Should you debloat Windows 11? The custom ISO scene is bigger than you think

Windows 11 has been around for long enough to be the standard at this point, but it really gained its major traction and broad adoption after Windows 10's End of Life. Some reasons that might have contributed to a slower uptake include Microsoft's stringent hardware requirements for the operating system and, for some users, its flawed design elements.

Last week, I argued that the Windows 11 customization scene was thriving off of third-party developers because Microsoft seemingly won't give users what they want.

Building on this premise, there has been an influx of tools specifically designed to make Windows 11 feel less "bloated". While it's debatable whether Windows 11 is genuinely bloated, there are a ton of apps and programs preinstalled that might not be useful to the average user.

Our Managing Editor, Richard Devine, recently tinkered with Winhance to improve Windows 11's user experience, ultimately making the operating system feel less bloated. "That Winhance is so user-friendly is what makes it special in my eyes. It's not a tool built for nerds; it's built so anyone can understand it," Devine added.

Debloating Windows 11 remains a hot topic among its users, with some seeking straightforward scripts that can strip the OS down to its bare essentials. A quick look at the r/OptimizedGaming subreddit even shows a desire for custom Windows ISOs to debloat Windows 11 at the point of installation.

After skimming through comments, I noticed that AtlasOS, FoxOS, ReviOS, and GGOS were consistently recommended for the demanding task. I decided to take a look at AtlasOS, which is touted to create a "kinder" Windows experience.

It's essentially selling itself as a lightweight modification of Windows, designed for users looking for "a trusted, performant experience" without necessarily having to sacrifice functionality.

A lightweight Windows mod promises a lot on paper. Telemetry is a major pain point for Windows 11 users, as it collects diagnostic and usage data from your PC and reports to Microsoft. Many feel it's too intrusive, and what's worse, it's difficult to fully disable it.

While Microsoft argues that it improves performance, security, and reliability, some still view it as a data harvesting scheme. However, AtlasOS promises to scrap unnecessary background processes, telemetry, and more.

It also aims to enhance Windows 11's experience by removing Microsoft's unwanted ads and fixing other annoyances, while promoting privacy as a major selling point for the custom ISO.

AtlasOS claims to improve general CPU usage by significantly reducing sudden background spikes and freeing up 1.5 GB of RAM on boot, which can naturally be used for other apps. And finally, it boasts higher average framerates when running PC games like Valorant on Windows 11, expanding its appeal to gamers. Naturally, your mileage may vary.

Debloating Windows 11 can be a gamble

It goes without saying that running unsupported third-party apps could harm your Windows PC since it circumvents critical security measures required to ensure the operating system runs smoothly.

AtlasOS can specifically remove Windows Defender, Restore Points, and System Reset from your system. As such, it's important to exercise caution when interacting with such tools.

It's also worth noting that while AtlasOS gets security patches and cumulative updates, it skips feature updates to preserve optimizations. Additionally, it doesn't provide a rollback or recovery option to stock Windows 11, so you would need to reinstall Windows.

Luckily, Microsoft no longer forces users to install updates when setting up Windows 11, putting an end to the mandatory 30-minute update process forever. This is part of the tech giant's broader plans to address major pain points and improve the general user sentiment around the operating system in 2026.

Microsoft is already making good on its promise by reducing where Copilot and its integrations appear, and bringing back fan-favorite features like the movable and resizable Taskbar. Whether this tempts users away from custom ISOs like AtlasOS remains to be seen.

However, Microsoft isn't pulling the plug on AI entirely either. It recently highlighted its plans to add support for AI agents on the Taskbar and Search Box in Windows 11 next month.

What's your opinion about Windows 11's user experience? Would you use a "debloated" option like AtlasOS?
