Today an update was offered: System Hardware Update - 2014-03-11 Download size: 205 KB You may need to restart your computer for this update to take effect. Update type: Important These updates are released by PC manufacturers to help improve the stability and performance of PC hardware. Help and Support: Microsoft Support I tried the link, but "Microsoft Support" isn't particularly supportive, telling nothing specific about this update, at least that I could find. Earlier in the month I received and I installed a System Firmware Update, which was also dated "2014-03-11". As I recall, the size of that blob was about the same as the one being offered today. Anybody know what today's update is about? Is this "late arrival" a mistake, or is it good, bad or ugly? It would be really helpful if MS provided a little more information about what they're doing.
