Deeper Explanation

The tech vlogger provides a sub-5-minute explanation of this Windows process. He says that if you open up your Task Manager, you are generally going to see it all the time running on your computer.

So what is it, he asks?

It is a client-server runtime service- it is a process running constantly running in the background within Windows. Historically, he says, it was accountable for the entire graphical subsystem of the operating system in older versions of Windows.

But it’s still skulking around. It manages Windows drawing objects and other functions within the operating system. At some point, all the roles that it had were moved to the Windows kernel.

But it’s still in charge of the following: the Windows console shutdown process, which is vitally important and lots of additional critical functions within the operating-system.

Additionally, it commences the console host process.

Can you disable it? This is a super easy answer- you simply cannot disable the process. If you attempt to eliminate the process, you are going to run into a lot of problems. It uses a tiny amount of resources and it only executes a few essential functions within the operating system. It always launches up when you start up your computer, so don’t be concerned about it.

However, if that service doesn’t launch with your operating system, probably you’ll get the blue screen of death and that is a no-no in the IT world.

He says, that you’ve probably been told that it’s a virus. Now the process is normal whenever it runs within your Windows operating system.

He says that some tech support scammers will attempt to trap you on this and make you open up the Task Manager and identify the process as a virus.

On the other hand, the file should only live within Windows system32.

If you are exploring within your C Drive- and you notice someplace else, more than likely it is malware or viruses camouflaging itself as the legitimate file. So stop what you doing, immediately scan your machine and make certain it’s secure.
