Hello, thank you for your work. First I'd like to inform you that "NVIDIA predefined profiles CAN be restored". When you remove a profile, it writes to one of the two files: nvdrsdb0.bin or nvdrsdb1.bin (looks like half of the profiles are linked to the first file and another half - to the second one). Those files can be found in the \ProgramData\NVIDIA Corporation\Drs folder. But those predefined profiles are not stored in those two files and if you remove them - all predefined profiles will be restored. You might try it yourself. Second - there's a reason for me to try and remove all preinstalled nvidia profiles for all applications. The problem is that with your program I can only remove 1 profile at a time and after each time it jumps to the default profile so I need to press "Down" everytime, plus after I confirmed the remove it shows another window saying it's removed which I do not want to see. So please tell me how to remove several profiles at a time or even all of them without pressing all those redundant buttons?
