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.

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 cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.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: Security 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. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
