Overwrites User.ini on installation, so you'll lose your Single Player keybinds
They have got to be joking! Don't they have any computer programmers that can read their own user.ini file and write the existing settings to the new file?
Dramatically increases Single Player GFWL sign-in time due to added GFWL sign-in bug
This is no typo. Apparently 2K is as frustrated with GFWL as the players are. The "bug" being referred to is due to the GFWL Client being a port of the console system. Apparently console systems don't have a local security policy that users can change like they can in Windows, so GFWL assumes it can do anything in Windows which it can on the console.
When Windows is installed it allows everyone to access the computer from the network...except for the "Guest" account. For security reasons I change this to indicate that nobody can access my computer from the network...this one and only change prevents GFWL from working. From this effect I interpret that GFWL is trying to access my computer using Windows credentials that either it collected while running on my system and transmitted to its server...or a credential that Windows has available as a backdoor...or some method which Microsoft is not telling us about which requires a remote system to logon to my computer. If I allow access to my computer from the network then GFWL works, but so would hacks which impersonate Windows accounts. As long as Steam is available I can maintain a secured system and play games on the same system...even if someone steals my username and password. If GFWL continues to be used by PC games then the door for hackers will continue to be open...bet you didn't know that did you?
