After Topaz deinstall, delete everything called “Topaz…” into following locations:
C:\Program Files
C:\Program Files\Common Files\Adobe\Plug-Ins
C:\ProgramData
C:\Users\All Users
%username%\Documents
%username%\AppData\Roaming
%username%\AppData\Local
%username%\AppData\Local\NVIDIA\NvBackend...topaz…
Registry
HKEY_CURRENT_USER\SOFTWARE\Topaz Labs LLC\HKEY_LOCAL_MACHINE\SOFTWARE\Topaz Labs LLC\
But you can use Registry-Cleaner. Since they started “CCleaner” monetizing it’s become awful. I use the Windows app “Wise Registry Cleaner” which is available for free in the Microsoft Store.
