26-Nov-1991 JohnRo
|
|
Created.
|
|
13-Feb-1992 JohnRo
|
|
Added support for using the real Win32 registry.
|
|
Added support for FAKE_PER_PROCESS_RW_CONFIG handling.
|
|
12-Mar-1992 JohnRo
|
|
Changed to only store UNICODE strings in registry.
|

|
|
Flush the registry after each create/_write.

|
|
REG_SZ now implies a UNICODE string, so we can't use REG_USZ anymore.
