Well, if there was any doubt that Microsoft would be pushing out updates quickly, you can put it to bed as the company has released yet another update. Cumulative update 3, which is now live via Windows Update, is rolling out to users around the world. This is the third update in less than two weeks for the OS and while the support page is not live, the last update was primarily patching security vulnerabilities. The supporting documentation for the update can be found here, KB3081438, but it provides no further information about what the update contains; "This update includes improvements to enhance the functionality of Windows 10".
