Editorial review: 4 October 2026 UTC. This guide was reviewed against the linked primary sources. Software installation, firmware changes, disk conversion and hands-on compatibility testing were not performed for this review.
If your PC cannot run a supported Windows 11 configuration, choose an operating system around the work it must do. List the apps, printers, scanners, games, VPN and accessibility tools you cannot lose. A desktop that resembles Windows does not establish Windows software compatibility.
First use the PC Health Check diagnosis guide to rule out a disabled TPM or a boot-mode issue. For an already eligible Windows 11 PC, upgrading its supported version may be the relevant route: 24H2 Home and Pro reach the end of updates on 13 October 2026, while Enterprise and Education have a later deadline in Microsoft’s release table.
Four routes, with different trade-offs
| Route | Useful when | Cost and support boundary | Check before choosing |
|---|---|---|---|
| Windows 10 consumer ESU | You temporarily need existing Windows applications or device drivers. | Enrollment conditions vary by region; critical and important security updates for eligible enrolled devices through 12 October 2027. | Edition, 22H2, update status, enrollment and a plan to migrate before coverage ends. |
| Linux Mint 22.3 “Zena” | You can use native Linux applications or web services. | Free distribution; the 22.3 release is supported until April 2029. | 64-bit PC, hardware support and the actual document/workflow replacements you need. |
| Zorin OS 18.1 | You want its desktop choices and a native Linux workflow. | Core and Education are free; Pro is an optional one-time purchase. Updates and security patches until 1 June 2029. | Intel/AMD x86-64 hardware, edition storage needs and app compatibility. |
| ChromeOS Flex | Your workload primarily runs in a browser. | No-charge personal OS route; organization management and support are separate. Google’s certification end date is specific to the exact device model. | Certified model and end date, storage-erasing installation, peripheral and app limitations. |

Windows 10 ESU: time to migrate, not full support
Windows 10 general support ended on 14 October 2025. The consumer ESU program covers eligible Windows 10 22H2 editions and delivers critical and important security updates; it does not add features, non-security improvements or general technical support. Microsoft currently says enrolled coverage continues through 12 October 2027.
Check the regional enrollment screen instead of assuming a single worldwide price or a paid renewal in October 2026. Free enrollment routes and a paid route are described in Microsoft’s consumer information, with regional differences. Read ESU coverage and enrollment options; if the link is missing, use the missing ESU enrollment checklist. Commercial arrangements and LTSC lifecycles are separate.
This is an interim option when changing an app or peripheral would interrupt essential work. Write down a migration date and verify the enrollment status and delivered updates on the actual PC. An antivirus subscription by itself does not replace operating-system security updates.
Linux Mint: choose an edition, then check the workload
The Mint release list offers 22.3 in Cinnamon, MATE and Xfce editions. Its FAQ lists 2 GB RAM, 20 GB disk space and 1024 × 768 display as minimums, recommending 4 GB RAM and 100 GB storage for comfortable use. Those figures are not a promise about a browser with many tabs, a large slicer project or a game.
Download through Linux Mint’s official download page and follow the linked integrity-verification instructions for your chosen ISO. We did not download or verify a Mint ISO in this review. Compare the desktop editions on your own hardware instead of assuming a “light” label guarantees a performance improvement.
Check the 22.3 release notes for hardware and installation issues. Mint permits commercial use; its own software and the bundled components have their respective licenses. Optional drivers and applications can introduce different terms. “Free download” does not make every included or subsequently installed component one uniformly licensed product.
Zorin OS: free Core first, optional Pro for its extras
Zorin’s details page lists 18.1 as current, based on Ubuntu 24.04 LTS, with x86-64 Intel/AMD processor support. The minimum requirements are a 1 GHz dual-core CPU, 2 GB RAM and an 800 × 600 display; storage differs by edition: 15 GB Core, 35 GB Education and 45 GB Pro. ARM-based Surface devices are not currently compatible, and Apple silicon Macs do not run it natively.
Core and Education are free downloads. Pro adds layouts, bundled apps and installation support for a one-time payment; its numeric regional checkout price was not available in the retrieved page, so this comparison does not quote a universal amount. Paying for Pro is not a requirement for Windows App Support. Lite is separately linked by Zorin; check the edition you actually intend to install.
Zorin’s Windows App Support documentation describes a Wine compatibility layer and explicitly notes that not all Windows apps are fully compatible. Prefer a native version or alternative where possible. Test your exact app version, plugins, files and account sign-in; an installer that opens is not proof the full workflow works. Application and driver licenses remain separate from the cost of Zorin.
ChromeOS Flex: certify the exact model
Google’s preparation guide requires an Intel/AMD x86-64 device, 4 GB RAM, 16 GB internal storage and USB boot support. It now warns that Intel/AMD processor or graphics components from 2012 or earlier, and Nvidia components from 2014 or earlier, are not recommended or supported. Flex is therefore not a universal rescue option for the oldest PCs.
Find the exact model in the certified list, including its certification end date and known issues. Similar model names and different hardware variants are not interchangeable. Google does not guarantee performance, functionality or stability on non-certified models. Managed technical support also has its own enrollment conditions.
Read the differences from Chromebook ChromeOS: Flex does not offer a normal Google Play Android-app library; some Android VPN deployments are an exception. Linux development-environment availability varies by model. Flex lacks Chromebook hardware verified boot, and firmware updates remain the manufacturer’s responsibility. Do not equate certification with an indefinite guarantee of all Chromebook features.
Installing Flex erases existing data, applications, settings and the operating system. Google’s installation guide says data can be unrecoverable even if installation fails. Its “Try it first” USB option is for temporary exploration; live boot has storage/performance limits and no automatic updates. Confirm backups before full installation.
A compatibility checklist before erasing Windows
- Applications: open representative documents and verify formatting, macros, fonts, export formats and plugins. Check any Windows-only licensing or activation requirement with its publisher.
- Peripherals: identify exact printer/scanner models and test a real print or scan. For 3D printing, check the slicer’s Linux package requirements and printer connection separately; see Bambu Studio platform limits.
- Daily hardware: in a supported trial session, check Wi-Fi, Bluetooth, audio, webcam, display scaling, sleep/wake and external monitors. USB-session performance is not the final installed-system benchmark.
- Recovery: copy files off the target disk, verify that the copies open, retain recovery keys and needed installer/licensing information, and prepare the manufacturer’s recovery route. No restore test was performed by this review.
- Decision: if a critical workflow fails, keep the current installation while you investigate a supported alternative. Do not buy Pro or erase Windows just because the desktop looks familiar.
For USB-writing choices use Ventoy, Rufus and balenaEtcher compared. Obtain images from the publisher and apply the official-source checklist before writing a USB drive.
