2 * shpolicy.c - Data for shell/system policies.
3 *
4 * Created 1999 by Ian Schmidt <ischmidt@cfl.rr.com>
5 *
6 * Some of these policies can be tweaked via the System Policy
7 * Editor which came with the Win95 Migration Guide, although
8 * there doesn't appear to be an updated Win98 version that
9 * would handle the many new policies introduced since then.
10 * You could easily write one with the information in
11 * this file...
12 *
13 * Up to date as of SHELL32 v4.72 (Win98, Win95 with MSIE 5)
