In Windows 7, if QQ is enabled after startup, the IE browser will display a white screen. The menu bar will be all white. Opening any web page will be blank and will appear, "Compatibility View caused by this webpage problem ........... ", it takes a while for the browser to restore the response.
This situation occurs only after QQ is started. It must have been caused by conflicts between QQ and IE browsers. Then try to uninstall the latest version of QQ2013 and reinstall the previous version, but the problem still occurs.
Next, I tried to disable GPU hardware acceleration for IE and use SFC for restoration.
Later, it was found that this problem did not occur if you right-click and select "run as administrator" in IE. Is this a permission issue? Isn't it the highest permission after logging on to the system?
Then I tried to delete the original account and enable the administrator account to solve the problem. I think the problem was caused by the system permission problem. Many people have encountered the problem of system account permissions: the administrator account you are creating cannot obtain the highest permission, but the administrator account can.
