Task Host Windows: what is this process and can I get rid of it? What is Task Host Windows? What does the task host windows program do.

Familiar when, during the shutdown of the computer, a window appears with the title Task Host and a suggestion to terminate any application? Today we will consider what it is, and what methods to deal with the appearance of a dialogue that slows down the shutdown of the computer.

The essence of the process

More knowledgeable users already know that the taskhosts.exe process of the same name is responsible for the task host in Windows. Going into the task manager, sometimes you can see that it consumes 80 or even more percent of the CPU resources.

It is unrealistic to find detailed information about the functioning and purpose of the taskhost.exe file even on the Microsoft website. The only thing known is the system service that is started when each account is logged on. It is needed for the launch and proper functioning of applications that have a different launch method than the executable exe file. Taskhost.exe extracts and runs executable code located in user processes and Windows dynamic libraries. Based on this information, the conclusion suggests itself that the task host is an alternative to the well-known rundll32 and svchost, but the developers know better, especially since little is known about the application.

Why sometimes the process loads the processor to almost 100%, which slows down the computer, one can only guess. It is probably known that the service calls a significant number of dynamic libraries registered in the system at the same time, which increases the load on the CPU during times of relative inactivity. In addition, he constantly refers to rundll32.exe, which loads dynamic libraries to perform the functions assigned to them. Even in the task host there is an active function related to the task scheduler.

Another thing to know is the location of the file: the "system32" directory in the Windows system directory. If a different path is specified in the task manager, malware is probably running. In this case, scan your computer for viruses, for example, using a domestic AVZ product with updated databases.

Often, tskhost.exe loads the processor due to scheduled system maintenance (defragmentation, cleaning). If a clock icon is displayed next to the Action Center icon, there are scheduled tasks.

You can view their list in the scheduler along the path "Microsoft\Windows\TaskScheduler". How it starts, read the next paragraph.

Disable taskhosts.exe

The slowdown in shutting down the computer, as a rule, does not occur due to the functioning of the task host executable itself, but due to the use of resources of active applications (especially background ones), services and processes.

By closing the process just before shutting down the computer, you can speed up its shutdown, but the taskhost.exe process will automatically start after the next Windows boot.

In order to speed up the shutdown of the PC, we perform the following chain of actions.

Warning: To perform the following steps, you must have system administrator privileges.

• We start the task scheduler by any convenient method:
  • through the "Administration" item of the "Control Panel";
  
  
  • by means of an appropriate query in the Windows search bar;
  
  
  • by entering the Taskschd.msc command.
  
  


• We put a tick in front of a single item to activate the option to display hidden icons.

• In the scheduler library, follow the path: Microsoft - Windows.


• Let's go to the "RAC" group.

• We select the only scheduled process called "RacTask" and disable it through the action bar located on the right, or the context menu.


• To disable the task host before restarting Windows, we call the task manager and end this process.

Surely, many users of Windows 7/8/10 operating systems often encountered such a problem: before turning off their own PC, a window pops up and asks to disable Task Host Windows. What is it, we will consider today in the article and talk about ways to fix this problem.

First of all, let's understand what the Task Host Windows program is. Maybe it does not cause any harm at all, but only inconveniences the user? Not really.
Task Host Windows (the taskhost.exe process is responsible for it) is a task that ensures the normal functioning of the runtime libraries. They contain a colossal set of programs necessary for the normal operation of almost all software and the Windows system itself as a whole. Disabling or missing taskhost.exe will cause instability in other programs and processes.

Thus, getting rid of Task Host Windows is not worth it, because this can lead to other problems, which will be much more difficult to solve.
The file itself is located in the System32 folder (C:\Windows\System32) and weighs only about 50 KB. Some believe that this program is a virus and, having found it, they delete it. Under no circumstances should you do this. Taskhost.exe is completely safe and is originally embedded in the Windows operating system itself. Unfortunately, due to the fact that this file is one of the most important, it is a tasty morsel for most viruses.

How taskhost.exe works

With the question: “Task Host Windows - what is it?”, We figured it out. Now let's see how this process works.
The executable taskhost.exe takes the code to be executed and runs it. In fact, this process is an alternative to the well-known svchost.exe and rundll32.exe (but probably more successful).
Little is known about the application, so one can only guess why it sometimes loads the process up to 100%. Most likely, the settings are made in such a way that there are no freezes when launching applications and programs quickly start their work. Judging by the fact that taskhost.exe regularly accesses rundll32.exe and the dynamic library, it can be called some kind of compiler.

