  • It depends on what you are installing and who wrote the installation program. 

    On most of the programs I installed, the default directory was not c:\ but one of the subdirectories on that drive.

    The installation location is usually determined by a registry entry or a program installation option/preference.

    If you want to change the location, create a folder on the drive/location you want to install programs, call it, unimaginatively, Program Files. Open a Run window (Windows Logo key+R), type regedit, press Enter and in the left pane navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion.

    In the right pane, right-click ProgramFilesDir and Modify it to the drive/folder of your choice, e.g. D:\Program Files which will, in future, put all new programs on the D drive.
