Program Files C:\Program Files

Default install folder for 64-bit desktop applications. Localized as "Programmes" in the French File Explorer.

What it’s for

C:\Program Files receives desktop (win32) applications by default, 64-bit ones on 64-bit Windows. The %ProgramFiles% variable points to it. Applications should get the path from SHGetKnownFolderPath instead of hard-coding it. The French File Explorer displays it as “Programmes”.

What it contains

One subfolder per installed application (Microsoft Office, browsers, vendor tools) and the shared components (Common Files).
Built-in Windows components, for example Windows Defender or Windows NT.
WindowsApps, hidden and protected, which hosts Microsoft Store apps.
Program Files (x86) only exists on 64-bit Windows. It receives 32-bit software, and some 64-bit software installs there too, depending on the vendor.

Risks and best practices

Writing here requires administrator rights, so an application that stores user data here is poorly designed.
Uninstall an application rather than deleting its folder by hand, so the Registry and services are cleaned up as well.
Do not move the folder: registered paths (services, shortcuts, scheduled tasks) would stop working.
To audit installed software, cross-check its contents with the list of registered programs.

Useful commands
