Windows 8.1 - Games Won't Launch

[String]

Hi,

All my games launched fine in Windows 8. Now that I have updated to 8.1, none of my games will launch. I have tried running in compatibility mode for Windows 7 & 8, and I have tried running as administrator.

Please help!

Did you find an answer to this ? I Updated Windows 8 to 8.1 last night and not one game will run any more.

I have upgraded to windows 8.1 too but my games are working without any problems.

Which games exactly are not working for you?

- Have you updated your graphicscard drivers?
- Have you tried to reinstall Steam?
- Have you tried to verify the integrity of the game cache? (Right-click on the game in your Steam library - properties)

What the above poster said. It's probably your firewall or something blocking the games. I had trouble loading some saved games for a bit with win 8 and had to run the game as a new game start and then load my old save. Steam has some files that are needed to start games also that might be getting blocked like steam bootstrapper or whatever it's called.

Windows 8.1 has a lot of complications right now, might be best to revert to 8 for the time being.

I also have experienced and still experiencing so many issues. From STEAM launch problems to games not launching. I've tried all the known things to do. And, sometimes resintalling .NET from programs and features work and sometimes it doesn't. I've also tried a fresh install and redownloading the STEAM games. Yes, I lost over 2 Terrabytes due to this. I'v etried the latest Nvidia R331 drivers. Nothing seems to stop it from coming back. IF I get it to work if I have to shut down or reboot it wll come back upon rebooting. Needless to day, Im 1000 percent convinced STEAM and Windows 8.1 is BORKED. What is being done about it? So far googling everything NOTHING. Generic responsis from STEAM and Microsoft about verifying game cache. You konw the same ole' responses. Hello if you've reinstalled your entire PC and started from scratch for it to come back then obviously Windows 8.1 and STEAM aren't playing nice together. As I said I've gotten it to work temporarily by reinstalling .NET 3.5 but it ALWAYS comes back on reboot. It's broken stay away from Wnidows 8.1 until they find and fix it.
