Provides generalized Windows registry querying.

All key names are one string in the format:

"[base key]\[sub-keys]\value"

[base key] can be any of the following:

HKEY_CLASSES_ROOT

HKEY_CURRENT_CONFIG

HKEY_CURRENT_USER

HKEY_LOCAL_MACHINE

HKEY_PERFORMANCE_NLSTEXT
|
|
HKEY_PERFORMANCE_TEXT
|
|
HKEY_USERS

keyExists() should be used to validate a key before reading or writing
|
|
to ensure that a debug assert or false return is for a different error.
