“Service node: local system” loads the system: causes of the problem and possible solutions

PC performance is a criterion positioned by users as one of the most important aspects in the operation of a computer device. And indeed, few people can positively characterize the operation of a computer if the device often hangs, slows down, does not respond quickly to requests. In such situations, users try to solve the problem in a variety of well-known ways, for example, to optimize the work of the laptop through the resources of special utilities, or to close irrelevant programs running in the background. Often, these methods of struggle save from freezing, however, there are situations when the user has to look for a problem after performed operations deeper, because of their inefficiency. Most users know that all tasks loading OS can be calculated, as well as deactivate unnecessary ones using the Task Manager service. In a situation where large-scale resources are loaded through the fault of the Service Node: Local System module, it is almost impossible to specify which service is the culprit for the precedent. In this article, we’ll tell you what the user should do if his PC began to work slowly and stopped responding promptly due to the high resource consumption caused by the node.

Eliminating system boot local service.

What is this process: the essence of the problem

The essence of the problem lies in the fact that unlike situations when a PC hangs due to a large number of background processes or programs that are blocked by simply selectively deactivating, a precedent when the OS is loaded with local system services that include many components does not imply such technical opportunities. A conditional node is a process that includes a set of various services necessary for the correct operation of a PC, services that are loaded when the device is started up or the specific utility is activated. The resource consumption of the process can be assessed in the Task Manager, however, it is impossible to find out the specific element of the node loading the OS. Disabling this process through the dispatcher’s tools does not solve the problem at all: at best, the contractor will encounter a repeated, automatic restart of the process after restarting the PC, at worst, cause and effect serious malfunctions and lags in the functioning of the device.

Yes, and it is impossible to technically block all OS-loading components of a node, since the components of a module, due to their systemic nature, are duplicated in other procedural categories. It is noteworthy that such precedents are more characteristic of computers running Windows 10: earlier OS variations are less susceptible to this kind of problems. Naturally, faced with a situation where local operation services load a device, consume more than a quarter of CPU resources, the user will have to look for ways to fix the problem. Over time, the load on the OS will only increase, which will result in the inability to effectively operate the device according to personal needs and needs, therefore, it is desirable to address the problem immediately, using effective methods to optimize the process, which we will discuss in detail later on in the article.

Disk Load: Problem Solving

A detailed study of the operation of the “Service Node: Local System” module in the dispatcher's parameters often shows that the highest load indicators fall on the disk. If the user had to deal with such an expression of precedent, then you can solve the problem by simply restarting the laptop. This option rarely helps to solve cardinal problems, however, in situations where the precedent has a one-off nature, the restart process automatically closes irrelevant applications and functions, which reduces resource consumption. If, after a reboot, the problem does not withdraw itself, the computer continues to boot for a long time, it is worth moving on to more effective methods of solving the problem. To help cope with the precedent when the “Service host: local system” loads the Windows disk pretty much, can an elementary, temporary shutdown of the antivirus program. The procedure is performed as follows:

  1. To begin with, we disable the antivirus utility that is completely used on the laptop, which often loads the device with powerful protective parameters.
  2. We check the load in the Task Manager.
  3. Go to the parameters of anti-virus software, disable the automatic, simultaneous launch of the protective utility with the boot PC.
  4. Reboot the computer device and check the load on the disk.

If the problem persists, try checking your PC for viruses from one of the reliable utilities by downloading it from a trusted resource, or better yet, from the developer’s official website. When options with incorrect work of the protective utility and virus infection of the PC are excluded, and the problem is not solved, the question is to try to solve by one of the following methods.

Suppression of irrelevant services

Since the reasons why there are loads on the disk from the “Service Node: Local System” configuration are not determined by theoretical methods, you can try to eliminate the problem by practically turning off the conditioned operations. To begin with, we perform the shutdown of the following services by the automatic method, via the command line, by introducing administrative instructions and confirming them:

  1. Register the phrase Net Stop VPNservice, which allows you to disable the service node responsible for push notifications.
  2. We enable the installation of Net Stop Sysmain for Windows 10, or the prescription of Net Stop SuperFetch for earlier variations of Windows. In fact, these processes are designed to speed up the loading of applications on a PC, however, their work is conditionally necessary, and very often loads the processor with unnecessarily large-scale consumption of resources.
  3. We disable the local system's node module, which supervises the work of the Update Center, by activating the Net Stop Wuauserv decree.

