Problem - Patcher is patching, but after a reboot nothing is modified
UXThemePatcher does not patch all files even if my Windows Version is supported. How do I fix it?
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 Fall Creators Update, some Administration Tools or PDF viewer within Edge do not start anymore
Some Tools like device manager, management console or PDF viewer within Edge do not open after patcher is installed. How do I fix it?
Please uninstall version 3.3.0 of UltraUXThemePatcher and reboot the computer. Afterwards you can install latest version of my Patcher, which do solve this issue.

Problem - After uninstalling the monitor remains black after restart
Every time I try to uninstall your application the monitor remains black after the restart. How can I fix this?
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
I want to completely undo the changes done through the application. How do I do it best?
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 - Display errors in the taskbar after update to new Windows Version.
After upgrading to a newer Windows Version, there are display errors when right clicking on the applications in the taskbar. How can I fix this?
Themes of older Windows Versions are not compatible with Windows the latest Version. Therefore, please contact the developer of the theme, I can not help you here!

Problem - SFC.exe finds modified system files
After check with system file checker modified systems files are found. Why is that the case?
UltraUXThemePatcher works that way! It modifies your system files to make 3rd party themes available. If you do not wnat this, you can not use my application, sorry!
