Microsoft is changing your Windows Update. The company is killing Secure Boot certificates on most PCs after 15 years, pushing out an update with a critical “Red” warning where “ action is needed ." But the entire update process is also changing , with Microsoft confirming user “disruption from Windows Update.”

“The theme is simple,” Windows Insider lead Marcus Ash posted on Friday. “Less disruption from Windows Update," with "more clarity, more control," as Windows moves "toward a single monthly restart by consolidating OS, .NET, and driver updates, and gives you more flexibility to time updates around your schedule."

This includes the headline change to give users control over the timing of updates, and the ability to start/stop/pause. “You’ll always see the standard Restart and Shut down options without having to install a pending update first. You decide when updates happen, not the other way around.”

Microsoft admits that “updates are an important part of keeping your PC secure and running smoothly, but at the wrong time, they can also critically break your flow.” This has been a ling-running sore for millions of Windows PC owners.

Per Windows Latest , “Microsoft admitted that constant Windows updates were nagging users, and it’s an understatement, considering that we almost always used to get three updates a month, while having to reboot every time.”

These changes hit a week ago, “and speaking of restarts, also include separate options to restart and shut down after downloading an update, allowing you to skip installing an update when you just want to shut down or restart your PC.”

You can also now stop PC updates during the OOBE (out of box experience) when setting up a new Windows PC, which can cut an hour or more from the process.

It means you can pretty much “pause updates indefinitely,” by delaying installs up to 35 days at a time. Obviously, don’t do that. While the update and restart process has been cumbersome and painful, the updates are critical. So users are strongly advised not to let new controls open their PCs up to new threats.
