In 64-bit Windows 8.1
, the Internet Explorer 11 (IE11)
browser frame process (both “modern UI” and Desktop) runs 64-bit. However, for compatibility with plug-ins, IE11 on the desktop runs 32-bit
tab processes by default.
Enhanced Protected Mode
(EPM) adds additional security to Protected Mode and includes AppContainer and 64-bit tab processes. Like the Windows UI (Metro) Internet Explorer, AppContainer is now on by default on the desktop Internet Explorer. This prevents pages from reading or writing to the rest of the operating system. You can also use 64-bit tabs on the desktop IE (on 64-bit Windows). Running 64-bit tabs increases security on the desktop IE because 64-bit processes offer better protection against attacks that try to damage memory safety.
