Delivery optimization what is this folder? What to do if "Service Node: Local System" is loading the system

On Windows 10 and earlier versions, when working, you may notice sudden OS freezes, lags, and incorrect operation of applications. An experienced user will immediately think that in Windows some process loads the entire OS, although a separate component can also load: HDD, processor or memory. As an example, let's look at “Service Node: Local System”, which loads disk, memory and even the network.

The problem itself can be easily detected in the task manager. Open it using the combination “Ctrl+Shift+Esc” and see what is loading the disk, processor or memory.

Service Host: Local System has other processes in its set that disabling or restarting may resolve the issue. These are the processes:

Update centre– when downloading and installing updates, the likelihood of a load on the disk will be high, so this option is worth checking;

SuperFetch– optimizes Windows operation for more quick launch software. A possible process failure could lead to increased load on components (Read:);

Push notifications– these are notifications that appear on top of all open windows, even when the application is disabled. Windows 10 also has this option. For some, disabling the service helped get rid of the problem.

Service node: local system loading disk

The easiest way to get rid of problems in Windows is to restart the computer, after which the configuration components should no longer be loaded. If you've already done this, then the problem is a little more serious. Let's move on to the following method:

Stopping the above services

To avoid searching for services manually, you can use short commands. To do this, open an elevated command prompt and enter the following phrases to disable Push Notifications, SuperFetch and Update Center services:

net stop wpnservice
net stop system
net stop wuauserv

If you notice that the loading process has stopped and the system began to work smoothly, then the reason was indeed in one of these services. Unfortunately, this effect is temporary, as after restarting the computer the problem may reappear. To prevent this from happening, you will have to disable startup manually:

Press the combination Win+R to open the “Run” window and enter the command services.msc to enter the services section;
We are looking for SysMain services, Update Center and SuperFetch;
In the properties of services in the “Startup type” section, use the parameter "Disabled" and apply the changes.

If this does not help solve the problem, try using the Process Explorer utility. It shows the current processes that load the system the most, so it will be very useful.

Returning the system to a restore point

This method makes sense if the existing restore point was created recently, a maximum of a week ago. To get to the recovery partition, in Windows search enter "Recovery".

Select the option and follow the instructions in the window.

Service node: local system loading disk, loading network and memory

This problem can become a problem not only for disk media, but also for the network and RAM. If the problem is in the network, then there is some service that “eats” a lot of traffic; if there is a problem with RAM, it is possible that there is some program or service in the background. In the first case, this is relevant for the Update Center, which can constantly download something and sometimes disabling it is problematic. In any case, if you can’t solve the problem, there are a couple of tips.

Recovering system files

Run the Command Prompt utility with elevated privileges and enter the command to restore the system image:

DISM.exe /Online /Cleanup-image /Restorehealth

After the previous command has completed the process, enter a friend who checks the OS for damaged files:

sfc /scannow

After completing the process of these tools, restart the computer. We observe in the task manager how the components behave, whether they are loaded or not.

Cleaning the SoftwareDistribution folder with updates

If the result is negative, immediately enter command line following:

net stop wuauserv
net stop bits

We restart the computer, and then, still in the same command line, start the disabled services:

We have looked at many options to help you get rid of disk loading, random access memory or Internet to maximum values due to the Service Host Local System service.

A similar situation can be observed by almost any user of a modern operating room. Windows systems 10, which does not have . The Internet connection is especially actively used by the delivery optimization service in the first minutes after Windows installations 10. Why this happens and what to do about it you will learn from this article.

What is the Host: Delivery Optimization service responsible for in Windows 10?

A service with a similar name can also be found in Windows 8.1. It is responsible for downloading system updates. This is why in the task manager you can see how it is actively “eating” your Internet. At this moment, sites load more slowly, and downloading of any files is also slow.

Immediately after installation, Windows 10 begins to actively download system updates, bringing its state up to date. The installation of drivers for all devices on your PC also begins.

Usually at this moment you can see high activity in the same task manager Windows services Modules installer worker, which is directly responsible for installing downloaded updates.

"Windows Modules installer worker" service activity

But not only after installing Windows, increased activity of these system services is observed. Several times a month, during the release of system updates, they also make themselves felt.

