Task host prevents you from turning on the computer. We remove the HD Task ad virus. What to do if Task Host Windows does not allow you to turn off your computer

Task Host is smart Windows program 7, which starts when the operating system is turned off. When you shut down or restart your computer, Task Host checks everything running programs And background processes in order to avoid data loss. If some of the programs contain unsaved information, for example, a document Microsoft Word, then Task Host will prompt you to cancel shutting down your computer so you can save the document.

It is recommended that you close all running programs before turning off your computer. This way, Task Host will quickly check background processes and your computer will shut down immediately. However, if you have closed all programs, but Task Host Windows 7 still slows down when turning off the computer, then you need to try the following solutions to this problem.

Solution 1: Change WaitToKillServiceTimeout via Registry Editor

The WaitToKillServiceTimeout registry determines how long the system waits for services to stop and programs to close before the computer shuts down. This registry is only used when the user clicks the Shutdown button. To change the time it takes for services and programs to stop, follow these steps:

1. Simultaneously press the key Windows and R. Enter regedit and press OK.

2. Go to the following address:

HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Control

3. In the window on the right, double-click WaitToKillServiceTimeout and change the value to 2000 , click " OK" The default value is 5000.

3. Now go to the following address:

HKEY_CURRENT_USER -> Control Panel -> Desktop.

4. Click right click mouse on folder Desktop in the left panel, then select “ Create»> - « String parameter" Enter line title WaitToKillServiceTimeout.

4. Now right click on the newly created line WaitToKillServiceTimeout and select " Change" In field " Meaning» enter 2000 and press " OK».

Exit Registry Editor and restart your computer. Now check if the problem with Task Host Windows 7 slows down when turning off your computer has been resolved.

Solution 2: Disable services when Windows starts

You can also disable third-party services that start when booting Windows 7. As we said earlier, before turning off your computer, you should close all running programs. However, many of them run in the background, making it difficult to close them manually.

Luckily, you can use the following solution to close all background services on your computer.

1. Press the key Windows and R. Enter msconfig and press OK.

2. Select the tab " Services».

3. Check the box next to “ Don't show Windows services».

4. Click the button Disable all».

Solution 3: Install a Windows hotfix package

If the first two solutions did not produce results, and Task Host Windows 7 slows down the computer shutdown, then we have saved a 100% method for you.

Microsoft is aware of this issue and has released a fix package. Click to download the fix pack and follow the on-screen instructions to install it.

That's all! We are sure that one of these solutions will help you when Task Host Windows 7 is slow to shut down your computer.

Do you know when, when you shut down your computer, a window appears with the title Task Host and a proposal to terminate an application? Today we’ll look at what it is and what methods to deal with the appearance of a dialogue that slows down the computer’s shutdown.

The essence of the process

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

Find detailed information information about the functioning and purpose of the taskhost.exe file is unrealistic even on the Microsoft website. The only thing that is known is a system service that starts when you log in to each account. It is needed to launch and properly function applications that have a launch method different from the executable file. Taskhost.exe retrieves 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 a process loads the processor to almost 100% and slows down the computer, one can only guess. It is certainly 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, it constantly accesses rundll32.exe, which loads dynamic libraries to perform the functions assigned to them. The task host also contains an active function related to the task scheduler.

What else you need to know is the location of the file: the “system32” directory in system directory Windows. If a different path is specified in the task manager, it probably works malware. In this case, scan your computer for viruses, for example, using the domestic product AVZ with updated databases.

Often tskhost.exe loads the processor due to scheduled system maintenance (defragmentation, cleaning). If a clock icon appears next to the Help Center icon, it means there are scheduled tasks.

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

Disable taskhosts.exe

As a rule, computer shutdown slows down not due to the functioning of the task host executable file itself, but due to its use of resources active applications(especially background ones), services and processes.

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

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

Important: You must have System Administrator privileges to perform the following steps.

• We launch the task scheduler using any convenient method:
  • through the “Administration” item of the “Control Panel”;
  • by means of a corresponding request to search bar Windows;
  • by entering the command Taskschd.msc.
• Check the box next to the only item to activate the option to show hidden icons.

