Installer Adjustment App

Overview

Installer Adjustment App is a tool that checks and adjusts files and folders created in the C:\Windows\Installer folder by installers created using Windows Installer technology.

In the initial version of this app, you only need to check the contents of the folder.

Ultimately, we want to be able to delete unused files. This feature allows you to delete unnecessary installer files and increase the free space when storage space is low.

Design policy

Just checking the installer file will not break your system. However, when changing the PC state, such as when adjusting the installer file, in the worst case, the system may be destroyed (apps cannot be started, apps cannot be uninstalled, etc.). Therefore, it shall be designed according to the following policy.

  • Get user permission when changing PC state
    When this application changes the state of the PC, such as deleting unnecessary files or uninstalling unnecessary applications, always operate with the permission of the user. This guarantees that the state of the PC will not be changed just by starting the application.
  • Judgment conditions for unnecessary files are approached in a safe direction
    By setting the judgment conditions in a safe direction, it is possible to prevent the system from breaking when changing the PC status.
  • When changing the state of the PC, try to restore as much as possible
    In the case of file deletion, etc., it is possible to save it once to another location so that it can be restored

Safety is our top priority. Please report us if you find any problems related to vulnerability or safety caused by the design / implementation of this application.
