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