No connection with IE10 to https-sites
I somehow managed it to disable secure connections with IE10. In Internet-Options - extended, all settings concerning these connections are greyed out: use SSL2, SSL3, TLS 1.0, 1.1, 1.2.
A reset on any of the two buttons at the bottom of these settings doesn't change this (I use the german version of IE10, so I don't have the exact names in english)
When I try to open a secure page with IE10, I get the message "This page can't be displayed".
I have no problem to access https-pages with Firefox 24.0 or Opera 16, it must be something IE-specific; I might have disabled something I shouldn't, but I can't find the culprit.
I hope I don't have to re-install Win7. (Win7 Ultimate, SP1, 64-bit)?
Thanks for any help
