This plugin will replace WIN32.HLP with online help from the MSDN website.
To install: 1) Copy OllyMSDN.dll to OllyDbg's or ImmDbg's plugin directory. 2) Start the debugger. 3) If you haven't done so already, go to Help -> Select API help file and select WIN32.HLP as usual. It doesn't need to be the real file, just one named like that.
To use: *) When you click on Help -> Open API help file, the MSDN online website will be opened instead. *) To get help on individual API calls, right-click on the CALL instruction in the CPU pane and click on "Help on symbolic name".
