Windows 10 installations are slowing down after being available to the public for just a couple of weeks.

Windows 10 is now nearing a 5 percent share of the total operating system market, Tech Radar reports.

Figures obtained by The Register from StatCounter show that Windows 10 owned a 4.95-percent share of the total operating system market as of the end of last week. The figures also show that Windows 10 grew its share by 30 percent in the period of Aug. 9 to Aug. 16.

The increase of 30 percent is impressive for Windows 10, but the second week of availability was the most popular for the new operating system. In the second week, Windows 10 went from a 1.36-percent market share to a 3.78-percent market share, an increase of 177 percent.

Windows 7 owners have been the most likely to upgrade to Windows 10, while Windows 8.1 owners have failed to upgrade as quickly. Windows 8 and Windows XP owners have slowly started upgrading their operating systems to Windows 10.

Windows 10 is seeing its adoption rate slow down, but with almost 5 percent of the operating system market in such a short time, Microsoft should still be pretty happy. With the back to school season getting closer, more computers that have Windows 10 pre-installed will be purchased. Another segment of users that could help boost the Windows 10 adoption rate is the corporate users. These enterprise users traditionally take a longer time to upgrade to a brand new operating system because they want to ensure it is bug-free before installing it in their company's computers.

After a much-criticized Windows 8 and Windows 8.1, Microsoft focused on building a clean operating system that would work with multiple devices, like mobile phones and tablets, in addition to computers.

According to CNET, Microsoft "gets it right" with Windows 10. Almost anyone with Windows 7, Windows 8 and Windows 8.1 can upgrade to Windows 10 for free.
