Microsoft is once again making changes to how major Windows 10 updates are installed in the OS. The company is making significant changes to the system in order to give users less downtime, letting them work while a big update is being prepared for installation.
Back in April of last year, the offline time for installing a major update was 82 minutes. With the Fall Creators Update in October, Microsoft cut that down to only 51 minutes. And with the upcoming Windows 10 update, Microsoft is introducing further cuts to the offline installation process by bringing down the offline time for major updates to only 30 minutes.
Microsoft was able to cut down the offline time by 21 minutes by making two significant changes to the system: preparation of user content for migration and the process of storing the OS into a temporary directory are now being handled in the “online” process instead of the offline process. So the update system is technically still the same, but two of the processes are now being handled during the online phase to give users less downtime.