What to do in this situation?

The answer to this question is simple - nothing, just give your computer time to download these updates. He is in automatic mode will download the update files and install them. After this, the activity of the delivery optimization node service will drop and it will stop eating up the Internet.

Delivery Optimization Service Activity

The time required for this depends on the performance of the computer and the speed of the Internet. The higher they are, the faster the updates will be installed.

Conclusion

Windows 10 is by far the most current and updated system. The developers are constantly improving and finishing things in it.

Host service: delivery optimization in Windows 10 eats up the Internet due to downloading system update files. This happens when updates are released, which can happen several times a month.

You don't need to do anything about it. You just have to wait until this service ends, after which its activity will drop and the Internet will start working at the same speed.

The update system in the operating system is based on P2P technology and operates on the principle of a torrent client. Such a system is called Delivery optimization Windows updates (Windows Update Delivery Optimization- WUDO).

Windows Update Delivery Optimization allows you to receive Windows updates and applications from Microsoft Store from sources other than just Microsoft servers, such as other computers in local network and computers on the Internet downloading the same files. Delivery Optimization also pushes updates and applications from your computer to other computers on your local network or the Internet.

When downloading updates or applications while using Delivery Optimization operating system looks for computers on your local network or the Internet that have already downloaded this update or application. Windows does not download the entire file from one source. Instead, the download is broken into several smaller parts. Windows then gets some parts of the update or application from computers that already have it, and gets other parts from Microsoft servers. Windows uses the fastest and most reliable download source for every part.

This feature creates a local cache and saves downloaded files to given cache for a short period of time.

Delivery Optimization cannot be used to download or share personal content. Delivery Optimization does not access your personal files or folders and does not modify any files on your computer. Delivery Optimization downloads the same updates and apps you would get through Windows Update and the Microsoft Store.

Windows update delivery optimization is implemented only in the Home and Pro editions, and is not available in the Enterprise and Education editions for security reasons.

By default, Delivery Optimization is enabled and allows you to send updates and applications from your computer to other computers on your local network or the Internet.

To prevent Windows 10 from sending updates to the Internet, open " Windows Settings", to do this, click on the taskbar button and select or press the key combination + I

In the Windows Settings application window that opens, select a category Update and Security

In the window Extra options click on the link Delivery optimization

In the window Delivery optimization, you can completely disable sending updates by checking the switch Allow downloads from other computers to position Off, or enable exchange of updates only with computers on the local network by selecting the appropriate radio button.

Now Windows will not send updates to the Internet.

If you are on a metered or restricted Internet connection, Delivery Optimization will not automatically download and send parts of updates or applications to other computers on the Internet.

Windows 10 introduces Delivery Optimization Service, which allows you to quickly receive system updates and download applications from the Microsoft Store. The optimization service works on the p2p (peer-to-peer) principle, allowing you to download a large update in parts, from different devices.

If the Delivery Optimization Host Service is loading the Internet, you can simply disable it. In this case, updates will only be downloaded directly from Microsoft servers, and the speed (network load) will decrease.

Torrents work on a similar principle, downloading large amounts of data from tens or hundreds of computers simultaneously. If the connection is weak, this download format will heavily load the Internet - even the browser may stop working fully. On weak devices, high write speeds will also load the processor and hard drive.

Disable Delivery Optimization

Disabling Delivery Optimization will prevent Windows 10 from downloading updates and apps from the Microsoft Store from other computers, including computers on your local network. Microsoft servers will be used to download all updates.

To disable the Delivery Optimization Host service:

Click "Start", select item "Options".
Choose "Update and Security".
Go to tab "Extra options", then open the service "Delivery Optimization".
In chapter Allow downloads from other computers turn the switch to position Off.

After these steps, files will no longer be downloaded from other computers and sent to them. Downloads will only occur from Windows and the Microsoft Store, while the delivery optimization functionality will continue to work. This should be enough for the service to stop loading the Internet, and along with it the processor and memory (hard drive).

In the Delivery Optimization section, you can also choose from which sources your computer will receive files: "Computers on a local network" or “PC on the local network and PC on the Internet”. Should choose first option so that the system does not send updates and applications to other devices with Windows 10, and also does not download anything from them.

