\u003c/br\u003eET-Optimizer uses: built-in windows tools, contains 360+ registry values and 60+ calls to the system shell.\n\nOriginally ET was a batch script file then evolved into a .bat file with vbs and powershell implemented, then was rewritten entirely to powershell, and over the years became a mostly fully-fledged C# application.\n\nThe first version appeared in a simple version for personal use in 2021.\nSo far the project has grown to: 5000+ lines of code, 900+ commits, translated into 13 languages ​​and is being developed further with love ❤️\n\n\u003cp
