20 * NOTES:
21 *
22 * Some of these policies can be tweaked via the System Policy
23 * Editor which came with the Win95 Migration Guide, although
24 * there doesn't appear to be an updated Win98 version that
25 * would handle the many new policies introduced since then.
26 * You could easily write one with the information in
27 * this file...
28 *
29 * Up to date as of SHELL32 v5.00 (W2K)