• In the scheduler library we follow the path: Microsoft - Windows.
• Let's go to the "RAC" group.

Since you are a user of the Windows operating system (and it doesn’t matter whether it’s version seven, eight or newest windows 10), there is a high probability that you have encountered such a problem as a long shutdown of the computer when all its processes are turned off - a complete shutdown of the computer.

In this article you will find out what kind of Task Host process this is, what is needed for it to work correctly, is it a virus or executable windows file and how to remove it in case of malfunction.

Task Host Windows - what is it?

First, let's look at what this process actually is. Task Host Windows (signed in the task manager as “taskhost.exe”) – operating system program windows systems which is responsible for the correct operation of the executor's libraries. Through this process, all programs installed on your computer gain access to DLL libraries. From here we can draw a logical conclusion that if the computer hangs for a long time when it is turned off, it is often not the Task Host Windows (THW) process itself that is to blame, but some program that this moment uses "taskhost.exe" for its own purposes.

Important: without finding out the exact reason for the slowdown of your desktop computer or laptop running Windows OS, deleting “taskhost.exe” is prohibited; this action will lead to damage to system files and unstable work systems as a whole.

How does the program work?

Because Microsoft does not disclose detailed descriptions their programs - little is known about Task Host Windows, but we can say with complete confidence that “taskhost.exe” is system file, which was implemented by itself operating system for stable and quick launch everyone installed programs. In fact, these are the same infamous “svchost.exe” and “rundll32.exe” (though in a more successful version), which works immediately after you try to launch any program on your device.

Important: the routine file is located in the System32 system folder “C:\Windows\System32” and weighs only 50Kb. This is why it is so often confused with a virus file and deleted without even trying to understand the problem.

As mentioned above, little is known about this process, so not everyone can give an exact answer why this program sometimes loads your CPU up to 100%. However, after analyzing the operation of THW, we can make some guess that the process settings are made in such a way that the programs associated with it are launched without freezes and as quickly as possible, which is why the processor is used to its full capacity at this moment.

Why might shutdown be slow?

Since Task Host is smart program and every time you turn off or restart the computer, it starts automatically, it checks all running programs, files and background processes in order to avoid incorrect termination of their work and loss of data. This is where it comes from: if any program is running (for example, Microsoft Word), and you are trying to turn off your PC, then Task Host will not allow you to do this until it checks the functionality of this program and offers to save unsaved information.

How to disable Task Host Windows?

As described above, disabling this process is extremely undesirable. However, if this process behaves too suspiciously, then it can be disabled for a while in order to later check it with an antivirus program system folder System32 for the presence of virus programs.

So, the first thing you should do is open the Start menu and launch the Taskbar. There, select “Administration” and launch the “Task Scheduler” application.

Important: in the View tab, you must check the box next to “Show hidden tasks.”

Then you will see a RAC Task, in the properties of which you must select to disable this program.

That’s all, now you won’t see the annoying “taskhost.exe” program window, which is responsible for closing applications when the computer is turned off.

Is taskhost.exe a virus?

If, after disabling the process, your system still experiences some difficulties when shutting down, you may be dealing with a virus that has very successfully disguised itself as the taskhost.exe executable file.

Here are a few signs of a virus that has replaced the original process file:

The file taskhost.exe is located in C:\Windows\System32. If, after checking, it is found in any other place, it is a virus.

The original file weighs 50 KB. (no more, no less).

As soon as this process starts working, there is a sharp increase in the CPU load by 100%, and this happens constantly, and not just once when starting a program.

Having completed the process forcibly (manually), it starts again (automatically every time).

If at least one of the signs matches, then most likely there is a VIRUS in your computer.

The next paragraph will tell you how to delete a file infected with a virus?

How to delete?

Removing a virus file is quite simple. To do this, use the key combination “Ctrl+Shift+Esc” to open the task manager and in the “Processes” tab, find the taskhost.exe process and right-click on it to call context menu, where click on “End process”. Then open the folder with the file (C:\Windows\System32) and use RMB to delete this executable file.

The last step will be to scan your system with any antivirus software installed on your computer.
