  - Don't do wild things with Windows drive or UNC notation.
  - Wildcard expansion is disabled by default, though it can be turned on at compile time.  This only affects command line arguments to the binary:  the BusyBox shell has full support for wildcards.
  - Handling of users, groups and permissions is totally bogus.  The system only admits to knowing about the current user and always returns the same hardcoded uid, gid and permission values.
- - Windows XP and Windows Server 2003 don't seem to like how busybox-w32 handles environment variables.  The -X shell option (which must be the first argument) might help.
+ - Windows XP and Windows Server 2003 sometimes have trouble with forward slashes in environment variables.  The -X shell option (which must be the first argument) prevents busybox-w32 from changing backslashes to forward slashes.
+ - Currently only 32-bit builds of BusyBox work.  If you want to install 32-bit BusyBox in a system directory on a 64-bit version of Windows you should put it in `C:\Windows\SysWOW64`, not `C:\Windows\System32`.  On 64-bit systems the latter is for 64-bit binaries.
