when uninstalling an app on Windows, why do some files get left over?

398 views

I’ve mainly used OSX/MacOS tho right out my life, but have used Windows for work. From my understanding, installing an app on Windows scatters files throughout the OS and makes it sometimes difficult to fully uninstall an app. Often times there are files that are leftover.

In macOS it’s super easy because with a lot of apps, the files are bundled within the app itself making it easier to remove.

Short answer, lazy developers. A well written uninstaller will do something like drop a script/scheduled task to be run on next restart to delete the directory structure for the program. Many can’t do it as part of the actual uninstall process because some of the resources are still protected and will continue to be until the next reboot.
