ELKA Power Throttle Control

A focused Windows desktop application for managing per-application power throttling with Windows' built-in powercfg commands.

Download

Download the current Windows installer or portable ZIP from the Releases page.

The installer is self-contained for 64-bit Windows; users do not need to install .NET separately.

Features

• Discovers installed applications from machine-wide and per-user registry entries, App Paths, and Start Menu shortcuts.
• Select one or many executable-backed applications.
• Disable or enable power throttling through a visible elevated Command Prompt.
• Open Windows' authoritative powercfg /powerthrottling list output.
• Remembers the displayed application state between runs.
• A general Network workspace searches all discovered applications and filters them by name or executable path.
• Opens TCP, UDP, or both for single ports, comma-separated port lists, and ranges such as 80,443,5000-5010.
• Configures inbound, outbound, or both directions on selectable Private, Domain, and Public profiles.
• A separate VBAN workspace detects running and installed VoiceMeeter, Macro Buttons, VBAN, Matrix, and Matrix Coconut executables, including x86 and x64 editions.
• Offers confirmed advanced full-traffic options, targeted ELKA-rule removal, and elevated rule lists.
• Light, dark, and Windows-system themes.
• The main app runs normally; elevation is requested only for powercfg and firewall actions.

Commands used

powercfg /powerthrottling disable /path "<full executable path>"
powercfg /powerthrottling enable /path "<full executable path>"
powercfg /powerthrottling list

Firewall commands

The general Network workspace creates deterministic, removable program rules for the selected protocol, direction, ports, and profiles. For example:

netsh advfirewall firewall add rule name="ELKA Network - <app> - TCP - In" dir=in action=allow program="<full executable path>" protocol=TCP localport=80,443,5000-5010 profile=private enable=yes
netsh advfirewall firewall add rule name="ELKA Network - <app> - TCP - Out" dir=out action=allow program="<full executable path>" protocol=TCP remoteport=80,443,5000-5010 profile=private enable=yes

The dedicated VBAN workspace retains its focused defaults. VBAN uses UDP port 6980 by default according to the official VoiceMeeter documentation.
