🔧 Overview
The Tech-AD Performance Issue Fixer Toolkit is a command-line utility designed to diagnose and resolve common Windows performance issues quickly.
It provides one-click access to important maintenance tools, cleanup utilities, and diagnostic reports — all from a single interface.
This tool is ideal for IT support staff, technicians, and end-users who want to optimize their system’s performance, troubleshoot errors, and maintain stability.
Lite Vs Full Version
The difference is with option number 7. That has option to choose from several third party apps to help troubleshoot and improve performance of Windows system.
In Lite version these apps are downloaded when choose the option. So initial download is lite and only tools that you need are actually downloaded when you choose. Downside is if/when you need third-party tools you need to be connected to the internet. Also, system should have the Background Intelligent Transfer Service (BITS) service enabled in the system (which usually is).
In Full version all the third-party apps are downloaded together with the apps. So all the options can be used without internet. However, it makes the initial download heavier.
