This should probably be a menu and/or toolbar function, rather than a Configuration function, since each call to "Wow64DisableWow64FsRedirection" has to be paired with a "Wow64RevertWow64FsRedirection" to revert it back. Thus, it wouldn't last past the active session (nor would you want it to, given the potential problems with disabling WOW64 Redirection).
XY should probably default to leaving this option off upon startup, and only toggle it on demand.
Hopefully this won't cause more problems than it solves.
