Regular Windows users would probably understand the frustration that stems from having Windows automatically update when you're in the middle of something important. While Microsoft's intentions are good with regards to automatic updates, its execution leaves much to be desired. So it comes as a pleasant surprise that the upcoming Creators Update will allow Windows users a way to stop automatic updates from happening.
First spotted by Winaero, Microsoft appears to have implemented a 'Pause Update' option in its advanced options menu. By enabling this option, Windows will temporarily pause updates from being installed for up to 35 days. While this will stop a large majority of updates from being installed, Windows Defender definition updates will still be installed regardless. What happens after the 35 days are up isn't mentioned, but we're going to assume that Windows 10 would proceed to install said updates after prompting the user to do so.
Currently, the feature is only available in Windows 10 build 14997, a Windows 10 build that was leaked online and was not intended for public use. While the build will eventually be available for members of the Windows Insider program, the feature will not be available until after the New Year. As such, the feature is liable to changes before it goes live.
