Did you even try to google it first?
For so many questions I answer, all I do is run a Google query and tell people what other people have figured out for me and you.
The 0xc000007b error is not an unknown one on Windows 8 and it seems comes from some DirectX issue it seems and since SFML's DLLs depend in some way on the DXInput, it can cause a bit of trouble.
Did you install DirectX after upgrading? Windows 8 comes with DX support by default, so an manual install of DirectX should not be necessary.

this:
Delete this files from "C:\Windows\System32" "xinput1_1.dll", "xinput1_2.dll", "xinput1_3.dll"... all xinput1_*.dll and run "dxwebsetup.exe" again - thats all! I had the same problem and nothing helped, and now everything works as expected, and the error is gone!
Before you do that, I recommend you update your system (maybe move to Win 8.1), make sure that the VC redist are installed (if your application is built with Visual Studio) and restart your PC.
