Malwarebytes’ — популярная антивирусная утилита, которая сообщает вам, если sihost64.exe на вашем компьютере отображает назойливую рекламу, замедляя быстродействие компьютера. Этот тип нежелательной рекламы не рассматривается некоторыми антивирусными программами в качестве вируса и таким образом не удаляется при лечении.
Чистый и аккуратный компьютер является ключевым требованием для избежания проблем с ПК. Это означает: проверка на наличие вредоносных программ, очистка жесткого диска, используя cleanmgr и sfc /scannow, удаление программ, которые вам больше не нужны, проверка Автозагрузки (используя msconfig) и активация Автоматического обновления Windows. Всегда помните о создании периодических бэкапов, или как минимум о создании точек восстановления.
Если у вас актуальная проблема, попытайтесь вспомнить последнее, что вы сделали, или последнюю программу, которую вы установили, прежде чем проблема появилась первый раз. Используйте resmon команду, чтобы определить процесс, который вызывает у вас проблему. Даже если у вас серьезные проблемы с компьютером, прежде чем переустанавливать Windows, лучше попробуйте восстановить целостность установки ОС или для Windows 8 и более поздних версий Windows выполнить команду DISM.exe /Online /Cleanup-image /Restorehealth.

Shell Infrastructure Host — что это за процесс и почему он грузит процессор?
Среди прочих процессов в диспетчере задач Windows 11 или Windows 10 вы можете обнаружить процесс Shell Infrastructure Host или sihost.exe, который при нормальной работе не проявляет себя особенной активностью, но в некоторых случаях заметно нагружает процессор.
В этой статье подробно о назначении процесса, можно ли его отключить или удалить, а также о возможных решениях в случае, если он вызывает высокую нагрузку на систему.
Что делает процесс Shell Infrastructure Host
Shell Infrastructure Host — один из основных системных процессов Windows, который наряду с процессом «Хост Windows Shell Experience» отвечает за отдельные действия по отрисовке пользовательского интерфейса Windows: эффектов прозрачности, вылетающих элементов панели задач в области уведомлений, смену обоев рабочего стола, если для них настроено слайд-шоу.
В современных версиях Windows 10 и Windows 11 этот процесс, как правило, не вызывает высокой нагрузки на процессор и не занимает значительное количество оперативной памяти. При обычной штатной работе процесс Shell Infrastructure Host не должен сколько-нибудь нагружать процессор, за исключением кратковременного подъема на несколько процентов при смене элементов интерфейса, а объем используемой памяти обычно не превышает 100 Мб.
Проблемы с нагрузкой со стороны указанного процесса были типичны для ранних версий Windows 10, в дальнейшем ситуация была исправлена. Однако, в некоторых случаях с этим можно столкнуться и сейчас, что делать в этом случае?
Что делать, если Shell Infrastructure Host грузит процессор
Прежде всего: вы не можете отключить этот процесс или удалить соответствующий файл, при условии, что речь идёт о легитимном файле sihost.exe в папке C:\Windows\System32\. Завершить процесс в диспетчере задач возможно, но он автоматически будет перезапущен.
Если речь идёт действительно о системном процессе Shell Infrastructure Host, следующие действия могут помочь решить проблему с высокой нагрузкой:
- Если в качестве обоев рабочего стола установлено слайд-шоу (или обои Windows: Интересное), попробуйте включить статичный фон. Сделать это можно в параметрах персонализации — нажмите правой кнопкой мыши по рабочему столу и выберите пункт «Персонализация», перейдите в раздел «Фон» и измените настройки.
- Если предыдущий шаг не помог, в параметрах персонализации зайдите в раздел «Цвета» и попробуйте отключить опцию автоматического выбора контрастного цвета (цветового акцента), а также эффекты прозрачности.
- Если до недавнего времени проблема не наблюдалась, можно использовать точки восстановления системы на дату, когда всё работало в штатном режиме, это может сработать.
- Теоретически, использование каких-то твиков или программ для изменения оформления Windows могут вызвать проблемы с работой этого процесса: проверьте, сохранится ли высокая нагрузка, если временно отключить такого рода программы при их наличии на компьютере.
- Обновите Windows, особенно если ранее вы отключали обновления и в течение долгого времени их не выполняли.
- Если нагрузка со стороны процесса возникает только при использовании определенной программы или игры, возможно, речь может идти о каком-то конфликте или утечке памяти (вызванной проблемами с программой, а не с Windows), как правило, при этом в диспетчере задач видно, что количество занятой памяти или невыгружаемый пул в памяти растет без признаков автоматической очистки. Возможное решение — обновить программу, попробовать загрузить её из другого источника.
- При возникновении высокой нагрузки во время просмотра фотографий стандартным приложением «Фотографии», попробуйте обновить приложение, а если это не помогло — перейти к использованию альтернативных программ для просмотра изображений.
- Если файл процесса sihost.exe находится не в папке C:\Windows\System32, срочно проверяем сам файл в VirusTotal, а компьютер — с помощью антивируса и утилит, таких как AdwCleaner.
