Stardock WindowBlinds 11.07

The industry leader for complete Windows skinning. The late 2025 'v11.07' update features optimized HDR support, automatic dark mode switching for thousands of skins, and improved high-DPI scaling. It allows users to make Windows 11 look identical to Windows XP, Windows 7, or custom futuristic interfaces. While it offers unparalleled deep skinning (including scroll bars and taskbars), its proprietary nature and occasional bugs with Windows Insider builds drive minimalists toward SecureUXTheme and Windhawk.
