Ever wondered how small Windows 11 can get? Meet Nano11

As the countdown to Microsoft’s official discontinuation of Windows 10 approaches, the tech landscape is abuzz with anticipation and speculation. With just two days left until the one-month mark, the deadline for users to transition to Windows 11 looms large. Scheduled for October 14, 2025, this shift is not merely a suggestion but a strategic push by Microsoft, which has been vocal about the advantages of its latest operating system. Bold claims such as “Windows 11 PCs are up to 2.3x faster than Windows 10 PCs” serve as a clarion call for the estimated 400 million users still on the older platform.

However, the transition may not be as straightforward as Microsoft hopes. The stringent minimum system requirements for Windows 11, coupled with certain design flaws, present significant hurdles. It’s important to note that while many of these 400 million PCs may technically support the new OS, the decision to upgrade is ultimately a matter of personal preference.

Exploring Alternatives: Tiny11 and Nano11

In the midst of this transition, alternative solutions are emerging. Earlier this week, Tiny11 received an update to support Windows 11 version 25H2. This update, however, does not introduce new features; instead, it streamlines the experience by removing pre-installed applications such as Clipchamp, Copilot, and the new Outlook client—elements some users consider unnecessary bloatware. Tiny11 is designed specifically for older PCs that struggle to meet the demanding requirements of Windows 11.

Now, a new contender has entered the fray: Nano11. This lightweight version of Windows 11 takes the concept of minimalism even further, reducing the operating system’s footprint to less than 3 GB. According to NTDEV, the developer behind Nano11, “You pretty much can’t get any tinier than this.” By building on the core of Tiny11, Nano11 eliminates even more extraneous components, including Windows Hello packages, unnecessary drivers, and various pre-installed elements.

What sets Nano11 apart is its versatility; it supports any Windows SKU, including Pro, Home, or LTSC. NTDEV notes, “In fact, results are even better with Windows 11 LTSC, and mixed with LZX compression, you can get to complete installations that are 2.8GB in size.” Compared to a standard Windows ISO, Nano11 images are impressively up to 3.5 times smaller.

However, potential users should heed the developer’s caution: “You cannot add back features or languages in an image created with this script! The resulting OS is not serviceable.” This means that once installed, users cannot modify the system to include additional languages, drivers, or features, nor will they receive Windows Updates. Nano11 is intended primarily for testing, development, or embedded use in virtual machines where a minimal, static environment is essential.

While Nano11 may not serve as a daily driver for most, it offers a unique opportunity for those seeking a streamlined experience or a quick testing platform. As the deadline for Windows 10 draws near, the emergence of such alternatives highlights the evolving landscape of operating systems and the diverse needs of users navigating this transition.
