Microsoft plans to release over a dozen patches and security updates to Windows starting this coming Tuesday, June 13. Make sure you have Automatic Updates turned on!
To check, open Control Panel, and then open Security Center. The section 'Automatic Updates' should have a green indicator light that says it's ON. If it doesn't, click the link at the bottom of the page called 'Automatic Updates, under the title 'Manage security settings for:'. In the dialog box, select Automatic (recommended), and then click OK.
Microsoft's patches will automatically make their way to your computer.
