If you spkết thúc any time poking around through your Task Manager window, you’ve sầu probably seen a process named “Host Process for Windows Tasks.” In fact, you’ve sầu likely seen multiple instances of this task running at the same time. If you’ve ever wondered what it was & why there are sometimes so many, we’ve sầu got the answer for you.

RELATED: What Is This Process và Why Is It Running on My PC?

This article is part of our ongoing series explaining various processes found in Task Manager, like Runtime Broker, svchost.exe cộ, dwm.exe pháo, ctftháng.exe cộ, rundll32.exe, Adobe_Updater.exe cộ, và many others. Don’t know what those services are? Better start reading!


What Is It và Why Are There So Many in Task Manager?

Host Process for Windows Tasks is an official Microsoft core process. In Windows, services that load from executable (EXE) files are able to institute themselves as full, separate processes on the system và are listed by their own names in Task Manager. Services that load from Dynamic Linked Library (DLL) files rather than from EXE files cannot institute themselves as a full process. Instead, Host Process for Windows Tasks must serve sầu as a host for that service.

*

You will see a separate Host Process for Windows Tasks entry running for each DLL-based service loaded into Windows, or possibly for a group of DLL-based services. Whether & how DLL-based services are grouped is up lớn the developer of the service. How many instances you see depends entirely on how many such processes you have running on your system. On my current system, I see only two instances, but on other systems, I’ve seen as many as a dozen.

Unfortunately, Task Manager gives you no way khổng lồ see exactly what services (or group of services) are attached to lớn each Host Process for Windows Tasks entry. If you’re really curious khổng lồ see what each instance is linked to lớn, you’ll need to download Process Explorer, a free Sysinternals utility provided by Microsoft. It’s a portable tool, so there’s no installation. Just tải về it, extract the files, and run it. In Process Explorer, select View > Lower Pane lớn be able lớn see details for whatever process you select. Scroll down the danh mục và select one of the taskhostw.exe entries. That’s the tệp tin name of the Host Process for Windows Tasks service.

Looking through the details in the lower pane, I’m able to piece together that this service is linked khổng lồ my audio drivers and also has Registry keys associated keyboard layout. So, I’m going khổng lồ assume it’s the service that monitors for when I press any of the truyền thông media keys on my keyboard (volume, mute, và so on) and delivers the appropriate commands where they need khổng lồ go.

Why Does It Use So Many Resources at Windows Startup?

Typically, the CPU and memory each instance of Host Process for Windows Tasks just depends on what service the entry is attached lớn. Normally, each service will consume the resources it needs lớn do its job và then settle back down lớn a baseline of activity. If you notice that any single instance of Host Process for Windows Tasks continually uses more resources than you think it should, you’ll need to lớn track down which service is attached khổng lồ that instance và troubleshoot the related service itself.

You will notice that right after startup, all instances of Host Process for Windows Tasks may look like they’re consuming extra resources–especially the CPU. This is also normal behavior & should settle down quickly. When Windows starts, the Host Process for Windows Tasks scans the Services entries in the Registry & builds a menu of DLL-based services that it needs to lớn load. It then loads each of those services, và you’re going to see it consuming a fair bit of CPU during that time.

Can I Disable It?

No, you can’t disable Host Process for Windows Tasks. And you wouldn’t want to lớn anyway. It’s essential for being able lớn load DLL-based services onlớn your system và, depending on what you’ve sầu got running, disabling Host Process for Windows Tasks could break any number of things. Windows won’t even let you temporarily kết thúc the task.

Could This Process Be a Virus?

The process itself is an official Windows component. While it’s possible that a virus has replaced the real Host Process for Windows Tasks with an executable of its own, it’s very unlikely. We’ve sầu seen no reports of viruses that hijack this process. If you’d lượt thích khổng lồ be sure, you can kiểm tra out Host Process for Windows Tasks’ underlying tệp tin location. In Task Manager, right-click Host Process for Windows Tasks and choose the “xuất hiện File Location” option.

*

If the file is stored in your WindowsSystem32 folder, then you can be fairly certain you are not dealing with a vi khuẩn.

That said, if you still want a little more peace of mind–or if you see that tệp tin stored anywhere other than the System32 folder–scan for viruses using your preferred vi khuẩn scanner. Better safe than sorry!
