64 bit windows missing important service patch - 3.57 on Windows 8

I receive this error every time I start Unity 3.5.7 on Windows 8:

Your 64 bit Windows installation is missing an important service pack patch. Please apply http://support.microsoft.com/kb/976038 to ensure stability.

Unfortunately the hotfixes are only for Vista and Windows 7/2008… There appears no hotfix for Windows 8?

hogwash its not a false positive because i get it too and when i hold shift to resize box collision if i hod for too long a bunch of error signs pops up and my unity closes down .

It’s a false positive. Just ignore the warning now - win8 does not need the hot fix, and a future version of Unity will avoid displaying this message.
