I have to download something and do not want someone accidentally close the window, but at the same time they could have time to use Google Chrome, so if you have an answer if post, please!

This is not the answer you are looking. It's just something you can try. Maybe you can use. "Use multiple profiles" Copy shortcut to Google Chrome. Mine looks like this: "C: \ Documents and Settings \ Username \ Local Settings \ Application Data \ Google \ Chrome \ Application chrome.exe \ "Add the following to: (modify to your taste.) User-data-dir = "C: \ My Folder \ My Documents \ My Chrome" It should now look like this: "C: \ Documents and Settings \ User Configuration \ local \ Application Data \ Google \ Chrome \ Application \ chrome.exe "user-data-dir =" C: \ My Folder \ My Documents \ My Chrome "Change the icon new shortcut. Change the name to something else. Now when you run this shortcut, a "new" Chrome will begin. Everything in this, stay there. Chrome will not affect the running from the shortcut normal. In other words: if you install or add bookmarks Chrome extensions, only available in Chrome. chromium standard is not going to get those extensions or bookmarks. All that "cross" is days. There is no doubt that Chrome is updated. Both will be updated since both run the same exe. Chromes can also run these two together. Each one is totally independent of each other.
