It was a substantial update, but the Windows 10 Anniversary update was never going to ring the end for patches and fixes on Microsoft's OS. Windows users will do well to update their machines, after Microsoft rolled out a series of tweaks to tidy up security issues (some critical) on the platform.
Build 14393.51 sorts out a number of critical bugs for the Edge browser, some serious enough to let hackers in the know remotely take control of your machine. The ageing internet Explorer 11 gets a spruce up to improve its reliability, while those using a Surface Pen will see a bug relating to its pen-click settings stored after an update fixed. A Bluetooth bug that would make Windows 10 mobile devices hang has been ironed out, while security updates to kernel mode drivers, Microsoft Graphics Component, Edge, Internet Explorer 11 and Windows Authentication methods wrap things up.
Microsoft Office gets its own patch relating to a vulnerability in the preview pane, as does Microsoft PDF, which could be exploited if opened by nefarious PDF links in the Edge browser. Attacks relating to specific fonts opened in Word, Excel and even Skype have also been addressed.
