Suddenly at start of Google Chrome (installed month’s ago) Windows 7 show the request UAC (User Access Control), indicating that this program will try to start with administrator rights. Probably due to update of Chrome or more likely one of his plugin, must have changed some parameters and Windows, rightly, he notice me a possible danger like a virus or trojan. Knowing that the version installed (and reinstalled for safety) is healthy, I tried a quick workaround. First I found the executable, which usually is not in the classic c:\Program Files but under your user account:

C:\Users\YOURUSERNAME\AppData\Local\Google\Chrome\Application\chrome.exe

So “classic” right click chrome.exe property. From the screen that comes out press on compatibility and then at the bottom you will find the button “change settings for all users“.
A new window appears, after all, de-select option “start this program as administrator“.
Give OK to close all windows, and the problem is finally solved.
