Hey testers! In tonight's deploy we're making a few tweaks to how LoL interfaces with operating systems in order to thoroughly vet our compatibility with a few older OS versions. This may result in...oddness...at any or all levels of the LoL experience, from clicking "LeagueofLegends.exe" to any component of the in-game experience to even the game crash process. Please continue to report bugs as normal, even (especially?) if they're really odd. ([Bug reporting guide!](http://community.pbe.leagueoflegends.com/en/c/bugs/CF5EEDC8FF5AC1A896F517E2C7AE4650C472807F))
Because of the potential impact, I also want to take the time to remind everyone that sometimes the PBE explodes, and that's okay. One of (if not THE) biggest purposes of the PBE is to body block complex changes like this from nuking the live servers come patch day.
