I get an error code 0x80072F8F while searching for the updates in the microsoft site.
Any idea?

Bye.

This error may occur if the date and time on your computer varies too much from the valid date and time of the SSL certificates that are used by the Windows Update Web site. This causes the scan process to fail. Make sure that you verify that the time and date are accurate on your computer.

Check your date and time settings
