or straightforward, anyone can easily understand it.

Here the word “dynamic-link library” also known as a .dll file. Which is a big block of programming code.  There are many amazing tricks that developers or manufacturers can do with these files to make things run quicker and take minimum space.  The issue is that a .dll file can’t execute standalone.  You want a .exe or “executable” file to load all .dll and its code.

Now we all know a DLL file is, it should be simpler to understand why svchost is known as a “generic host.”  Well, it loads DLL files so they can execute or run the system apps.  So you don’t need to worry about it?  Well, there is the possibility that you must install or download a virus that could make your svchost load up a few DLLs from the dark side.  Keeping your PC updated with all of the MS Security Updates and executing an anti-virus app can minimize the chance of this.

So in short it’s just a host for many processes!  Now I want to know what is being executed by svchost.exe?  There are two methods to keep tabs on svchost.exe.  The first method is the command line.

Check Which Processes Are Executing Under Svchost.exe Via Process Explorer

The issue with the command line is, it brings many weird looking processes that appear as strange as svchost itself. So here is where we want to install a program from Microsoft known as Process Explorer.

Process Explorer is an amazing app written by Microsoft to help you know the bolts or nuts about MS Windows. When you have it executing, you can indicate individual processes and view what each process is doing.

Step 1:

All you need is to launch Process Explorer and take a complete look at the svchost.exe on my PC.

Step 2:

When you open it, just hover your mouse pointer over a process such as svchost.exe for details about it.

After playing around with this, you’ll then check that some of the svchost processes are executing lots of services as others. And wait, why there are many svchost.exe processes running together?

Each svchost.exe process executes services that are based on logical service groups, for instance, one might be executing network services while another might be handling device drivers. Having these services executes on separate hosts is a bright feature because this way if one dies it won’t take down your whole PC all at once.
