While installing a software in say d drive what all files get saved in c drive and why?

Even when you install some programs in other drive, say D, it saves the startup links and some dll's in your OS drive (Normally C:\Program files and / or in windows sub directories) for the application to run / start / show up in the menu (Program Menu) / desktop shortcuts etc.

Err... depends on the software your installing. And the options you choose in the installation process,





Some softwares require that you install them in the same drive as windows. Most can be installed in any drive. But some save their history files in C:, eg. Microsoft reader saves its History in My documents.
