How do I know which process carries out the task on the context menu

When I right-click on a PNG file, I get a context menu that includes Rotate Clockwise and Rotate Counter Clockwise. Both work great.

Very easy: download, unzip and run ShellExView. the program displays the details of shell extensions installed on your computer, and allows you to easily disable and enable each shell extension.

I am trying to figure out what actual
EXE or DLL carries out the actual work
of rotating images. Because, I don't
think Windows XP includes these out of
the box.

The extension is called Shell Image Verbs (Windows Picture and Fax Viewer) and the DLL 'responsible for rotation' would be C:\WINDOWS\system32\shimgvw.dll

You won't find the extension in the registry unless you can identify the CLID. ShellExView does that as well, even better: highlight the entry and hit F2; this will open the registry and jump right to the key you're looking for.

ShellExView is freeware and portable (doesn't require installation)."
