In your Windows operating system, various files and processes run quietly in the background, rarely catching your attention. One of these is AggregatorHost.exe, a file that Windows users often encounter while using their computers.
In this article, we’ll explain what AggregatorHost.exe is, what it does, and how to determine if it’s a legitimate part of your system or a potential threat.
What Is the «AggregatorHost.exe» Process in Windows?
AggregatorHost.exe is a Windows background process that operates discreetly. This process is a component of the Windows Insider Program, designed for the testing of forthcoming features and updates before their public release.
The primary function of this process is to collect user feedback and telemetry data from participants in the Windows Insider Program, forwarding this information to Microsoft for analysis. Some users have also observed its connection with changes in Windows Defender.
Under normal circumstances, this file should reside in the «C:\Windows\System32» directory and carry a valid digital signature from Microsoft Corporation.
While AggregatorHost.exe is a legitimate component, it’s important to note that some malicious programs may attempt to masquerade as AggregatorHost.exe to evade detection within your system. This can lead to potentially harmful consequences, as these impostor files may contain malware capable of causing damage to your system.
How to Check the Authenticity of AggregatorHost.exe on Windows
If you think the AggregatorHost.exe file on your PC might not be authentic, here’s how to check:
-
Verify the location: Launch the Task Manager by pressing Ctrl + Shift + Esc keys together. Locate the AggregatorHost.exe process in the list and right-click on it. Select Open file location from the menu. The genuine AggregatorHost.exe file should be located in «C:\Windows\System32» folder. If you find it hidden somewhere unknown, it can be a malicious program.
- Check the file properties: Right-click on the «AggregatorHost.exe» file and choose Properties from the context menu. Head over to the «Details» or «Version» tab and look for information about the file, such as its version, copyright, and product name. Legitimate system files usually have detailed information.
- Check the Digital Signature: In the Properties dialog of the file, open the «Digital Signatures» tab (if it is available) or check the details of the file to verify the digital signature. A legitimate file should have a digital signature that is both valid and trusted. If the digital signature is invalid or not from a trusted source, it may be a cause for concern.
- Look for publisher information: You can also look for information about the publisher or company that created the file. Legitimate system files are typically signed by well-known companies like Microsoft.
When Should You Disable AggregatorHost.exe?
While this program generally operates in the background without disturbances, occasional issues may arise. These issues typically manifest as high CPU usage or uncertainty regarding the process’s legitimacy.
Disabling the process is a straightforward procedure. To do so, access the Task Manager and locate the process in question. Select it, then click on the Disable button, and confirm your action when prompted for confirmation.
To fix the issues that this file has caused, here are some solutions that you can try:
- Run an antivirus scan: If you suspect that «AggregatorHost.exe» is related to malware or other malicious activity, scan your system using any of the reputable antivirus or antimalware programs available and follow the recommendations provided.
-
Use the System File Checker (SFC): The malware is likely to have messed with the system files as well, so it is crucial to identify the faulty files and restore them. This can be best done using the System File Checker, which will check the integrity of your system files. If a problematic file is identified, it will replace it with its healthier counterpart.
- Uninstall other suspicious software: Do you notice any suspicious software installed on your system? If so, there is a chance AggregatorHost.exe is associated with it. The best solution in this case is proceeding with any one of the different ways to uninstall a program in Windows and get rid of it.
Hopefully, these steps will help you get rid of the harmful process and restore your system back to its healthy state.
Stay Informed and Secure on Windows
AggregatorHost.exe is an integral part of Windows, even though it might seem unfamiliar and potentially raise concerns. It is also safe to keep it on your system. However, we highly recommend keeping an eye on your system’s performance to ensure that AggregatorHost.exe and other files are not being exploited by malicious entities.

You might have seen multiple processes running in the background in the Task Manager on Windows OS. These background processes perform some particular tasks. Hence, these processes are essential for the proper functioning of the Windows Operating System. Disabling any one of these processes without knowing what that process is used for may lead to several errors in your system. AggregatorHost.exe is one of the processes that run in the background and in this post we will talk about this file.
