What is UNS.exe?

The genuine UNS.exe file is a software component of Intel® Active Management Technology by Intel Corporation.
The User Notification System (UNS.exe) was introduced in Release 7.0 of Intel® Active Management Technology (AMT) to replace “atchk.exe” for showing a system tray Privacy Icon and a popup screen at startup, indicating whether AMT is present and active. In Releases 7.x and 8.x of AMT it also routes application messages using special port numbers to AMT and records alerts from AMT in the OS system log. (These functions became the Local Manageability Service (LMS.exe) in Release 9.0.) “UNS.exe” can be disabled by changing its startup status in “msconfig,” although this may affect interaction of the Windows OS with the AMT ME processor that allows an enterprise system administrator remote access to diagnose and repair the local system, even when inactive.

User Comments

UNS.exe is a process from Intel Corporation and part of Active Management Technology User Notification Service. This process can be closed to free up resources. The UNS receives messages from Intel AMT and write them to the local OS event log for the purpose of notifying end users of predefined events such as when critical System Defense policies are applied by the ME Firmware. The service is meant to be run as a daemon. Messages from the service will be sent to the system syslog. All UNS messages will be marked with a source of "Intel® AMT".

I have it in C:/program files/(x86)/intel/intel® management engine components/UNS/UNS.exe and AVG 2011 gives an alarm on it. I believe it's false positive. After update an alarm disappeared.

Only recently has it appeared in my Windows 7, and when i remove it nothing happens. So at best it's just a digital mosquito. More Microsh*t.
It constantly interrupts my QB POS program and I have to go in and shut it down. I am going to remove it.
Just hangs there and eats your precious cpu.
On my 64-bit Win7 system (4th-gen i7), the size is reported as 363,000, and it runs for a few minutes on startup.

My Single Sign On product was being disabled, Imprivata Support pointed at the UNS service generating some winhttp activity as the cause. I recently had another customer disable UNS.exe to address performance issues and I was wondering if you'd be willing to test with UNS.exe disabled. It is an offering from Intel(R) Management Engine Components or Intel(R) Management Engine and I don't believe it's a critical for operation. Jeong

Best practices for resolving UNS issues

A clean and tidy computer is the key requirement for avoiding problems with UNS. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the UNS.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
