Uninstall Software (Machine-Wide)
| 0 Votes |
Description
This task uninstalls a Windows application based on a partial application name provided by the administrator at action time. The task searches for the specified application and executes its registered uninstall command.
Important: This task applies only to applications that are installed system-wide (machine-level installations), typically registered under Programs and Features and installed in C:\Program Files or C:\Program Files (x86).
Applications that were installed per user (user-context installations) are not covered by this task. Such applications are usually installed under %LOCALAPPDATA% or %APPDATA% and register their uninstall information under the user’s registry hive. These applications require a different uninstall approach.
