Desktop app usage is still anchored by Windows, but the desktop landscape is not uniform. StatCounter Global Stats recorded Windows at 67.7% of worldwide desktop operating system share in January 2026, while OS X, macOS, Linux, Chrome OS, and an unclassified category made up the rest. Regional figures from April 2026 show a wider spread: Windows reached 81.59% in South America but 57.48% in the United Kingdom. For media and streaming products, these differences matter because the operating system can shape distribution, testing, and the experience of watching or managing content.

Worldwide desktop operating-system share
StatCounter Global Stats reported the following worldwide desktop operating system shares for January 2026:
| Operating system or category | Worldwide share |
|---|---|
| Windows | 67.70% |
| Unknown | 15.26% |
| OS X | 7.03% |
| macOS | 4.76% |
| Linux | 4.02% |
| Chrome OS | 1.23% |
Windows was the clear worldwide leader at 67.7%. The 15.26% “Unknown” category was the second-largest recorded category, ahead of OS X at 7.03%. macOS accounted for 4.76%, Linux for 4.02%, and Chrome OS for 1.23%. These are shares of desktop operating-system activity reported by StatCounter Global Stats, not counts of installed applications or a census of every desktop computer.
The naming split between OS X and macOS is also visible in the source figures. StatCounter listed OS X and macOS separately in January 2026, so the values should be retained as reported rather than silently combined. The same distinction appears in the regional figures below. That makes the table useful for describing the dataset’s categories, while preventing an unsupported claim about a single combined Apple share.
For a desktop app serving media and streaming audiences, the worldwide picture supports broad Windows coverage while still leaving meaningful audiences on Apple operating systems, Linux, and Chrome OS. The presence of a sizeable Unknown category is a reminder that platform analytics may not classify every desktop visit in the same way.
United States, United Kingdom, and Canada
StatCounter Global Stats recorded a different platform mix across three English-speaking markets in April 2026:
| Market | Windows | OS X | Unknown | macOS | Chrome OS | Linux |
|---|---|---|---|---|---|---|
| United States | 59.74% | 15.09% | 9.42% | 8.78% | 4.34% | 2.63% |
| United Kingdom | 57.48% | 16.80% | 13.27% | 6.55% | 3.15% | 2.76% |
| Canada | 58.00% | 19.08% | 8.98% | 7.38% | 3.34% | 3.22% |
In the United States, Windows held 59.74% of desktop operating system share. OS X stood at 15.09%, Unknown at 9.42%, macOS at 8.78%, Chrome OS at 4.34%, and Linux at 2.63%. The figures show a more distributed market than the worldwide January result, with Apple-labeled categories together representing a substantial reported presence even though StatCounter separated OS X and macOS.
The United Kingdom had Windows at 57.48%, OS X at 16.8%, Unknown at 13.27%, macOS at 6.55%, Chrome OS at 3.15%, and Linux at 2.76%. Windows was still the largest category, but the reported Unknown share was higher than in the United States and Canada. That difference matters when interpreting regional analytics: a lower visible share for a named platform does not necessarily mean the same proportion has moved to another named operating system.
Canada recorded Windows at 58%, OS X at 19.08%, Unknown at 8.98%, macOS at 7.38%, Chrome OS at 3.34%, and Linux at 3.22%. Among the three markets in this comparison, Canada had the highest reported OS X share and the highest Linux share. Chrome OS was below the United States figure but above the United Kingdom figure.
Taken together, the three markets show Windows between 57.48% and 59.74% in the April 2026 figures. OS X ranged from 15.09% to 19.08%, while the reported macOS category ranged from 6.55% to 8.78%. These ranges are direct comparisons of the supplied market observations; they do not describe a time trend.
Europe and North America
At the regional level, StatCounter Global Stats reported Windows at 65.68% of desktop operating system share in Europe in April 2026. Europe’s other reported categories were Unknown at 13.51%, OS X at 11.29%, macOS at 4.69%, Linux at 3.31%, and Chrome OS at 1.51%.
North America had Windows at 59.86% in the same month. Its reported shares were OS X at 15.37%, Unknown at 9.84%, macOS at 8.31%, Chrome OS at 3.99%, and Linux at 2.65%.
| Region | Windows | OS X | macOS | Chrome OS | Linux |
|---|---|---|---|---|---|
| Europe | 65.68% | 11.29% | 4.69% | 1.51% | 3.31% |
| North America | 59.86% | 15.37% | 8.31% | 3.99% | 2.65% |
The regional contrast is practical for desktop app planning. Windows had a higher reported share in Europe than in North America, while North America had higher reported shares for OS X, macOS, and Chrome OS. Linux was higher in Europe at 3.31% compared with 2.65% in North America. These measurements come from April 2026 and should be treated as regional snapshots, not forecasts.
