    Problem - Patcher is patching, but after a reboot nothing is modified
    In rare cases after a Windows 10 Update, the patcher is not able to take ownership of the necessary files in c:\windows\system32 (uxtheme.dll, uxinit.dll, themeui.dll). Only solution today: Sign in as Administrator, take ownership to the 3 files and grant full authorization, reboot and afterwards use the patcher again as Administrator. The modification should work now.
    Problem - After patching on Windows 10 and login into, the PC get black screen and reboots
    A 4k monitor or higher uses a special resolution, therefor themes are necessary that support 200% DPI (e.g. here)!
    Problem - After uninstalling the monitor remains black after restart
    Fast Startup/FastBoot is the problem. 1) disable Fast Startup, 2) shut down (do not restart), 3) boot up, 4) uninstall UltraUxThemePatcher! For more information have a look at detailed tutorial. Is this too late, only a repair installation (inplace upgrade) or a complete new installation helps.
    Problem - Completely undo changes
    First, always a standard Windows theme should be set, otherwise it may cause problems when booting (see problem 3). Thereafter, the application should simply be removed through software -> uninstall. All backups will be restored so the original files are back!
    Problem - No file explorer folders will open from the start menu or in certain apps save dialogs look broken
    Please uninstall the patcher and run sfc.exe /scannow from the comand line! After a reboot a reinstall of the patcher should work again
    Problem - Explorer crashes or display errors after update
    Themes of older Windows Versions are not compatible with the latest Windows Version. Therefore, please contact the developer of the theme, I can not help you here!
    Problem - SFC.exe finds modified system files
    UltraUXThemePatcher works that way! It modifies your system files to make 3rd party themes available. If you do not want this, you can not use my application, sorry!
