Spybot - Search & Destroy

By default, Spybot - Search & Destroy tries to load the profiles of other user accounts into memory, but does not affect inactive installations, e.g. when you're running multiple Windows versions on different partitions. To load every registry hive it is able to find, specify this parameter.

An exception to this rule is when you are running Spybot - Search & Destroy from Windows PE, in which case it is assumed you're running it from CD to fix an inactive system, and all hives will be loaded automatically, even without specifying this parameter.

Command Line Edition

The command line edition does understand this parameter as well, for the same functionality, including automated hive loading when running Windows PE.
