Go to Start, then All Programs -----> Accessories -----> Command Prompt -----> and finally click Run as administrator. Continue if you receive a notification (User Account Control notifications can be disabled).
Type or paste the following command at the prompt:
net stop wuauserv
ren %systemroot%\SoftwareDistribution SoftwareDistributionold
net start wuauserv
If that doesn't get it done, then follow the steps below to re-register the files responsible for Windows Updates.