Disable the process

The constantly popping up window is starting to get annoying, so let's look at ways to disable Task Host Windows - how to fix the problem so that you forget about it forever.

In general, when you turn off a personal computer, Windows starts to slow down not because of the taskhost.exe process itself, but because of the programs that it manages. About two dozen programs can run in the background, so it takes a certain amount of time to close all of them.
It follows that there is simply no point in disabling the process, because in this case, your applications simply will not function normally. But to remove annoying notifications - why not. For this:

1. Go to the "Start" menu, open the "Control Panel", select "Administrative Tools", then "Task Scheduler";
2. Now open the "View" tab and check if the box next to "Show hidden icons" is checked;
3. Then follow the path (drop-down list on the left) "Task Scheduler Library" - "Microsoft" - "Windows" - "RAC";
4. After that, the RAC Task field will open, where you need to click on the file and select "Disable".

All! Now notifications will turn off, and the process will no longer bother you.

We figured out the Task Host Windows and found out that this is not a malicious program at all, but a very necessary process. But it's worth reading anyway.

taskhost.exe virus

As mentioned above, Task Host Windows is a tasty morsel for all kinds of viruses. They disguise themselves as this file and carry out malicious activities, so to speak, “under cover”. The first, and most important, point that you should pay attention to is the system boot. If there is a strong freeze for several minutes, then most likely you have encountered a virus. Here are some other signs of infection:

• By default, taskhost.exe is located in C:\Windows\System32. Any other file location is an alarm call;
• The file itself weighs a lot - 150Kb or more with an "original" size of 50Kb;
• As soon as it starts to work, there is a sharp increase in CPU load (monitored in the task manager);
• When finished, the process starts again.

Are there signs? So you need to deal with the following question: how to remove the Task Host Windows virus.

We remove the virus

The removal process is quite simple. Just follow the instructions:

1. We end the taskhost.exe process (from the "Task Manager", right-click on the process - "End");
2. Open the folder with the file ( NOT folder C:\Windows\System32) and delete taskhost.exe;
3. This virus is an ordinary Trojan, which means that any antivirus will perfectly cope with it - just scan the system.

We have analyzed the main points related to Task Host Windows - what it is and why it can turn out to be a virus. Do you have any questions? Write in the comments and we will help!

Most users are faced with a situation where the taskhost.exe process is in a running state. This happens for a number of reasons, including when one of the applications crashes. In this case, the running taskhost.exe process is observed in the standard Task Manager.

What is the Task Host Window?

Literally translated from English, this means "task host window". However, the use of this term is usually inherent in operating systems. In other words, this concept refers to the Taskhost Windows process or service. It is worth noting that when searching for a description of a service on the World Wide Web, a query like "Taskhost Window" is not applicable.

Thus, this is a paramount error in the naming of the process itself. As for the service itself, it can be described as a kind of launch component for additional software libraries of the DLL type that cannot be launched in the traditional way in the form of opening an executable EXE file. It is worth analyzing the concept of Task Host Windows in more detail.

What is the principle of the service?

Task Host Windows is a system process. When considering this concept in more detail, it is worth using the use of dynamic libraries as an example. As is clear from the translation, the application does not use its own task window. In the Windows operating system, not all utilities can be run exclusively from executable files.

There are also programs that have extractable program code contained in dynamic libraries. Examples are most plugins that connect to music sequencers, as well as ordinary software players, including WinAmp or AIMP. They are the owners of just such a format of libraries that are triggered when access to them is requested.

As you know, the equalizer for the player does not start separately. You need to use the main program. However, in the software to which it is connected, the plugin does its job perfectly. There is also another question to think about. According to the developers, the service is responsible for running applications and libraries on 32-bit systems.

And they, as you know, differ from executable components. It is worth noting that there are two more similar services in the system itself - Rundll32 and Svchost. The first one is used only when running dynamic libraries in 32 bits. The second service is related to running applications in general. Thus, it turns out that the Taskhost Window is an ordinary stand-in for the two processes described above.

Shutdown

Finally, it is worth saying a few more words about the Task Host Window service. More precisely, about the shutdown in the system and the consequences of this. I would like to note right away that nothing bad happens in this case. In other words, there are no negative consequences for the system. Thus, it can be argued that users who criticize the complete disabling of this process are completely wrong.