What is AggregatorHost.exe in Windows 11/10?
The way to identify or learn more about any process is as follows:
- Open Task Manager
- Locate the process which in this case is AggregatorHost.exe
- Right-click in it and select Open file location
- Where does it take you? The System32 folder I presume.
- Now locate the AggregatorHost.exe file and right-click on it
- Select and open Properties and then open the Details tab
- Do you see Product Name or Copyright as Microsoft?
- You don’t? Then it is NOT a Windows OS file!
Checking the File location and Properties gives the real picture, but remember-
- Just because a file is located in the Windows or System32 folder does not make it a legit Microsoft or Windows OS file!
- Just because a file name is similar to another which belongs to a legit software, does not mean that this file could be associated with that software.
Microsoft and most legit software companies will always digitally sign their file. So checking the Details tab is also important.
A legit Windows OS file will always mention the details as shown above.

This is what AggregatorHost.exe Properties look like:
The Details tab of AggregatorHost exe Properties is blank and that could be a cause for concern!
So then what is this AggregatorHost.exe file? I found no real answers on the web but I am guessing that it could be an internal Windows tool or process involved in aggregating the Windows API commands across Win32/Win64 applications.
But folks on the web have said that maybe it is a temporary file that is used in Windows Insider Builds, maybe it is used by Windows Defender, maybe it is associated with Adobe products, maybe it is some benign legit file – or maybe it is a virus!
In this case, what you need to do is run a full antivirus scan. You may also use a 3rd party on-demand standalone AV scanner like Kaspersky or Dr WebCureIt. Additionally, you may upload this AggregatorHost.exe file to an online service that scans files with multiple antivirus definitions – like virustotal.com or jotti.org. If you see it in your Startup list, remove the file from it in any case.
Stay safe!

A malicious virus program such as AggregatorHost.exe can cause numerous issues to your PC and can harm your system and data files in various ways. AggregatorHost.exe is a highly-dangerous malware threat from the group of Trojan horses.
As you likely already know, the Trojan horse virus category is among the worst of the worst types of malware. Its versatile nature and its ability to silently sneak inside most computer systems makes it the perfect malware tool for a wide variety of virtual crimes such as theft, espionage, backdooring for other malware, establishing remote control without the user’s knowledge and so on and so forth.
It’s only logical to assume that AggregatorHost.exe, being one of the newest and likely one of the more advanced representatives of the Trojan horse category, can also be used in those and in many other ways depending on the specific goal of the hackers behind it. If you suspect that this noxious malware threat might have gotten inside your system, you should definitely take immediate action towards detecting the infection and getting rid of it before it has managed to cause any serious damage and harm.
The paragraphs below will offer you insight into the specifics of these threats and will provide you with the information that you might need in order to effectively clean your PC and keep it safe in the future. The AggregatorHost.exe removal instructions are available within the guide manual further down on this page. Inside the guide, you can also find a suggested anti-malware program that you can use as an additional measure against the AggregatorHost.exe infection.
So, if this malicious piece of malware is presently on your machine, we strongly advise you to read through the next lines and then visit the guide down below. Follow the steps in the guide and use the removal tool in case you think you might need additional help and ensure that the infection is taken care of as soon as possible because, as we mentioned above, there are all kinds of harm that this malicious virus might be able to cause to your machine.
Typical characteristics of a Trojan horse
One of the main traits of threats the likes of AggregatorHost.exe or Energy.exe is related to their sneaky and stealthy nature. The usual ways in which such viruses get distributed normally include some form of disguise. It is highly likely that such a malware piece could be presented to you in a seemingly harmless form. Here are some examples of content that can be used for disguising Trojans and making it more likely for the user to allow the malware inside their machines:
- Files or links attached to spam e-mails or some other form of spam online messages.
- Illegal and illegally distributed software that users can download from the Internet.
- Misleading online advertisements that can either serve as direct download links for the malware or that might serve as redirects to malware-infested pages.
