Microsoft released a big crop of updates yesterday for Windows and Microsoft Office programs – there are ten patches on the official list but my computer shows fifteen items ready to be installed this morning. Yesterday Microsoft was having some trouble with the Automatic Updates system but that appears to be resolved now.
You can install the patches manually if you visit the Microsoft Update site, or they should be installed automatically in the next couple of nights. Keep an eye on the lower right corner of the screen, just in case; if you see the gold shield icon by the clock, click on it and the updates will be installed in the background. Your computer will probably have to be restarted after the patches are installed.
