Microsoft, for example, pulled the October 2018 Update for Windows 10 after reports of data loss and other issues emerged. These issues did not affect all users or even the majority, but it was reason enough to pause the update for about six weeks to sort things out.

Michael Fortin, Windows Corporate Vice President, published "Windows monthly security and quality updates overview" on the Windows Experience blog on December 10, 2018 as part of the Windows approach to quality series.

Fortin explains that Microsoft is updating up to 1000 devices per second during peak time, and that the company's infrastructure and systems support a rapid distribution of security updates and other updates to hundreds of millions of devices.

Update quality is critical according to Fortin considering the "important of the security and other fixes" that Microsoft releases each regularly at scale.
