webkit2webprocess.exe continuously crashes

This is on Windows. I can't find a place to talk about Windows Safari thought, so I'm posting this under "Mac OS & System Software > Safari"

webkit2webprocess.exe continuously crashes, and when it does I'm logged out of mail and all of my accounts in my Safari tabs.

I tried moving the executable to disable it, but Safari downloads it by itself and starts it up again next time I run. I see many people with this problem on the internet, but I've read no solution. Safari seems pretty unusable on Windows 8 for me because of this. This machine is relatively new, I don't have much installed, and I didn't install any plug-ins into Safari.

Safari works fine on my Mac, but unusable on Windows 8 because of this problem.
