Google has never published an install count for its free PC operating system. ChromeOS Flex adoption has to be read from proxies instead: StatCounter’s Chrome OS pageview share, the Windows 10 base past its end of support, Google’s certified hardware list and the stock history of a $3 USB kit.
This brief covers each one with September 2026 web data and Google’s list as updated September 2, 2026, plus the Aluminium OS timeline around Flex.
ChromeOS Flex Adoption Statistics
How Many Devices Run ChromeOS Flex in 2026?
Google has not released an install, download or active-device count for ChromeOS Flex. The Flex help pages reviewed for this brief cover hardware and updates, with no usage totals.
StatCounter is the nearest public proxy, but its single “Chrome OS” line covers every Chromebook as well as Flex PCs. That figure measures sampled web pageviews in a month, not devices or people.
Chrome OS Desktop Pageview Share by Region, September 2026
The United States recorded the highest Chrome OS reading of the four regions below; our country-by-country Chromebook share page covers individual markets.

Demand Signals for ChromeOS Flex: Back Market’s $3 USB Kit
Google and Back Market launched the ChromeOS Flex USB Kit on April 2, 2026, at around $3 or €3. Google describes the program as a pilot and the drive as reusable.
Chrome Unboxed reported on April 4, 2026 that the kit had sold out. The outlet reported a restock on June 16, 2026.
Google’s launch post lists no unit volume. The sellout reports are a qualitative demand signal, not a count of installs.
Each drive is waste-compensated: Closing the Loop collects and recycles an equal weight of e-waste per USB drive, Google says. The kit is optional, and ChromeOS Flex stays a free download.

Windows 10 at 27.83% of Windows Pageviews: The ChromeOS Flex Adoption Pool
Win11 accounted for 71.44% of Windows desktop pageviews worldwide in September 2026, and Win10 for 27.83%. Win7 held 0.55%, with Win8.1, WinXP and Win8 each below 0.1%.

Google’s launch post ties the Back Market kit to Windows 10’s end of support in October 2025. Buying new hardware is another route off Windows 10, and our Chromebook vs Windows laptop sales report tracks shipments on both sides.
PIRG put the number of affected computers at up to 400 million in 2025, noting that estimates vary. The group also estimated 1.6 billion pounds of e-waste from the change.
PIRG ties its estimate to 2022 hardware research that found 43% of Windows 10 computers could not move to Windows 11.

When Does Windows 10 Security Coverage End?
Consumer Extended Security Updates now run to October 12, 2027, and enrolled PCs carry over to that date with no action, according to Microsoft. Help Net Security reported the one-year extension on June 26, 2026.
| Program | Enrollment cost | Coverage | Device terms |
|---|---|---|---|
| Consumer ESU | Free with PC settings sync, 1,000 Microsoft Rewards points or $30 one-time | To October 12, 2027 | One license covers up to 10 devices |
| Commercial ESU | $61 per device for Year One; price doubles each consecutive year | Up to 3 years after the October 14, 2025 end of support | Minimum purchase of one license |

Commercial Year One started in November 2025, and coverage is cumulative, so a business joining in Year Two pays for Year One too. Our enterprise desktop OS deployment statistics track fleet-level Windows splits.
ChromeOS Flex carries no license fee for the OS. Organizations that manage Flex devices in the Google Admin console need an Enterprise Upgrade or Education Upgrade for each device, per Google.

Certified Hardware Behind ChromeOS Flex Adoption: Dell and HP by End-of-Support Year
Google’s certified models list, last updated September 2, 2026, has 61 manufacturer sections. Support for each model ends on December 31 of the year shown.
Dell holds 149 rows and HP 182, for 331 combined, based on a row count of the two sections.
| End-of-support year | Dell rows | HP rows |
|---|---|---|
| 2025 (decertified) | 11 | 13 |
| 2026 | 15 | 17 |
| 2027 | 25 | 34 |
| 2028 | 63 | 60 |
| 2029 | 4 | 8 |
| 2030 | 21 | 37 |
| 2031 | 0 | 1 |
| 2032 | 9 | 11 |
| 2033 | 1 | 1 |
| Total | 149 | 182 |
Source: Google, ChromeOS Flex certified models list, updated September 2, 2026 (rows counted for this brief)
The 2028 group is the largest for both vendors, with 63 Dell rows and 60 HP rows.
Another 32 models, 15 Dell and 17 HP, lose certification on December 31, 2026. Google says models past their date are no longer eligible for its support or included in ongoing Flex testing.
HP lists 50 rows certified to 2030 or later, against 31 for Dell. The latest year on either list is 2033, held by the Dell Latitude 5350 and the HP EliteBook 660 G11.
Dell’s count includes the Latitude 7490, listed as “minor issues expected” rather than certified.

Is ChromeOS Flex the Same as a Chromebook?
No. Google documents several differences between Flex PCs and ChromeOS on Chromebooks.
| Feature | ChromeOS Flex |
|---|---|
| Google security chip | Not included |
| ChromeOS verified boot | Not available |
| UEFI Secure Boot | Optional, via a Microsoft-approved bootloader |
| Android apps and Google Play | Not supported |
| ARM processors | Not supported |
| Linux development environment | Varies by model |
| Rollback | Not supported |
Source: Google, Differences between ChromeOS Flex and ChromeOS, checked October 2026
Without the Google security chip, boot checks on a Flex PC rely on its own UEFI firmware; our guide to verifying Secure Boot on Linux covers that setting.
Flex follows the ChromeOS release cycle, with a full OS update about every 4 weeks and minor updates every 2 to 3 weeks. The long-term support channel takes feature updates about every 6 months.

ChromeOS Flex Adoption Outlook: Aluminium OS, Googlebook and the 2033 Floor
Google court filings in its search antitrust case, reported by The Verge in early February 2026, set out the Aluminium OS path: commercial trusted testers in late 2026 and a full release in 2028.
The same filings say Google must maintain existing ChromeOS at least through 2033 to meet its 10-year support commitment.

Google announced Googlebook laptops on May 12, 2026, naming Acer, ASUS, Dell, HP and Lenovo as first partners for fall 2026. Five models were unveiled in September 2026, with sales set to begin in October.

Google’s Flex page still states that Flex follows the ChromeOS release cycle. The 2033 floor in the filings matches the latest end-of-support year on the Dell and HP Flex lists.
