The October 14, 2025, end-of-support deadline for Windows 10 is more than a calendar milestone—it’s a hard stop on security patches, technical assistance, and feature updates for one of Microsoft’s most widely used operating systems. While the company urges users to upgrade to Windows 11 or enroll in paid Extended Security Updates (ESU), a growing number of Ukrainians are charting a different course: they’re installing free, open-source Linux distributions to keep aging hardware alive and secure.

Microsoft’s official lifecycle page leaves no ambiguity. After October 14, 2025, Windows 10 Home, Pro, Enterprise, and Education editions will no longer receive any updates. “While you could continue to use a PC running Windows 10, without continued software and security updates, your PC will be at a greater risk for viruses and malware,” the company warns. Its recommended paths are clear: upgrade to Windows 11 if the PC meets minimum requirements, buy a new Windows 11 device, or purchase consumer ESU—a one-year paid extension available through October 2026. For many Ukrainians, however, these options are either technically impossible or financially out of reach.

Windows 11’s hardware demands—Secure Boot, TPM 2.0, UEFI firmware, and a relatively modern processor—lock out a vast fleet of older but perfectly functional laptops and desktops. In Ukraine, where economic constraints often mean stretching the lifespan of every device, the idea of discarding a working PC simply because it cannot run Windows 11 is non-negotiable. That reality has sparked a surge of local advice columns, community repair cafés, and online guides pointing users toward Linux.

The five free alternatives gaining traction in Ukraine

Ukrainian tech outlets, including a widely shared article on 112.ua, have coalesced around a shortlist of user-friendly Linux distributions and one experimental Windows clone. These are the operating systems being recommended as practical, cost-free replacements for Windows 10.

Zorin OS – the familiar face of Linux
Based on the rock-solid foundation of Ubuntu LTS, Zorin OS is engineered to feel instantly comfortable for Windows refugees. Its “Zorin Appearance” tool lets users toggle between desktop layouts that mimic Windows, macOS, or classic GNOME, dramatically flattening the learning curve. The free Core edition comes with preinstalled drivers, multimedia codecs, and easy access to Flatpak and Snap applications. For a fee, the Pro edition adds extra layouts and commercial support. “Zorin OS is the closest thing to Windows without actually being Windows,” one community guide notes. It runs well on mid-range hardware and even offers a Lite variant for older machines.

Linux Mint – the steady, conservative choice
Linux Mint’s Cinnamon desktop environment deliberately echoes the look and feel of Windows 7, complete with a start menu, system tray, and taskbar. Under the hood, it shares Ubuntu’s Long Term Support base, meaning security updates flow for years. Mint ships with a thoughtfully curated set of applications, a driver manager that simplifies proprietary hardware support, and Timeshift for system snapshots. Wine can be layered on to run many Windows programs, though it requires manual setup. For users who value stability over novelty, Mint is a perennial favorite.

Kubuntu – KDE Plasma’s customizable powerhouse
Kubuntu pairs Ubuntu’s reliability with the KDE Plasma desktop, arguably the most configurable interface in the Linux world. Plasma’s widget-based panels can be themed to closely resemble Windows 10 or 11, and its vast library of community add-ons lets power users tweak every pixel. This flexibility comes at a cost: Plasma’s graphical effects can strain older integrated graphics, and the sheer number of settings may overwhelm newcomers. But for tinkerers willing to invest a little time, Kubuntu delivers a modern, feature-rich experience that rivals any commercial OS.

Deepin – macOS-inspired elegance on a budget
Developed in China, Deepin stands out with its Deepin Desktop Environment (DDE), which emphasizes smooth animations, translucent panels, and a curated set of native apps. The visual polish evokes macOS, but the underlying system is Debian-based, giving it access to a massive software repository. Recent releases have drawn attention for their internationalization efforts and a simplified app store. However, all that eye candy demands newer hardware—8GB of RAM is recommended for comfortable use—and some users have raised privacy questions given the project’s origins. Still, for those who prize aesthetics and a seamless out-of-box experience, Deepin is a compelling contender.

ReactOS – the experimental Windows reimplementation
Strictly for testing and legacy scenarios, ReactOS is an open-source project that aims to rebuild the Windows NT architecture from scratch, promising native binary compatibility with Windows applications and drivers. Its interface looks like classic Windows, and the ambition is audacious. But ReactOS remains in alpha status; the developers themselves caution that it is “not recommended for production use.” It can be unstable, incompatible with modern software, and should only be run inside a virtual machine or on disposable test hardware. For running a cherished Windows 95-era utility that refuses to cooperate with Wine, ReactOS might be the answer—as long as you don’t bet your daily workflow on it.

