RegisterDefaultPatchBaseline - Sets the default patch baseline

Call RegisterDefaultPatchBaseline to set the default patch baseline.

Usage notes

Only one default patch baseline can be set for each operating system type. Setting a new default baseline will replace the current one (including any predefined system baseline).

Setting the default patch baseline only applies to newly created patch plans. Existing patch plans will retain the default baseline that was in effect at the time of their creation.