Limited and limited network connection

When using a limited or limited connection to Internet Windows 10 will not send updates or application files to other computers, nor will it download them. This is done in order to save metered or expensive traffic: for example, when roaming abroad. Windows will not do this automatically; you need to configure the appropriate network settings to disable the Delivery Optimization Host service for specific Internet connections.

Set metered connection on Windows 10 you can do this:

Press the button "Start".
Select item "Options".
Go to section Network and Internet -> WiFi.
In the window that appears, select the network for which you want to disable delivery optimization.
Enable option “Set as metered connection”.

Please understand that these steps will disable downloading files from other computers for only one selected Internet connection. If the computer is connected to another network, the next update download will also begin to load the Internet and the system.

For this reason, it is recommended to completely disable the service (if it really interferes with your life), since the only payment for this will be the low speed of downloading system updates and applications from official store. It can also be used to optimize performance. Together with a registry cleaner and programs like CCleaner, the system performance boost can be significant.

When Delivery Optimization Doesn't Work

The Windows 10 Help does not contain comprehensive information about the operation of the delivery node, including on the official Microsoft website. Typically the service runs constantly, uploading or receiving files in the background. During the rollout of global updates, when packages of files are downloaded to many millions of devices, the load on the network can be colossal.

Even if the user has not turned off the service, Delivery Optimization will stop working in the following cases:

When operating on battery power. The process of sharing and downloading files increases energy consumption, so on laptops and other portable devices, when running on battery power, the service is disabled.
On a limited connection. File sharing is stopped to save traffic. The classic situation: a laptop with Windows 10 is connected to a smartphone that distributes limited mobile Internet via Wi-Fi.
Windows 10 Mobile. Accurate data about mobile version It was not possible to find 10s, but it is very unlikely mobile devices Delivery optimization will work. This is due to the need to save memory, device charge, and mobile traffic.
When there is no disk space. For stability and high speed of file exchange, part of the data is cached. In the early Windows versions 10 this sometimes led to excessive cache growth, but the problem was later fixed. If the computer is not enough free space on disk for caching, the delivery node optimization service will stop and file uploading/downloading will stop.

In conclusion, we advise you to disable this service if, for any reason, it loads the network or disk and interferes with full operation. There will be no disadvantages due to this, since a weak Internet will still not allow you to download the update really quickly and without harm to other functions of the PC.

Greetings. Delivery Optimization this is part of the name Windows Update Delivery Optimization- some technology for receiving updates ( system function) not from official Microsoft servers, but from other verified sources (or network hosts). Sources mean trusted nodes on the Internet and regular computers on your local network. This type updates help save power on Microsoft servers. Windows 10 has a setting for this technology.

As Microsoft itself says, today an update package can weigh quite a bit, and to optimize delivery they have created Delivery Optimization technology. Which is quite logical - why download patches from the Microsoft server when your neighbor already has this update. This process is completely confidential and is controlled by internal processes in Windows. No personal or personal information not transmitted, this is excluded.

Therefore, it is logical to assume that Delivery Optimization This is the folder for downloading updates not from Microsoft servers, but from other secure sources.

Support for Delivery Optimization technology (also called update delivery service)

Do I need to delete the folder?

My thoughts:

The Delivery Optimization folder contains patches that must be removed after use or when they reach a certain size. If Windows does not delete this data, it is possible that it is being used or will be needed in the near future.
As a last resort, you can clean the system of temporary files, including patches that may take up space on your hard drive. To do this, hold down Win + R and insert the cleanmgr command - after which a selection window will appear, select system. Next, find the checkbox for updates, check it and clean Windows.
In a situation where a folder takes up an impressive amount of space, tens of gigabytes, but there is no way to delete it, despite the fact that updates are disabled or do not work. In this case, you can use an extreme deletion method - the Unlocker utility, which is specifically designed to destroy undeletable/locked files or folders. When installing the utility, do not forget to uncheck the Delta Toolbar, otherwise this advertising toolbar will be installed.

The folder is located here:

C:\Windows\SoftwareDistribution\DeliveryOptimization

Before cleaning the folder, you must disable this technology. You may need to disable the update service.
