Currently I have an installer created using NSIS. Now I want to create an update installer which updates the application to the newer version by copying only the changed files. The target platform is windows.

The question is too broad. It will probably get flagged as invalid. BTW,
- if your installer overwrites all files, it could work as a not-very-clean updater too.
- Ultimately, your installer/updater should check on start, if the program is already installed, and if necessary, uninstall it before installing the new version. I recommend it calls the uninstaller installed by your first installed, and then performs a regular install. You should keep registry records if you want to keep current settings.
