Tweaking apps offer a user-friendly option to customize the Windows operating system. Most focus on the removal of apps, disabling certain features, or improving privacy.
While it is possible to apply any tweak manually, it is probably safe to say that the majority of Windows users prefers apps for the job.
TidyOS is an open source tweaker for Windows by Belim, the creator of too-many-apps to count (including ThisIsNot11). It is a well-designed application that is compatible with Windows 11.
Just run the 300 kilobytes app to get started. Windows may throw in a SmartScreen warning, but this is not something to be worried about.

The interface is streamlined. You find the three main groups customizing, debloating, and scripting there. Here is what they do:
- Customizing is the bread and butter group. It includes dozens of tweaks to disable ads, improve privacy, or disable features that you may not need.
- Debloating may be used to remove apps from the system, including many built-in apps that you may not require.
- Scripting gives you advanced options, which are powered by scripts. You can use it to remove AI, create a System Restore point, or remove old Windows versions to free up space.
While the provided tweaks are not as extensive as that of WinAero Tweaker, they do cover major tweaks to deal with annoyance and remove apps or features that are unwanted by part of the userbase.
On the plus side, it is a tad easier to work with thanks to its streamlined interface. Most tweaks are self-explanatory, but you can toggle “feature insights” in the interface to switch to longer descriptions for each tweak that provide additional details.
The changes under customizing take effect immediately, e.g., when you select to remove Copilot or Search from the taskbar, that is done right away.
This is different under debloating and scripting. Here you need to become active, e.g., hit the “remove selected” button under debloating to remove the selected apps from the system.
TidyOS does not require elevation on start, but it may request elevation when you select an action that requires it.
Verdict
TidyOS is a well-designed tweaker for Windows 11 that is not as powerful as some of the others, but you may find easier to use because of that. All in all, it is a good app for users who do not require the massive level of tweaks that other tweakers offer.
Now You: do you use a tweaker for Windows? If so, which is your favorite and why? Feel free to leave a comment down below to join the discussion.
The bad thing about the developer builtbybel is that he develops a convenient and useful tool and after a few months abandons it (stops developing it). Then he creates a new good tool and after a few months stops developing it and abandons it.
Want an example?! Bloatynosy, Bloatboxer (This repository was archived by the owner on Mar 24, 2025. It is now read-only.), SuperMSConfig (This repository was archived by the owner on Mar 17, 2025. It is now read-only.), xd-AntiSpy.
I hope you don’t delete my message.
My opinion is gone, it’s strange that you deleted my opinion and it was informative.

Never have used his tools or any other debloating tool. If users don’t like Windows vanilla versions, then they may want to consider changing versions to something like LTSC or install a distro that’s already modified, like Tiny 11:

A lot of options with ways to tweak if one absolutely wants to reinstall the Windows Store or something else.
VioletMoon, you have published useful articles. I will personally bookmark them. These versions of custom Windows, which are in the links provided by you, may be good, and maybe not, some of them probably do not offer the installation of a language that is generally available in Windows 10/Windows 11 editions.
Many users express the opinion that Windows 11 is unpleasant. It is full of everything, without the ability for the user to remove or not install what he does not want. There are an insane number of running processes that are unnecessary. I will repeat myself, but – many users express the opinion that after Windows 10 the next step is some kind of Linux. For me, Windows 11 is a perversion – Frankenstein, which should be pointed at as something that should not exist in nature. Windows 11 is Sodom and Gomorrah.
Wow, my post appears here almost 24 hours later than I added my comment. This way there can be no quality communication between the users who express their opinions.
