Even with a perfect theme, issues happen. Here are fixes for the most common problems with AIO for Windows by niivu.
Problem: "The taskbar is black and unresponsive after applying the theme." Solution: You likely used a Windows 10 theme on Windows 11, or vice versa. Boot into Safe Mode (Shift + Restart), apply the default Windows theme, uninstall the theme patcher, and download the correct AIO version.
Problem: "The file explorer address bar is white on a dark background, making text unreadable."
Solution: This is a Windows bug with third-party themes. Open the AIO folder and look for a file named address bar fix.reg. Merge it into your registry and restart explorer.exe.
Problem: "The start menu is blank or has weird tiles." Solution: You need StartAllBack (paid) or Open-Shell (free). Download the version recommended in niivu’s AIO readme file. Do not rely on the native Windows 11 Start menu for custom themes.
