Many of the Windows users don’t like to install the applications in the windows installation Drive.Usually people keep their Windows Operating System in C drive and the Softwares in D:\Program Files.
But whenever a new application is installed, the default path is C:\Program Files. And you usually change the path manually to D:\Program Files
But you can change the registry and can set your default installation path to your desired path (Eg D:\Program Files”)permanently within few seconds. And whenever a new application is installed, you don’t need to manually select your favorite path.

Follow these steps to change your default installation directory

1) Click on start button. Select Run. Type regedit. Click Ok.

2) Now you can see the registry Editor.

3).In the left panel Navigate to the following key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
4) In the right panel, select ProgramFilesDir.

5) Double click(or right click and select modify) on that and change the value to your desired path(Eg:D:\Program Files). Click OK.

You are done!! I hope this post will save you some time in the future.

Note:The changes will take effect only after rebooting
