Doing a 'repair' on VS2010 might get the SDK back for you; I'm not
sure.  I believe this link should be what's needed to fix the SDK
after installing VS2010SP1:

If I'm not mistaken, Visual Studio uses the SDK for all of its
building and will install its preferred SDK as a dependency.  It can
use other SDKs as well, though.

Extension building in general is still a mess on Windows, I hope the
links above are enough to get you going again!
