Chrome allows you to manage whether unwanted pop-up windows appear. Pop-up windows that are opened when the end user clicks a link are not blocked. If you enable this policy setting, most unwanted pop-up windows are prevented from appearing. If you disable this policy setting, pop-up windows are not prevented from appearing. If you disable this policy setting, scripts can continue to create pop-up windows, and pop-ups that hide other windows. Recommend configuring this setting to ‘2’ to help prevent malicious websites from controlling the pop-up windows or fooling users into clicking on the wrong window. If you do not configure this policy setting, most unwanted pop-up windows are prevented from appearing. If this policy is left not set, 'BlockPopups' will be used and the user will be able to change it. 1 = Allow all sites to show pop-ups 2 = Do not allow any site to show pop-ups
