Hey guys, I have a problem with Internet Explorer and cookies/cache (IE 11 on Win 10 and WinServer 2012). FYI: For now I have to use IE and Windows, because my software is only working with these, so no chance of using Firefox or Chrome. The problem: I use proxies for creating accounts on a website. This works often fine, but then I get asked for a captcha, which indicates that I was "detected". From then on, switching proxies has no effect, because somewhere seems to be a cookie left in IE. If I switch to Chrome (manually) it works fine on the same proxy. So it must be an IE issue. What I tried: IE Settings to clean cookies/cachs and everything else on exit. Command Line: RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 255 (in low integrity level) Command Line: delete all files in folder " C:\Users\USERNAME\AppData\Roaming\Microsoft\Windows\InetCache" For some reason, there is still something left, and I have no idea what or where. Any suggestions on how to clean cookies and cache 100% on Windows/Internet Explorer?
