If you get a usoclient.exe popup every time you start Windows 10, then this post will answer a few of your questions. Is Uso Client a virus or system process? Well, actually since the last few weeks I used to see a command prompt windows snap open and shut immediately, every time I booted my Windows 10 computer. But it was only yesterday, that the window stayed open long enough for me to note down its name, but not long enough for me to take a screenshot.
If you too are noticing this on your laptop, here are a few things you may want to know.
The usoclient.exe file or the Windows 10 Update Orchestrator, is located in the System32 folder. If you open this folder location and right-click on it and select Properties, you will see that it a Microsoft Windows Operating System process 0f size 19.5 KB.
VirusTotal & Jotti scans find this file C:\Windows\System32\usoclient.exe to be completely clean.
It you find a file with this name in any other folder, it could well be a virus and you may want to run your anti-virus software scan, to be sure.
If you open Task Scheduler and check the scheduled tasks at Microsoft > Windows > UpdateOrchestrator, you will find mention of this process.
The Triggers for this task to run could be One Time, At system startup, Custom Trigger or On an event – and it performs a scheduled Windows Update scan.
In any case, seeing a CMD windows popup on every boot is not good user experience, and I really have no idea why it should be happening on one of my Windows 10 laptops and not the other 3-4 computers.
Those of you who may still be concerned, may want to check you firewall and router logs for the connection requests it makes.
Feel free to add any additional information or feedback you may have about this.