Nothing bad will happen. Based on practice, disabling the described service in many cases leads to the release of system resources. It also improves performance on any Windows operating system, regardless of version.

The article answered in detail the question of what Task Host Windows is and what are the principles of this process.

Familiar when, during the shutdown of the computer, a window appears with the title Task Host and a suggestion to terminate any application? Today we will consider what it is, and what methods to deal with the appearance of a dialogue that slows down the shutdown of the computer.

Starting with Windows XP, and then Vista, 7 and 8, many users are faced with the functioning of the inexplicable taskhost.exe process. Most users have no idea what taskhost.exe process is currently running. In addition, sometimes the load on the central processor can reach almost 100%. But is it possible to disable the program, and how to do it so as not to harm the entire system, we will now find out.

taskhost.exe process: what is it?

Finding a detailed description of the process itself is not so easy, not to mention the principles of operation of this system service, run on behalf of a user in a local session with the LOCAL SERVICE, SYSTEM attribute, or an attribute that displays the username.

No, this is not a user process in the sense that it is launched by a user, this is a system service, but it starts at each specific user login under their accounts.

So, the user observes in the "Task Manager" the running active process taskhost.exe. What is it from the point of view of the system itself? According to Microsoft's short description, this service is responsible for running 32-bit applications in a form other than standard .exe executable files. The process itself is similar to the services svchost.exe and rundll.32.exe, since it is able to simultaneously launch user processes and local session services with the extraction of executable codes and commands located in dynamic libraries of the .dll format. It is not clear, however, why it was necessary to create a duplicate service, but, as they say, Windows developers know better.

Why is the taskhost.exe process loading the processor?

In theory, if you look at it, the process itself is indeed a system one, although it starts in every user session. Based on the foregoing, it is easy to guess that the excessive load on the processor may be due to the fact that this service alone calls all registered processes from dynamic libraries (and does not “hanging” in the process tree in the form of several services like svchost.exe). In addition, do not forget that the rundll32.exe service also accesses the libraries, but, apparently, it is the taskhost.exe process that has priority. What does this mean for the system? Yes, only that very often there is an unforeseen conflict between processes that seek to be the first to load this or that library.

In addition, many experts attribute the increased consumption of system resources to the fact that the process itself contains the activated RacSysprepGeneralize function, located in the dynamic library RasEngn.dll, which belongs to the standard Windows Task Scheduler.

Is it possible to disable the taskhost.exe service?

Now a few words about whether it is possible to do without this annoying process in the system. Yes, you can. However, it will not work to disable the service by force in the "Task Manager". Rather, it is possible to complete the process, but, as practice shows, after a while it will “resurrect” again.

Methods for shutting down a process

First of all, you can try to disable the "Task Scheduler" itself. But this does not always help, since the above RacSysprepGeneralize function will still work.

To get rid of it, you need to enter the "Task Scheduler Menu" section, called from the "Control Panel" with a sequential selection of the "Administration" and "Task Scheduler" sections, and then repeat the sequential transition through the "Microsoft" sections, then "Windows" and "RAC". Now in the "View" menu you will need to specify the display of hidden icons, and then use the right click on the RACTask or RACAgent service (for Windows 7 and Vista, respectively). In the submenu that appears, select the "Disable" command, and then end the taskhost.exe process again in the "Task Manager".

If it's a virus

Not always, however, such a service can be classified as a system component. In some situations, another suspicious service (or two or more with the same or non-system attributes) taskhost.exe may also be present in the process tree. What is it in this case?

A common computer virus that will need to be deleted or cured with the original file using stationary anti-virus software or using anti-virus utilities that are loaded even before the OS starts. But, as a rule, such situations are extremely rare.

Outcome

So we looked at the taskhost.exe process, how to remove it or get rid of malicious threats. In general, the first way to disable the components of the "Task Scheduler" is the most common, and without any intervention in the system registry or in the operation of the "OS" as a whole. As practice shows, disabling this service does not affect the system, but it frees up additional resources.

However, as is already clear, the above steps to disable the taskhost.exe process must be performed only when accessing a computer terminal with administrator rights. Otherwise, this action will not take place.

Roughly speaking, the user will not only be unable to disable the relevant services, but in some cases will not even be able to enter the “Control Panel” to make any changes, because sometimes access can be blocked so that the “Control Panel” tab in the menu “ Start” is not even displayed, not to mention that it cannot be called from the command line, no matter how hard you try.
