About
Professional Windows system cleaning and optimization tool. Clean temporary files, manage startup, find duplicates, apply 30+ performance tweaks for gaming, and monitor system health.
The Ultimate Windows Optimization Toolkit
Clean · Tweak · Monitor · Supercharge
System Sweep is a Windows system cleaning and optimization tool built with WPF and Fluent Design.
It cleans temporary files, manages startup programs, finds duplicates, applies 30+ performance tweaks for gaming, and monitors system health in real time.
Licensing is handled by KeyAuth (https://keyauth.cc). The app authenticates a
license key against the KeyAuth API on every start (online only) and re-checks
the session every 4 minutes. There is no offline mode.
Configuration is read at runtime from a .env file placed next to the exe or
in the project root:
Variable
Description
KEYAUTH_NAME
KeyAuth application name
KEYAUTH_OWNERID
KeyAuth owner id
KEYAUTH_SECRET
KeyAuth application secret (used by Seller API; not sent by the v1.3 client)
KEYAUTH_VERSION
App version as configured in the KeyAuth dashboard
Copy .env.example to .env, fill in the values from your KeyAuth dashboard,
and never commit .env. Users who enter a valid key get full access; the
"Demo Mode" button on the activation screen runs the app with all cleaning and
tweak actions disabled.
