UIUCU is a utility from Conexant, a company that makes various PC components including sound devices. If you install drivers for a hardware component made by Conexant, it is likely that this utility will be added to your startup routine. Nevertheless, disabling it hasn't proved to be problematic in unstressed systems.
for user hive profile clean up / delete out of HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
I don't think this is so clean and safe as this writeup would lead one to believe. While I don't think it's malicious, it keeps popping up every 20 minutes or so with a dialog informing me that the driver installation is complete (I've installed NO new drivers for weeks now).
I downloaded this when attempting to reinstall sound drivers on HP Compaq v2000 laptop. Pop up window shows visible drivre file by name that was loaded sometimes. However window also repeatedly pops up mutiple times showing no file name, and may be loading system/hidden os files that are malicious. Once after appearing in session, email password failed to work.

Best practices for resolving uiucu issues

A clean and tidy computer is the key requirement for avoiding problems with uiucu. 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 uiucu.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.
