Start > control panel > windows update.
Click on settings.
Select download but let me chose whether to install.
Click on OK.
Click on check for updates.
If there are updates you should be able to see what they are.
If you don't know what some update is about plug the KB number into google.
The late June Windows updates do not install. I keep having to start the computer in Safe Mode and going back to the previous format. I have found how to stop the automatic updates and I hope that this will help for a while, but how do I know what updates I really need?