- Даже если файл — системный и не является вирусом, но наблюдается его странное поведение, проверка на наличие вредоносных программ имеет: вредоносные процессы могут влиять на работу процесса Shell Infrastructure Host.
Еще одна возможность, если к этому моменту проблема сохранилась — выполнить проверку и восстановление системных файлов Windows.

Here are 10 basic security tips to help you avoid malware and protect your device:
Use a good antivirus and keep it up-to-date.
It’s essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.
Keep software and operating systems up-to-date.
Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.
Be careful when installing programs and apps.
Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you’re agreeing to before you click «Next.»
Install an ad blocker.
Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.
Be careful what you download.
A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.
Be alert for people trying to trick you.
Whether it’s your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it’s easy to spoof phone numbers, so a familiar name or number doesn’t make messages more trustworthy.
Back up your data.
Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.
Choose strong passwords.
Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.
Be careful where you click.
Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.
Don’t use pirated software.
Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.
To avoid potential dangers on the internet, it’s important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.
What Is The Shell Infrastructure Host Process And Is It Safe
One of the most important processes, however, is the Windows Shell Infrastructure Host process. While essential, this process can also be behind some system stability issues, such as high CPU usage. Here’s what you need to know about this process and how to resolve any issues with it.
What Is the Shell Infrastructure Host Process and Is It Safe?#
While some system processes (like yourphone.exe) aren’t hugely important in ensuring Windows can run properly, the Windows Shell Infrastructure Host process isn’t one of them. This process plays an essential role in generating several parts of the Windows user interface for users to see and interact with. These include the Start menu, certain visual effects (such as transparent windows), notifications area pop-ups, desktop background slideshows, and more. As Windows relies on its graphical user interface for users to navigate and operate it, few processes are as essential for a working system as this one. If you’re looking at Task Manager, you might spot this process with slightly different names, including the executable file name (sihost.exe). In the end, they’re all the same thing—or should be. While malware is known to hide itself as certain Windows components like sihost.exe, this is pretty unlikely for this particular process. With that in mind, you can rest assured that the Shell Infrastructure Host process is entirely safe to run. If you want to be completely sure, however, you can follow the steps below to check that the process is genuine.
What Causes sihost.exe High CPU, RAM, or Other High System Resource Usage?#
While the Shell Infrastructure Host process is a genuine system process, it isn’t without its problems. In the early days of Windows 10, users reported issues with sihost.exe causing high CPU and RAM usage. Updates and bug fixes have helped resolve this for many, but it could still be an issue. Most of the time, sihost.exe shouldn’t be using much (if any) system resources. The exception to this is when your graphical interface changes in some way. For instance, when you open new windows, change backgrounds, and generally interact with your UI, the sihost.exe will spike with some usage, but it should remain limited.
Troubleshooting sihost.exe High CPU and RAM Issues#
However, if the CPU and RAM usage is unusually high (and maintains high levels of usage), it could point to a stability issue with your PC. While malware could be the cause, it’s more likely that your system is out-of-date. Microsoft regularly issues new bug fixes for Windows to help stability issues like this. If there are available updates, install them and restart your PC to see if it has any impact on your system performance. If updates haven’t resolved the issue, you may need to look at checking your PC for corrupt system files which could affect your system performance. The SFC tool will take some time to complete. If it can’t repair your system, you may need to look at alternatives to resolving this issue, such as resetting Windows 10 to factory settings.
Checking Whether the sihost.exe Process Is Genuine#
It is reported that some types of viruses and malware try to disguise themselves as legitimate system processes. As the security of Windows improves, this is becoming less and less likely, but it isn’t impossible. While the Shell Infrastructure Host process is unlikely to be malware in disguise, you can check for your own peace of mind using the Task Manager. Like other major system processes, the genuine Shell Infrastructure Host file (sihost.exe) is located in the C:\Windows\System32 directory. If Task Manager opens to another location, you can be certain that the file running on your PC isn’t genuine. If that’s the case, you’ll need to stop using your PC and immediately scan for malware to make your PC safe to use.
Can the Shell Infrastructure Host Process Be Disabled?#
As a major system process, the Shell Infrastructure Host process isn’t something that you can disable or remove from a Windows 10 installation. Attempting to stop sihost.exe will cause your PC to freeze, cause a blue screen of death, or randomly restart. This process is required for Windows to run effectively, so you can’t switch it off or remove it. You can, however, clear some system memory to help free up vital resources for this process and other system processes. There are several ways you can do this, including clearing the Windows memory cache and reducing the number of active programs running on your PC at any one time.
Further Troubleshooting For sihost.exe Issues#
If the Windows Shell Infrastructure Host process is still causing problems, you’ll need to troubleshoot it further. Windows will reserve some system resource usage, but if it’s using a lot of CPU or RAM, it points to wider issues with your system performance. One way to ensure that your system is healthy is to start again by wiping and reinstalling Windows. You should then keep up with regular system maintenance, including keeping Windows updated and removing any malware. Of course, you may need to consider upgrading your PC if your PC is becoming too slow to use.
