This one is the easy but tedious method
if you wanna use imagemagick to make it faster you first hav to download it here and move all your files where you installed the program.
next you want to create a .bat files and write this thing:
for /r %%v in (*.png) do (
magick.exe %%v %%vMask -alpha Off -compose CopyOpacity -composite "%%v"
del %%vMask
)
and open it with the administrator privileges.
