Earlier this week, Microsoft announced that Windows 10 was installed on over 75 million PCs and tablets four weeks after its launch on July 29. Now, the company has confirmed that 1.5 million of those Windows 10 installs were of the Enterprise SKUs.

The number was revealed to a group of journalists attending an enterprise-based press event in Redmond, Washington today. Unlike the Windows 10 Home and Windows 10 Pro SKUs, which can be downloaded as a free upgrade for Windows 7 and 8.1 PCs for the next year, the Enterprise SKUs are fully paid versions of the OS.

While it's still a small percentage of the entire Windows 10 install base, having 1.5 million Enterprise PCs users in just one month is still a solid update rate, as the vast majority of Microsoft's large Enterprise customers will likely take their time to convert their PCs to the new OS.
