Normally there are no random notepads on my desk top.
Ever since the minecraft launcher updated these random notepads documents have been poping on my desktop named "nativelog"

What this notepad contains:
Set run directory to C:\Program Files (x86)\Minecraft
Native Launcher Version: 284

Check to see if we can run the launcher

Started application ./runtime/jre-x64/1.8.0_25/bin/java.exe -cp "C:/Program Files (x86)/Minecraft/game/launcher.jar" net.minecraft.launcher.Main --nativeLauncherVersion 284
Application still running, assuming all's fine.

Which i assume this shouldnt be normal, but it doesnt affect my game. On the Launcher this happens:

This is a modded version (too many items) which did not say this before the launcher update. Sadly every game version that is selected will spit out this message. The problem is what is wrong with the launcher? Running with admin doesn't change a thing.
