I am using a genuine version of windows 7 professional 64 bit. During the download of two new windows updates, we had a power cut. The computer restarted fine, but now the two updates will appear to successfully install, and then I check for updates again and it says the same two updates are not installed. I have repeated this process about 4 times now. I have tried hiding the updates, and then restoring them, but the same thing happens. It starts by "installing" the updates, even though before the power cut it had yet to fully download them. How can I reset it so that it attempts to download them again, and hopefully install successfully this time?
