Windows 11 is consolidating its hold on the Belgian IT market and is by far the dominant operating system. Many users made the switch from Windows 10 last year.

A year ago, we asked our readers what operating system they were using. Windows 11 came out on top, but many were still using Windows 10. Microsoft is doing everything it can, in increasingly less subtle ways, to get users to upgrade to the latest version of Windows, and it still seems to be bearing fruit. A year later, Windows 11 adoption among IT professionals has risen sharply.

Of a sample of 299 respondents, half (51 percent) say they use Windows 11. This is a significant increase compared to last year, when Windows 11 had to make do with forty percent. Windows 11 is by far the most widely used PC operating system among IT professionals. Could the newly announced Copilot Plus PCs further increase the share of Windows 11?

Is the end of Windows 10 approaching?

Windows 11 has almost completely stolen that extra ten percent from Windows 10. Last year, thirty percent of IT professionals used Windows 10, now that percentage has dropped to 21 percent. Meanwhile, the majority of Windows users seem to have gradually made the switch. The impending end of support for Windows 10 in October 2025 may already have something to do with it.

However, Windows 10 will not immediately disappear from the Belgian IT landscape after this date. Older versions of Windows that are no longer supported still run on three percent of PCs. The use of unsupported software poses many security risks, so it is positive that this share is falling from four to three percent.

After all, there is a status quo in everything that is not Windows. As in the previous year, twelve percent of IT professionals prefer macOS. All Linux distributions together make up thirteen percent.
