Abstract:
|
|
|
|
This DLL hooks shell32!SHGetFolderLocation, shell32!SHGetSpecialFolderLocation, and
|
|
shell32!SHGetFolderPathA. Any application that is looking for a per-user CSIDL will
|
|
be returned the corosponding all-users location instead.
|
|
|
|
This shim is designed to fool install apps that call shell32.dll api's to obtain
|
|
shell folder locations.
|
|
|
|
History:
|
|
|
|
08/07/2000 reinerf Created
|
|
05/11/2001 markder Modified Removed Desktop redirection as it makes the shim
|
|
too invasive.
