Never much liked IE 11 myself.
Why don`t you give google chrome a try, download and install it on your system then set chrome as your default browser in windows OS.
Chrome is faster, and has better control options.
And will likely not freeze when loading web pages ect.
I use it on a windows 7 64 bit os and find it runs much smoother and faster than IE 11 Crypto123.
Maybe you should give it a try.