For streaming and media software, the figures point to different testing priorities by region. A Windows-first release can address the largest named category in both regions, but North American distribution should account for a comparatively larger Apple and Chrome OS presence. European testing should keep Linux coverage visible because its reported share exceeded North America’s in this comparison.
Asia and South America
Asia’s April 2026 desktop operating system figures were Windows at 63.58%, Unknown at 27.09%, OS X at 3.57%, Linux at 3.12%, macOS at 2.26%, and Chrome OS at 0.38%, according to StatCounter Global Stats. The Unknown category was especially large in this regional snapshot, so the named operating-system percentages do not capture the whole classification picture.
South America showed a stronger Windows concentration. Windows held 81.59% of desktop operating system share, followed by Unknown at 11.3%, Linux at 2.6%, macOS at 2.16%, OS X at 2.07%, and Chrome OS at 0.29%.
| Region | Windows | Unknown | OS X | macOS | Linux | Chrome OS |
|---|---|---|---|---|---|---|
| Asia | 63.58% | 27.09% | 3.57% | 2.26% | 3.12% | 0.38% |
| South America | 81.59% | 11.30% | 2.07% | 2.16% | 2.60% | 0.29% |
The difference between 63.58% Windows share in Asia and 81.59% in South America is one of the largest regional contrasts in the reported April figures. Chrome OS was below 0.4% in both regions, while Linux was 3.12% in Asia and 2.6% in South America. Apple-labeled categories were also much larger in Asia than in South America when the two reported labels are viewed separately.
These results can guide localization and support choices, but they do not provide download totals, active-user counts, or revenue by country. They describe operating-system share, with the measurement period and geography specified by StatCounter Global Stats.
PC market and Windows 11 momentum
The desktop app opportunity also sits within a broader PC market. Gartner reported that worldwide PC shipments reached 245.3 million units in 2024, up 1.3% from 2023. This is a shipment measure for the worldwide PC market, not a count of desktop app users or a measure of operating-system share. It nevertheless indicates that the device category remained large while app publishers were planning for current and next-generation desktop environments.
Microsoft said Windows 11 active devices increased 50% year over year in fiscal Q4 2024. The figure is a Microsoft-reported change in active devices and is not directly interchangeable with the StatCounter operating-system percentages. It does show strong movement within the Windows ecosystem during that reporting period, which can affect decisions about compatibility, feature support, and minimum requirements for new desktop releases.
For media and streaming apps, Windows 11 momentum can support investment in a current Windows experience, but the worldwide and regional StatCounter figures still argue for broad desktop coverage. A Windows 11 increase does not establish that every Windows device uses Windows 11, nor does it quantify users of a particular streaming application.
Apple reported that its active installed base of devices reached a new all-time high across all products and all geographic segments in fiscal Q4 2024. Apple did not quantify that statement in the supplied result, so it should be read as a company-reported milestone rather than converted into a percentage or device total. Alongside the StatCounter observations for OS X and macOS, it supports keeping Apple desktop compatibility in scope without claiming a specific installed-base size.
Desktop apps in a mobile-first commerce environment
Desktop operating-system share is only one part of digital behavior. Adobe reported that mobile revenue share surpassed desktop share for the first time at 51% during the 2023 holiday season, according to the Adobe 2024 U.S. ADI report. Adobe also said mobile revenue share peaked at 61% on Christmas Day during that holiday season.
For November–December 2024, Adobe projected mobile revenue share at 52.5%. This is a forecast for that period, not a measured result and not a desktop operating-system statistic. The distinction matters: a commerce share can move toward mobile even while desktop operating systems continue to support substantial media, work, and management activity.
The Adobe figures are specifically about revenue share in the U.S. holiday context, while the StatCounter figures describe desktop operating-system share across worldwide and regional geographies. They answer different questions. A desktop app for media and streaming may still need reliable playback, account management, library tools, and creator workflows on Windows, macOS, Linux, or Chrome OS even when a larger portion of holiday purchasing occurs on phones.
The combined evidence suggests a platform strategy with several layers: prioritize Windows because it led every supplied StatCounter geography; test Apple operating systems carefully because their reported shares were material in the United States, United Kingdom, Canada, Europe, and North America; retain Linux and Chrome OS coverage where their regional shares justify it; and design connected web and mobile experiences for users whose commerce activity takes place away from the desktop. The percentages above describe measured or reported observations for their stated periods, while the Adobe November–December figure remains a projection.
