Blocking applications in Windows

The current ChainBreaker app has three application-block types: permanent rules, scheduled rules, and blocks activated after a foreground-use limit is reached.

You can configure:
  • a permanent block for a selected executable
  • a schedule for chosen days and hours
  • a daily, weekly, or monthly foreground-use limit

What happens on a launch attempt

The local guard detects a process that matches an active rule, closes it, and records the event. It then shows a 12-second Windows notification with the rule and reason.

  • a permanent block names the responsible rule
  • a schedule includes when the active window ends
  • a limit includes the reached boundary and when the block ends

Choosing the right rule

Use a permanent rule for an app you do not want to open at all, a schedule for protected hours, and a limit when you want a defined amount of foreground use first.

  • select the app by its executable file
  • limit time grows while the app is used in the foreground
  • events stay local and appear in Statistics