- Legitimate websites that have been hacked by the online criminals and set to distribute the virus.
- Other Trojans that can be used for backdoor purposes.
There are, of course, various other popular methods for spreading such cyber threats. The ones we’ve just mentioned are simply the most common ones. Sadly, it can oftentimes be rather difficult to tell legitimate content from such that is potentially harmful. Still, staying vigilant and keeping away from potentially unsafe and unreliable online locations and content is crucial if you want to keep your machine safe in the future.
One other thing that needs to be mentioned here is the fact that a Trojan infection might oftentimes lack visible symptoms which would enable the malware to stay undetected. Regardless, if you notice any unusual system behavior, know that a Trojan horse attack might be the cause behind it. Also, make sure that you have on your PC a good antivirus tool as in many cases this could be the difference between stopping the infection on time and allowing the malware to fully carry out its insidious task.
The damage that a Trojan can cause
As we stated above, AggregatorHost.exe might have a number of different abilities which is the reason why we can’t tell you with certainty what its purpose might be in your particular case provided that the malware has attacked your computer. Data theft, blackmailing, espionage, data and system corruption, distribution of ransomware and other nasty threats and even taking over your whole PC.
However, one thing’s for certain. If you want to prevent any of this from happening to you and to your PC, you should immediately take action and try to eradicate the threat before it’s too late. If you need any further help or have any questions, our comment section is open to you, so do not hesitate to reach out to us with your request.

WARNING! READ CAREFULLY BEFORE PROCEEDING!
When it comes to malicious processes, Trojan threats like AggregatorHost.exe might use a variety of techniques to mask theirs. That’s why if you have been compromised, it’s important to launch Task Manager (CTRL + SHIFT + ESC simultaneously) and see what tasks are running on your computer when you restart it in Safe Mode.
Make a detailed search for processes that have a strange name, utilize a lot of CPU or Memory, or just appear weird and cannot be tied to any of the apps you regularly have on your computer.
An easy technique to check for malware is to look at a single process, right-click on it and choose “Open File Location” as explained in the picture below.
Next, use our free online virus scanner to check these files for malware:
Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
This scanner is free and will always remain free for our website’s users.
This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

This scanner is based on VirusTotal’s API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.
The scan results will tell you which files are dangerous, so that you can remove them. Before you do that, however, make sure that you end the related process by right-clicking on it and selecting the End Process option.
After you’ve ended the malicious processes in the Task Manager, check the startup settings in System Configuration for suspicious items that AggregatorHost.exe may have installed without your knowledge.
In the Windows Search bar, type msconfig and hit Enter from the keyboard. Next, click on the Startup tab in System Configuration and look at the startup entries that are listed there:
Any startup items that have “Unknown” manufacturer, have unusual names, or otherwise seem dubious should be investigated online before removing their checkbox. If you find enough evidence that the item is connected to a Trojan infection, uncheck the tick mark to deactivate it.
We also recommend checking your computer’s Hosts file for unwanted alterations.
In order to open it, press WinKey and R together and type the following into the Run box:
notepad %windir%/system32/Drivers/etc/hosts
Look for Localhost in the text of the Hosts file when it’s open. Odd IP addresses under Localhost, as seen in the sample image below, are a likely symptom of hacking.
Let us know if you see any strange IPs under “Localhost” in your Hosts file by commenting below this post. We’ll get back to you with some recommendations.
As a last step, you should scan the system’s registry for any dangerous entries connected to the virus, and then delete them.
Start with typing Regedit in the Windows search bar and hitting Enter.
Use the CTRL and F key combination to open a Find box in the Registry Editor. To find the Trojan, enter its name and click the Find Next button. You should remove any files or folders with that name that show in the search results since they might be infected.
If nothing comes up in the search, you may manually go to the following folders in the Registry Editor’s left panel:
- HKEY_CURRENT_USER—-Software—–Random Directory
- HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
- HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random
Search for randomly-named items, and if you think they’re part of the Trojan, delete them from the system’s registry.
