IE 11 renames files. For instance, .exe files become _exe, .zip become _zip. This is happening on Win 7 Ultimate-64-bit, Win 7 Pro 64-bit, and Win 8.1 Update.
This interferes with my ability to get updates to my Visual Studio and many other programming tools.
IE 11 won't even support the Akami system used by MS.
As far as I know all the security settings are set to allow downloads. Windows Firewall is configured to tell me when it blocks a program.
I read an earlier blog post from the IE Team that says this problem is due to some sites being creative!?!
The latest Firefox has no issues downloading.
