Windows 8 bugs that have persisted through RP

One Windows 8 bug that seems like an easy fix that has persisted from the DP through the RP for me is that Windows 8 fails to recognize a JIS keboard layout when the Japanese IME is enabled. For some reason, when using the Japanese IME it defaults to a US keyboard layout which really sucks because all the symbol marks are moved around and the Japanese specific keys don't do anything. Does anyone else have a pet bug that really needs to be fixed before RTM?