If you have any doubts about what files you should remove, or if you don’t want to inadvertently damage your operating system by deleting something legitimate, we recommend downloading the anti-virus software listed on this page and running a scan with it. Another tool that we recommend you to use is the free online virus scanner that can check specific files for malicious code. If you need help with the manual removal guide and its instructions, you may always ask us any questions in the comments section below.

AggregatorHost.exe: что это в диспетчере задач?
Фоновые процессы Windows не отображаются в виде окон или каким-то другим способом. Они находятся в окне диспетчера задач. Чтобы запустить его, кликните правой кнопкой мыши на панели задач и выберите соответствующий пункт. AggregatorHost.exe – это системный процесс, который относится к Microsoft Defender. Это программа, занимающаяся защитой Виндовс, отслеживающая угроза и предотвращающая вмешательство. Она не заменяет собой антивирус, но обеспечивает средний уровень безопасности, если вы не заходите на сомнительные сайты и не открываете файлы, скачанные из них.
Интересно: Как удалить Windows Copilot в Windows 11?
Процесс AggregatorHost.exe начал появляться в диспетчерах задач пользователей после одного из обновлений, выпущенных во времена, когда 10 версия Windows была последней. Тогда люди сталкивались с проблемой, при которой центр обновления Виндовс пытался скачать новую версию системы при отсутствующем подключении к интернету. Это сильно повышала нагрузку на систему, тратя большую часть мощность комплектующих, из-за чего пользоваться компьютером было сложно. Добавление процесса AggregatorHost.exe позволило решить эту проблему.
AggregatorHost.exe – не принадлежит вирусному ПО и используется службами Майкрософт для отслеживания обновлений. При этом процесс не всегда активен в диспетчере задач. Пользователи отмечают, что он появляется время от времени. AggregatorHost.exe существует в виде файла, поэтому удалить его возможно. Но делать этого не следует, потому что тогда у вас могут возникнуть проблемы при следующей попытке обновить систему.
Опасен ли процесс AggregatorHost.exe?
AggregatorHost.exe – это системный компонент, поэтому никакой угрозы вашему компьютеру он не несёт. При этом он почти не тратить ресурсы ПК, поэтому его работа в фоне не должна помешать вам пользоваться устройством. Но по сообщениям некоторых пользователей, процессы некоторых вирусных программ маскируются под системные, чтобы владелец компьютера не заметил угрозы. Таким образом, разработчики вирусов и майнеров могут использовать AggregatorHost.exe для своих целей.
Рассмотрим, как проверить, безопасен ли файл:
- Откройте диспетчер задач и перейдите в раздел «Процессы».
- Найдите процесс «AggregatorHost.exe», щёлкните по нему правой кнопкой мыши и выберите «Свойства».
- Обратите внимание на пункт «Расположение». Файл AggregatorHost.exe должен располагаться по адресу C:/Windows/System32.
Если файл AggregatorHost.exe находится в этой папке, то процесс полностью безопасен и относится к системе обновления Windows. Если вы перейдёте по указанному выше адресу, то сможете сами найти его исполняемый файл. Такой же располагается на установочном носителе Windows. Но, если расположение показывает, что процесс запущен не из системной папки, то это может указывать на вирус. Ещё один признак – процесс AggregatorHost.exe потребляет слишком много мощности ПК. Информация об этом указывает в процентах в графах «ЦП» и «Память» диспетчера задач. В любом случае рекомендуем запустить сканирование в вашем антивирусе.
Как удалить AggregatorHost.exe?
Файл AggregatorHost.exe не защищён и удаляется, как и любой другой. Но не стоит делать этого, если у вас нет никаких подозрений. Если проверка показала, что файл, запустивший процесс находится не в папке System32, всё равно не рекомендуется сразу удалять его. Это может нанести вред системе. Сначала запустите глубокое сканирование Windows в своём антивирусе. Также можете проверить с его помощью сам файл. Если проверка ничего не показала, на всякий попробуйте установить другое антивирусное ПО и поискать опасные процессы через него.
