Use it at your own risk! Because skin packs will change file system (imageres.dll) to change icons so anti virus give warning, please disable temporary if you’re using anti virus. if your theme not changed or its like classic windows you need to install uxtheme patcher from here and after restart select new theme from personalization.
Note: Please unistall old or other version of skin packs before install new one. Best work on 100% scale and layout size, you need to set it from display setting, Also for enable start menu and taskbar skin you need to install startisback from target=”_blank” rel=”noopener”>here.
