Version 3.81.01 adds support for Windows 8. There is no support for Metro apps, just desktop.

The 64-bit version of Windows 8 includes an updated Kernel Patch Protection facility (PatchGuard) which causes Experimental Protection to crash the system. It also includes new protection on the win32k part of the kernel, so Sandboxie can't supervise window-to-window communications. This last thing should affect a long list of of 64-bit security software so we'll have to see how that goes.

Support is limited to build 8400 at this time. I'm aware that newer builds have leaked to torrent sites but I'm not going to download those builds, so please don't ask.
