Windows 10’s 20H1 update will have a “Cloud Download” that downloads the latest Windows files from Microsoft and uses it to reinstall Windows. Now, Microsoft’s Aaron Lower has explained exactly how Cloud Download will work.
In a blog post published on Microsoft’s Windows Insider blog, Lower goes over the history of Windows 10’s built-in reset options, including recovery partitions. He explains how Windows 10’s built-in Reset feature works:
The next major improvement came with Windows 10 and “imageless” recovery. This is done by constructing a new copy of Windows from the existing installation. Because this approach doesn’t use a recovery image it saves storage space on the disk and preserves the latest security updates. The trade-off of this approach is it can take more than 45 minutes and cannot always repair Windows if the installation is in a really bad state or is too corrupted. That is where this latest cloud download option in Reset this PC can help.
