How to undo Win11Debloat

#Which method to use

#1. Untick the tweak in the wizard

This is the easiest way, and it does the most. Release 2026.08.24 checks which tweaks are already in effect on your PC and shows them as ticked. Unticking one tells it to undo that tweak.

1. Start Win11Debloat again

   Use the same one-liner or Run.bat as before, and choose Custom Setup. Skip past App Removal without ticking anything.

2. Keep “Detect applied tweaks” on

   It is on by default, at the top of the System Tweaks page. Tweaks that are in effect now are ticked, including ones you applied months ago.

3. Untick what you want back

   For a drop-down setting, such as taskbar alignment or the search box style, pick the option marked (Default) instead.

4. Review and apply

   On the review screen, undone tweaks are listed by their undo name, for example Enable Microsoft Copilot. Click Apply Changes.

Under the hood it imports the tweak's undo file. For two tweaks it does more than that file alone would. Undoing -DisableTelemetry also turns the 8 telemetry scheduled tasks back on, and undoing -DisableStoreSearchSuggestions gives the Store its search database back. It does not reinstall apps that a tweak removed, such as Widgets or the Copilot app.

#2. Restore the registry backup

Before applying tweaks, Win11Debloat saves the current state of every registry key it is about to change. Restoring that backup puts your PC back exactly as it was before that run. That includes settings you had changed yourself, which the undo files cannot know about.

1. Open the ☰ menu

   In Win11Debloat, click ☰ in the top right and choose Restore backup.

2. Choose Restore Registry Backup

   The other option, Restore Start Menu Backup, brings back your pinned Start apps if you cleared or replaced them.

3. Select the backup file

   Backups are named Win11Debloat-RegistryBackup-<date>_<time>.json and live in the Backups folder next to the script. With the one-liner, that is %TEMP%\Win11Debloat\Backups. Win11Debloat lists the changes it will revert before you confirm.

The dialog itself warns to use only backup files made by Win11Debloat, and that removed applications will need to be reinstalled manually.

#3. Import an undo file

76 tweaks come with an undo file in the release's Regfiles\Undo folder, for example Enable_Copilot.reg for -DisableCopilot. Each sets the values back to Windows' default. Every tweak page on this site shows the undo file's exact contents.

1. Get the release files

   If you used the one-liner, the script files were deleted afterwards. Download Source code (zip) from the latest release and extract it.

2. Double-click the undo file

   Open Regfiles\Undo, double-click the file and confirm. Files that change machine-wide settings need an administrator account.

3. Restart Explorer or sign out

   Taskbar, Start and File Explorer changes show after Explorer restarts. Others need a sign-out or a restart.

To do it from PowerShell instead, for example for several tweaks at once:

reg import ".\Regfiles\Undo\Enable_Copilot.reg"
reg import ".\Regfiles\Undo\Enable_AI_Recall.reg"

An undo file only covers the registry. If you undo -DisableTelemetry this way, turn the telemetry tasks back on yourself:

$tasks = 'Application Experience\Microsoft Compatibility Appraiser', 'Application Experience\Microsoft Compatibility Appraiser Exp',
  'Application Experience\ProgramDataUpdater', 'Application Experience\StartupAppTask',
  'Customer Experience Improvement Program\Consolidator', 'Customer Experience Improvement Program\UsbCeip',
  'DiskDiagnostic\Microsoft-Windows-DiskDiagnosticDataCollector', 'Autochk\Proxy'
foreach ($t in $tasks) {
  $path = '\Microsoft\Windows\' + (Split-Path $t) + '\'
  Enable-ScheduledTask -TaskPath $path -TaskName (Split-Path $t -Leaf) -ErrorAction SilentlyContinue
}

Some tweaks have no undo file. The "choose one" settings are undone by picking their (Default) option in the wizard. A few tweaks are PowerShell code rather than registry changes. -DisableStoreSearchSuggestions changes the Store's database: undo it in the wizard. -ClearStart unpins apps: use Restore Start Menu Backup. -DisableWidgets uninstalls the Widgets packages, and Win11Debloat has no undo for it: reinstall Windows Web Experience Pack and Widgets Experience from the Microsoft Store.

How well the undo files work: we tested 74 of them

We applied each tweak on its own on Windows 11 25H2 and then imported its undo file. 50 put every value back exactly as it was. 21 reverted the change but wrote Windows' standard value explicitly where none existed before, which is close but not identical to the original state. 3 left something behind: -HideHome and -HideGallery keep the extra Folder Options entry they add, and -DisableGameBarIntegration keeps its placeholder link handler. Each tweak's result is on its card on the tweak pages. Method and raw data.

#4. System Restore

When the restore point option is on, which it is in Default mode, Win11Debloat creates a restore point called Restore point created by Win11Debloat before changing anything. We saw it created in every Windows 11 test run.

1. Open System Restore

   Press Win + R, type rstrui and press Enter.

2. Pick the Win11Debloat restore point

   Choose Choose a different restore point if needed, select Restore point created by Win11Debloat, and click Scan for affected programs to see what will change.

3. Finish and restart

   Windows restarts to roll back. Anything you installed after that point is removed again.

Use this as a last resort. It also undoes everything else you did since, and it is not designed to bring back Microsoft Store apps.

#Getting removed apps back

Win11Debloat removes apps with Windows' own commands, the same way you would uninstall them. To get one back, install it again. The app list has a checked Microsoft Store link and a winget command for 141 apps, and the app checker shows them for one app at a time.

winget install --id 9WZDNCRFJ3PR --source msstore   # Windows Clock
winget install --id 9MSSGKG348SP --source msstore   # Windows Web Experience Pack (Widgets)
winget install --id 9PC1H9VN18CM --source msstore   # Widgets Experience (Start Experiences App)

• Apps tied to your account, such as To Do and Sticky Notes, get their data back when you sign in again.
• Edge and OneDrive can be reinstalled with winget install Microsoft.Edge and winget install Microsoft.OneDrive.
• The Microsoft Store is the hard one. The simplest fix is an in-place repair: Settings → System → Recovery → Fix problems using Windows Update reinstalls Windows and keeps your files and apps.

#Getting rid of "managed by your organization"

27 tweaks set Group Policy values, which is why Settings says Some settings are managed by your organization after a run. Undoing those tweaks with any method above deletes the policy values, and the message goes away once Settings is reopened. If it stays, sign out and back in. Which tweaks cause it, and how to check.
