How a tweak is applied
- You pick it-DisableCopilotA tick box in the wizard, or a switch on the command line. Both end up as the same parameter.
- Win11Debloat looks it upConfig/Features.jsonEach tweak has an entry with its label, the Windows builds it supports, and the
.regfile to apply. - It checks your Windows buildminBuild / maxBuildThe wizard hides tweaks meant for other builds, and Default mode, saved settings and config files skip them. In 2026.08.24, a switch typed on the command line is not checked.
- It imports the registry filereg import Regfiles\Disable_Copilot.regThe same
reg importyou could run yourself. Six tweaks use PowerShell code instead, for example to uninstall the Widgets packages. - It restarts Explorerexplorer.exeSo taskbar, Start and File Explorer changes show up right away. Command-line runs always do this, unless you add
-SkipExplorerRestart. In the wizard it is a tick box, off by default. Some changes still need a sign-out or a restart.

Most tweaks only change settings for your own account. To change them for every account, use What user do you want to apply changes to? on the wizard's first screen, or -User and -Sysprep on the command line. All 89 registry tweaks support -Sysprep, which writes them into the default profile that new accounts are created from.

"Policy" tweaks and the "managed by your organization" message
27 tweaks write to Software\Policies, the part of the registry that Group Policy uses. That is the most reliable way to switch off things like telemetry, Copilot and Recall, because Windows treats a policy as the final word. It also means Windows shows Some settings are managed by your organization on the pages those policies affect, and greys out those switches. Nothing else is managing your PC. Undoing the tweak removes the message. The index above marks these tweaks with a policy tag.
"Choose one" settings
Ten settings in the wizard are drop-downs rather than tick boxes, such as Taskbar search style or Open File Explorer to. Each option is its own switch: -ShowSearchIconTb, -HideSearchTb and so on. To go back, pick another option, including the one marked (Default), which is Windows' own setting.
Undoing a tweak
Each of the 76 tweaks with an undo file has a matching file in Regfiles\Undo\. Double-click it, or run reg import on it, to put the setting back to Windows' default. Win11Debloat also saves a registry backup before each run, which you can restore with Restore backup in its ☰ menu. Our undo guide covers both, plus reinstalling apps.
Questions
Which Win11Debloat tweaks should I use?
Start with the 16 in Default mode: they turn off telemetry, ads, Copilot, Recall, Bing in search and Widgets, and show file extensions. Then add the ones that match what annoys you. The taskbar, Start menu and File Explorer areas are mostly personal preference and easy to reverse.
Can I apply a single tweak without the wizard?
Yes. Pass its switch to the script, for example -DisableBing. Only that tweak is applied, and no apps are removed. Add -Silent to skip the prompts. The command-line guide lists every switch.
Why did a tweak do nothing on my PC?
Usually because it does not apply to your Windows build. The wizard does not offer such tweaks, and Default mode skips them without an error. If you passed the switch yourself, it was applied, but the setting it changes may not exist on your version. Check the Needs column above. Some changes also only show after you sign out or restart.
Are the tweaks the same as in other debloat tools?
Many of them set the same well-known registry values as other tools do, because there is usually one documented way to turn a feature off. The difference is in which ones are selected by default, and that every Win11Debloat tweak comes with a readable .reg file you can check before running anything.
