In addition to the large files and numerous features included in Windows 10 updates, internet speed can significantly affect installation times. And it takes even longer if you have a fragmented or nearly filled hard drive. For instance, the latest Fall Creators update, which made plenty of adjustments to Cortana, Photos, and Edge, can take upwards of four hours to install.

Windows 10 updates take a while to complete because Microsoft is constantly adding larger files and features to them. Fortunately, there are a few things you can do to speed things up. However, the updates can take hours, especially when a major new feature is being released. Keeping up with Windows 10 updates is absolutely critical if you want the latest features and security fixes on your computers.