After confirming the commands, check whether the problem node further loads the disk. If the resources consumed by the services of the complex with the name “Local system” returned to normal, then the precedent was triggered by one of the above processes.

However, at this stage, the work should not be considered completed, since the problem can be reactivated after the next restart of the device. In order for the precedent not to be repeated systematically, after each turning on the laptop, you will have to manually turn off the conditioned processes according to the following regulations:

  1. Open the "Run" window by pressing the key combination Win and R.
  2. Enter services using the introduction of services.msc.
  3. Find the components of the Update Center, Sysmain and SuperFetch components in the service registry.
  4. Alternately inspect each node and deactivate its operation by assigning the “Startup type” option to the “Disabled” property.
  5. Confirm the changes made by pressing the “OK” button.

The executed manipulations will be able to guarantee the blocking of the loading processes, which will allow no longer worrying about their impact on the efficiency of the PC.

System rollback to optimal point

Often, the standard system rollback helps to solve the problem until the PC operation did not cause any complaints about its efficiency from the user. This method, however, can be used only in the situation if there is a recently created restore point, and its formation precedes the onset of problems with the performance of the device. To perform the task, simply open the “Restore” item, where you activate the “Start System Restore” feature and, following the system prompts on the screen, return the OS status to a known working moment. The method works in cases where the conditioned loads began after user intervention or installed programs in the OS catalog or settings.

Methodology for removing load on memory and network

If the above manipulations did not give an effective result, it is possible that a factor according to which the “Service node: local system” tupit and loads the CPU is not the excessive activity of the services, but the defectiveness of the files used as basic for the OS. Such a precedent can manifest itself against the background of long-term use of files, with maximum user activity, if various heavyweight programs and applications are often installed on the PC, including games that have the legal priority to change and edit system tools, folders and their contents. It is possible to eliminate such a scenario by means of restoring the system in an automated way, or in manual mode, if the first method failed.

System file recovery

Since the “Service node: local system” consists of a set of simultaneously functioning operations, increased processor loads can be caused directly by errors in the base system files, due to their movement, deactivation, unauthorized damage by the user or specific system utilities. To remedy the situation, troubleshoot in this case, you can try through the use of the system resource DISM, providing the ability to service the deployment images, with parallel management of them in an automated mode. The procedure for the procedure consists in the following manipulations:

  1. Activate the "Command Line" with administrator privileges.
  2. Register and confirm the directive DISM.EXE / Online / Cleanup-image / Restorehealth.
  3. After the process finale, write the well-known sfc / scannow directive that starts recovery mode.

After the recovery procedure, you need to restart the laptop, and check the result. If the “Service Node: Local System”, despite the recovery operations, loads the PC further, it is worth trying to remove the load on the OS by means of similar manipulations by doing them in a manual format.

Cleaning the update folder

In a situation where the automated performed restoration manipulations did not give the desired result, the resulting processes continue to load the network or RAM, it is worthwhile, to fix the problem, to use the resource capabilities of the “Command Line”.

To begin with, the user's task is to call the “Command Line”, where it is necessary to enter and confirm Net Stop Wuauserv and Net Stop Bits, which cause the Update Center and background file transfer processes, respectively, to enter and confirm. Next you need to go to the Windows system folder, go to the distribution called Software Distribution and delete all its contents: both file documents and installed applications. The components of this folder are often automatically controlled by the system, however, in some cases, certain problems from the category, when the “Service node: local system” slows down the laptop and loads the memory, are solved by cleaning the distribution package in manual mode, which will optimize the PC.

After freeing up space on the hard drive, deleting everything that loads the Internet and memory resources, you will need to restore the functionality of the Update Center and the Bits module by entering Net Start Wuauserv resolution and Net Start Bits directive in the Command Line. The executed manipulations almost always give a 100% result optimizing the resource-consuming capacity of the “Service node: local system” complex.


This article discusses options for resolving the issue of high-impact parameters of the local system's node services on the performance of a computer device, aimed at minimizing the load of memory and the Internet, and at adjusting the load on the disk.

Remember to regularly monitor the state of the computer, systematically cleaning its contents from unnecessary components and unexploited applications - these are factors that minimize the likelihood of a decrease in PC productivity. As an excellent tool for regular monitoring of executive processes on a computer, you can also use special programs, for example, to download and install, after fixing a problem, an effective and reliable utility Process Explorer, which allows you not only to find a loading component, but also to block it unprecedentedly precedents of the category under discussion.
