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