How to migrate safely: a step-by-step guide

Switching from Windows 10 to Linux doesn’t have to be a leap in the dark. Ukrainian community organizers and experienced users emphasize a methodical approach:

  • Inventory your hardware and software. Note down your CPU, RAM, storage, and any peripherals like printers or scanners. List the applications you rely on daily and check whether native Linux versions exist or if Wine/Proton can run them.
  • Test with a live USB. Almost all Linux distributions offer a “try before you install” mode. Create a bootable USB stick, plug it in, and verify that Wi-Fi, sound, display, and keyboard work as expected. This is the single most important step to avoid post-install surprises.
  • Back up everything. Use an external drive and cloud services to copy all important files. Verify that you can restore them before you commit to any change.
  • Choose your migration path. Three common routes are:
  • Full install: Wipe Windows entirely. Fast and clean, but irreversible without backups.
  • Dual-boot: Keep Windows 10 alongside Linux. Useful for fallback, but can complicate bootloader maintenance.
  • Virtual machine: Install Linux inside a VM on Windows, or vice versa. Ideal for gradual transitions and running legacy Windows apps.
  • Set up Windows app compatibility. For software that can’t be replaced, install Wine, Winetricks, or Lutris. VirtualBox or VMware can run a full Windows environment if needed. Linux Mint’s comprehensive community wiki and forums provide step-by-step guidance.
  • Secure the new system. Enable automatic updates, configure the firewall, and consider disk encryption.
  • Seek local help. Across Ukraine, volunteer-led repair cafés and Linux user groups are organizing “End of 10” workshops where people can try out live USBs and receive hands-on installation assistance.

Application compatibility and peripheral realities

Office productivity sees the smoothest transition. LibreOffice and OnlyOffice handle most document, spreadsheet, and presentation tasks, while the web-based Microsoft 365 suite fills gaps for those tied to the ecosystem. Microsoft itself says Microsoft 365 Apps will receive security updates on Windows 10 until October 2028, but they will no longer be supported for that OS after 2025, and performance may degrade.

Specialized industry software remains the toughest hurdle. Many proprietary applications lack Linux ports, and while Wine or a virtual machine can bridge the gap, this adds complexity and resource overhead. For mission-critical tools, maintaining a secondary Windows machine (patched and isolated) or purchasing ESU for a limited period may be necessary.

Gaming has improved dramatically thanks to Valve’s Proton and Steam Play, but anti-cheat systems in some competitive titles still cause problems. Printers and scanners are generally well-supported by modern Linux kernels, though older or obscure models may require manual driver hunting. A live USB test is the ultimate compatibility check.

The security equation

Continuing to use Windows 10 after October 2025 without ESU is a deliberate risk. Unpatched vulnerabilities will accumulate, and any internet-connected machine becomes an increasingly soft target. Microsoft’s ESU program for consumers costs $30 for the first year and requires a Microsoft account—a caveat that privacy-conscious users may find grating. Linux distributions, by contrast, deliver free, regular security updates for the supported lifespan of their respective LTS bases, typically five years or more. The trade-off is that users must take responsibility for applying updates and configuring security tools themselves, though mainstream distros make this straightforward.

ReactOS, emphatically, is not a security solution; its alpha code should never face untrusted networks.

Strengths and risks of the open-source path

Strengths:
- Zero licensing cost eliminates the need for a new Windows license or a new PC.
- Extended hardware life reduces e-waste and saves money.
- User autonomy offers control over telemetry, forced accounts, and update policies.
- Desktop flexibility means you can choose an interface that matches your workflow, whether it’s Windows-like, macOS-like, or something entirely bespoke.

Risks:
- Application gaps may persist for certain professional or niche software, requiring VMs or dual-booting.
- Support varies—community forums are excellent, but there is no vendor SLA akin to Microsoft’s commercial support.
- Learning curve still exists; administrative tasks sometimes dip into the command line, though graphical tools now cover most common operations.
- ReactOS instability makes it unsuitable for anything beyond experimentation.

What Ukrainian users should do now

The window between now and October 2025 is the time to experiment. Local tech communities are mobilizing, and resources are plentiful. A practical checklist emerges:

  1. Don’t wait for the deadline. Start testing live USBs on your own hardware today.
  2. Match the distro to your machine.
    - Older, low-spec PCs → Linux Mint XFCE or Zorin OS Lite.
    - Mid-range systems → Zorin OS Core or Linux Mint Cinnamon.
    - Newer, graphics-capable laptops → deepin or Kubuntu.
  3. Plan for Windows apps early. Identify must-have programs and test them under Wine or in a VM well before you commit.
  4. Leverage community events. Repair cafés and installfests can provide the confidence boost and technical know-how that make the difference between a smooth migration and a frustrating false start.

Microsoft’s own telemetry claims that Windows 11 version 24H2 is “the most reliable version of Windows yet,” with unexpected restarts down 24% over Windows 10 22H2. But that statistic, drawn from internal Microsoft data, does nothing for a family in Kyiv whose perfectly good laptop fails the Windows 11 compatibility check. For them, the choice is not between two versions of Windows; it is between an unsupported Windows 10 and a free, actively maintained operating system.

The end of Windows 10 support is a forcing function, not a catastrophe. With a little preparation, Ukrainian users can sidestep the pressure to buy new hardware and instead transform their existing PCs into capable, secure, and modern Linux workstations. The five distributions highlighted here—Zorin OS, Linux Mint, Kubuntu, deepin, and ReactOS—each offer a distinct path forward. The common thread is that none of them demands a credit card, a TPM 2.0 chip, or a processor from an approved list. In an era of tightening budgets and planned obsolescence, that may be the most compelling upgrade of all.
