What is UsoClient.exe in Windows 11/10

Written by Robert Bailey

If you notice a CMD popup of UsoClient.exe every time Windows 11/10 starts, this post will address some of your questions. Is Uso Client a virus or a system process?

The acronym USO stands for Update Session Orchestrator. The Windows Update Orchestrator, represented by the usoclient.exe file, is located in the System32 folder. When you navigate to this folder location, right-click on the file, and select Properties, you will observe that it is a process belonging to the Microsoft Windows Operating System, with a size of 19.5 KB. Windows 10 utilizes usoclient.exe and its associated processes and files, including usocoreworker.exe, usoapi.dll, usocoreps.dll, and usosvc.dll, to perform tasks such as checking for, downloading, and installing Windows Updates. These processes fulfill the functions that were previously handled by wuauclt.exe.

Scans conducted by VirusTotal confirm that the file C:\Windows\System32\usoclient.exe is completely clean. Therefore, if you encounter a file with the same name in any other directory, it may potentially be a virus. In such cases, it is advisable to run a scan with Gridinsoft Anti-Malware to ensure the safety of your system.

What is Usoclient.exe process?

The legitimate usoclient.exe file, associated with the Update Session Orchestrator in Windows, is typically located in the System32 folder. However, if you come across a file named usoclient.exe in the temp folder, it is highly likely that it is a virus coin miner. This malicious software aims to utilize your computer’s resources for cryptocurrency mining without your consent or knowledge.

It is crucial to take immediate action if you encounter usoclient.exe in the temp folder. Run a thorough scan with Gridinsoft Anti-Malware to detect and remove the virus coin miner. Additionally, consider implementing strong security measures and keeping your operating system and antivirus up to date to prevent such infections in the future.

Usoclient.exe – Very high CPU as well as GPU usage

Besides CPU utilization, some of the coin miners also use GPU power for their tasks. In that instance, you will probably struggle also to see the mouse arrow moving – GPU is often utilized on 100%. It is not as crucial as processor for system work, so Usoclient.exe coin miner viruses do not waste time on trifles and utilize all of it. It often can result in bad consequences.

Shortly about cryptocurrency mining

Crypto mining term means the operation of calculating the transaction block hash. That is a integral part of any project based on the blockchain technology. Since this action takes a lot of calculations, a high-end PC is required. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptocurrency mining farms usually consist of dozens of graphic cards to complete their task efficiently. Such computer systems are not usable for “usual” purposes, like gaming or web browsing. Crooks who gain money via this coin miner use someones’ hardware instead, even if they are used for the regular activity.1

List of the typical coin miner symptoms

  • Microsoft Defender is stopped;
  • CPU and GPU is loaded at 80-90% exactly after the system start
  • Cooling fans are running at high speed and create a lot of noise
  • A single process in Task Manager consumes all CPU and GPU power
  • How dangerous is the Usoclient.exe miner?

    First of all, Usoclient.exe virus makes your computer overloaded. It is unable to run your applications now, as all CPU power is consumed by a malware. That malware does not care for your necessities, all it focuses on is generating profits on you. Even if you are patient, and you waited until browser is open, you will likely struggle with incredibly sluggish efficiency. Pages will open for years, any sort of logins will likely take about a minute – just a headache for a person who does a job online.

    “Visible” harm is not a solitary negative thing coin miners perform to your computer. Usoclient.exe coin miner also deals damage to your operating system. To execute all malicious operations properly, it wrecks the protection mechanisms of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent detection. If you open the HOSTS file, you will likely see a number of new notes – they are brought in by this coin miner to connect your system to a malicious mining network. All these adjustments are about to be gone back to the initial state in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides slowing down your PC, running at peak power for a long period of time may trigger damage to your machine and raise power costs. Hardware elements are designed to easily deal with high load, but they are good with it only in case when they are in a good shape.

    Little and covered processor fan is quite hard to broke. Meanwhile, graphic cards have big and easy-to-access fans, which can be easily broke if touched while working, for example, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the unusually high load caused by Usoclient.exe miner can easily lead to graphic card failure2. Video cards are also tend to have increased wearing when used for crypto mining. It is likely an undesirable situation when the performance of your video card decreases on 20-30% just after several weeks of being used in such a way.

    How did I get Usoclient.exe coin miner virus?

    Coin miners are the most common malevolent programs through “major” malware. Adware frequently works as a carrier for Usoclient.exe malware infiltration: it shows you the banners, which contain a link to malware downloading. Sure, this abstract “malware” can belong to any type – another adware, spyware, rogue or backdoor. However, the statistics show that around 30% of all malware spread through the malevolent banners are coin miners – and Usoclient.exe is just with them.

    An additional way you could get this item on your PC is by downloading it from the dubious website as a part of a program. People that spread hacked variants of favored programs (which do not demand the license key) have small chances to get paid. For this reason, there is a very big temptation to add malware to the final package of the hacked application and get a coin for every setup. Before blaming these guys for hacking and malware spreading, ask yourself – is it okay to avoid purchasing the program in this manner? It is more affordable to pay $20-$30 one time than to pay a much greater sum for antivirus software and new parts for your desktop.

    How to remove the Usoclient.exe miner from my PC?

    Removing such a virus involves using specific tool. Proper antivirus should have high performance at scanning and also be lightweight – in order to create no problems with utilization also on weak PCs. On top of that, it is better to have proactive security in your security solution – to halt the virus even before it starts. Microsoft Defender lacks these elements for different reasons. That’s why I’d suggest you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is a great choice that fits each of the specified characteristics.3

    Before the malware removal, it is important to boot your system into Safe Mode with Networking. Since Usoclient.exe miner takes a lot of processor power, it is needed to halt it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.

    Booting the PC into Safe Mode with Networking

    Press the Start button, then choose Power, and click on Reboot while holding the Shift key on the keyboard.

    Boot into Windows Safe Mode

    Windows will reboot into recovery mode. In that mode, choose Troubleshoot→ Startup Settings→ Safe Mode with Networking. Press the corresponding button on your keyboard to choose that option.

    When your computer is in Safe Mode, all third-party applications, along with the majority of non-critical operating system components, are not launched with the system start. That gives you the ability to clean the PC without dealing with high CPU usage of the coin miner.
