Managed-fleet scans and web pageviews give two different readings for Windows 10. Lansweeper found it on 16.9% of scanned Windows clients in July 2026, while StatCounter logged 30.14% of desktop Windows pageviews in August 2026. These enterprise desktop OS deployment statistics cover fleet version mix, Windows servicing dates, ESU pricing, Q2 2026 PC shipments, patch timing and developer platforms, with what each figure measures.
Enterprise Desktop OS Deployment Statistics
Which OS Versions Lead Enterprise Desktop OS Deployment in 2026?
Windows 11 ran on 78.8% of Windows devices in Lansweeper’s HVMND Collective Intelligence data, published 14 July 2026. Windows 10 held 16.9% of Windows clients.
The dataset is a subset of millions of assets across tens of thousands of customer sites. It describes estates already running asset management software, not every PC.
Lansweeper put Windows 10 at roughly half of Windows machines in mid-2025 and about 18.6% by June 2026. It says the decline has since stalled.

Windows 10 Holdouts by Industry
Healthcare and pharmaceuticals carry the highest Windows 10 share at 23.0%, with consumer and retail at 22.7%. Lansweeper places technology, telecom and logistics near 11–12%.
By company size, 21.4% of SMB Windows machines still run Windows 10, against 16.6% at enterprise scale.

Which Windows 10 Machines Cannot Move to Windows 11?
| Segment | Windows 10 devices failing Windows 11 hardware requirements |
|---|---|
| Consumer and retail | 7.8% |
| Transport and logistics | 6.1% |
| Enterprise-scale organisations | 3.8% |
| Manufacturing | 3.0% |
| All Windows 10 devices | 2.8% |
| Healthcare | 1.1% |

Healthcare’s gap is a migration that has not happened, not blocked hardware. Point-of-sale terminals, rugged handhelds and embedded controllers drive the retail and logistics figures.
A Windows 10 device carried an average of 1,903 active CVEs, against 652 on Windows 11. Counting Windows 7, 8.1 and XP too, 18.7% of the Windows estate runs an end-of-life OS.

How Much Does Delaying Enterprise Desktop OS Deployment Cost?
Microsoft sells commercial Windows 10 ESU through Volume Licensing at $61 per device for Year One. The price doubles each consecutive year for a maximum of three years, which puts Year Two at $122 and Year Three at $244.
ESUs are cumulative. An organisation that joins in Year Two pays for Year One as well, and Year One started in November 2025.
ESU carries no extra charge for Windows 10 virtual machines in Windows 365, Azure Virtual Desktop and Azure virtual machines. Windows 10 endpoints connecting to Windows 365 Cloud PCs get up to three years of ESU with an active subscription.

Patch Timing After Enterprise Desktop OS Deployment
Vulnerability exploitation was the initial access route in 31% of breaches in Verizon’s 2026 DBIR, up from 20% a year earlier. The edition analysed more than 22,000 confirmed breaches from incidents between 1 November 2024 and 31 October 2025.
Median time to fully remediate a CISA Known Exploited Vulnerability rose to 43 days from 32. Only 26% of those vulnerabilities were fully remediated, down from 38%, in data Tenable contributed to the report.
