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

Host Process for Windows Tasks is an official Microsoft chip core process. In Windows, services that load from executable (EXE) files are able khổng lồ institute themselves as full, separate processes on the system and 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 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 và 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 to see exactly what services (or group of services) are attached to each Host Process for Windows Tasks entry. If you’re really curious to see what each instance is linked to, you’ll need to download Process Explorer , a không lấy phí Sysinternals utility provided by Microsoft. It’s a portable tool, so there’s no installation. Just download it, extract the files, và run it. In Process Explorer, select View > Lower Pane to lớn be able to see details for whatever process you select. Scroll down the list 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 khổng lồ piece together that this service is linked lớn my audio drivers and also has Registry keys associated keyboard layout.

So, I’m going to lớn assume it’s the service that monitors for when I press any of the truyền thông media keys on my keyboard (volume, mute, and so on) & delivers the appropriate commands where they need to go.

Why Does It Use So Many Resources at Windows Startup?

Typically, the CPU và memory each instance of Host Process for Windows Tasks just depends on what service the entry is attached to. Normally, each service will consume the resources it needs to vị 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 track down which service is attached khổng lồ that instance & troubleshoot the related service itself.

You will notice that right after startup, all instances of Host Process for Windows Tasks may look lượt thích they’re consuming extra resources–especially the CPU. This is also normal behavior và should settle down quickly. When Windows starts, the Host Process for Windows Tasks scans the Services entries in the Registry và builds a các mục of DLL-based services that it needs khổng lồ 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. Và you wouldn’t want lớn anyway. It’s essential for being able to lớn load DLL-based services onto your system and, depending on what you’ve got running, disabling Host Process for Windows Tasks could break any number of things. Windows won’t even let you temporarily over the task.

Could This Process Be a Virus?

The process itself is an official Windows component. While it’s possible that a vi khuẩn has replaced the real Host Process for Windows Tasks with an executable of its own, it’s very unlikely. We’ve seen no reports of viruses that hijack this process. If you’d like to be sure, you can kiểm tra out Host Process for Windows Tasks’ underlying file location. In Task Manager, right-click Host Process for Windows Tasks & choose the “Open tệp tin Location” option.


If the tệp tin is stored in your WindowsSystem32 folder, then you can be fairly certain you are not dealing with a virus.

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!
