In the six months since the launch of its Windows 11 operating system, Microsoft has busied itself with upgrading as many of its teams' PCs as it can. Now, the company has shared a glimpse into how the process is going, celebrating the upgrade as “the smoothest we've ever had.”

In a post on the Windows IT Pro Blog (via Windows Central), content and social program manager at Microsoft Lukas Velush says that “over 190,000 employee devices” have undergone a Windows 11 upgrade. This spree of OS installations took place over five weeks, meaning the company was able to upgrade over 5,000 PCs a day.

However, the rollout of the OS hasn’t been entirely without its hurdles. Velush highlights that “a percentage of [employee] devices” did not meet the Windows 11 requirements and will instead continue to run Windows 10 until their next available device refresh. It also remains unclear how many more systems are yet to receive an upgrade, as Microsoft didn’t specify what fraction the 190,000 PCs previously mentioned makes up of the company’s total installation base.
