There is the HKEY_CURRENT_USER\Software\Wine registry keys.  I don't
know if it stores the actual WINE version anymore, but it should only
exist if you are running under WINE.

Note that WINE isn't a sandbox.  I believe it is possible for Win32
applications running under WINE to produce interrupts (0x80?) and make
Linux system API calls.
