The User Interface Global Hook DLLs tab allows you to detect and specify global hook DLLs that may not be wanted in the Performance Validator user interface process

About global hook DLLS
See the similar topic on stub global hooks to read about global hook DLLs
The default behaviour is not to allow the global hooks to load, but you can change this if necessary
•Allow all global hooks to load 
 allows all global hook DLLs to load into Performance Validator 
•Do not allow any global hooks to load 
 prevent any global hook DLLs from loading (the default)
 
•Use the list of dlls shown 
 provide per-DLL control over which DLLs load or don't load via the User Interface Global Hook DLLs list
Any global hook DLLs not listed will result in the user being asked for permission to load a DLL via the Global Hook Warning Dialog below
•Add DLL... 
 browse and select one or more DLLs 
 Open 
 adds the chosen DLLs to the Global Hook DLLs list 
Having added a DLL to the list, you can change whether the DLL is allowed to load or not, by double clicking in the second column and changing the value: Load or Don't load
•Remove 
 removes any selected DLL from the list
•Remove All 
 removes all DLLs from the list
Performance Validator can detect any DLLs in its own process that are not ones it uses itself. Such DLLs are likely to be global hook DLLs:
•Auto Detect 
 automatically detect DLLs which may be global hook DLLs, adding them to the Global Hook DLLs list  
When the global hook loading rule above is set to Use the list of dlls shown, the Allow load column controls whether the hook DLL is loaded.
When a global hook is loaded that is not on the list of known global hooks, the user is presented with a warning dialog like that shown below.
The user can then accept or block the global hook from loading. The dialog lists a couple of known problematic DLLs.

•Help

•Yes

Your response is automatically recorded in the Global Hook DLLs list, so that you won't be asked again.
