Problematic KB971033 update for Windows7

I recommend that you strongly consider rejecting the manual installation of the Windows Activation Technologies update KB971033, and do not permit Windows Update to install it (this will require that you not have your PC configured in update automatic installation mode, which has other ramifications -- so you may wish to consult a knowledgeable associate if you're not familiar with Windows Update configuration issues).

And if at some point in the future you find that the update has been installed and your PC is still running normally, remove the update as soon as possible.
