Microsoft reissues Update KB3097877
The original patch was supposed to fix various network issues but caused more issues than it fixed on Windows 7 computers. See updated patch info here
Microsoft susequently reissued the patch and the current version really does seem to fix the issues the original patch tried to fix.
