Windows Registry: Loading and Unloading All User Hives

Today my team was discussing the need to search all user registry hives when scanning for malware.

It's not too bad to do this manually if there are a two user profiles on a system, but it gets considerably more tedious on common-use PCs with more user profiles.  And I'm lazy.

The process might also prove handy for other registry-related tasks, where perhaps can't use Group Policy to be lazy.

Queue Load-UserHives.ps1. This quick-and-dirty PowerShell will search the system for available user profiles and load each key.  Later, you can reverse this with the -Unload switch.  Rather than externally tracking what was loaded prior, a simple naming prefix is used for the unload process.
