It may be a Java problem, or perhaps your Antivirus is stopping it. Restart your computer, take off any Security programs you have running, then try to run the updates. DO REMEMBER to start your AV after doing this.
Most probably, they are already installed. You just get the notification... you can remove it by "Do not remind me of these updates" or something like that. It's in Windows Updates. Java has had a lot of problems, especially with Chrome.
