During my Tests, I found a Problem in AddMonitor, that is related to
caching: (Windows cache all Monitor-Entries and is using this Cache for
all Monitor-Functions, but we do no caching and check the Registry).

I want to avoid caching all Monitor-Entries or protect all
Monitor-Functions with a Mutex.

When a User installs two Printmonitors at the same Time with the same
Name but with a different Driver-DLL and a Task-Switch comes between
RegQueryValueExW and RegSetValueExW, a Race Condition is possible but
A Critical Section is still needed later, when we load and use the
