Win11Debloat PowerShell Script for Windows 10 & 11: Safety, Defaults, Backups and Reversal

What the command actually does​

The command in the story is:

& ([scriptblock]::Create((irm "[url]https://debloat.raphi.re/[/url]")))

irm is shorthand for Invoke-RestMethod. It fetches content from that address. The rest of the expression turns the result into a script block and runs it. Nothing is "installed" in the traditional sense, but code is still being pulled from the web and executed.

The current Win11Debloat repository explicitly supports Windows 10 as well as Windows 11. The project's own documentation publishes this same quick method. It also warns that the script should be used at your own risk. Another 2026 guide advises reviewing Run.bat, Win11Debloat.ps1 and the configuration and registry files before running a local copy.

The project documents three ways to launch it:

• Quick method: the one-liner above. It is best run from an elevated PowerShell or Terminal window. Per the project's wiki, files land in a temporary Win11Debloat folder and are cleaned up afterward.
• Traditional method: download and extract the ZIP, then double-click Run.bat and accept the UAC prompt.
• Advanced method: extract the ZIP, open an elevated PowerShell window, and temporarily allow script execution for that session only with Set-ExecutionPolicy Unrestricted -Scope Process -Force. Then run .\Win11Debloat.ps1.

If you want to read what you're about to run, the two download-first methods are the more cautious path.

The modes: Default, Custom, App Removal​

After launch, the script presents a menu. The wiki describes these options:

1. Default Mode applies the changes recommended for most users.
2. Custom Mode lets you choose individual tweaks. The project advises reading the options carefully so you don't disable something you want.
3. App Removal Mode shows a list of preinstalled apps to uninstall. Apps the project considers bloatware are preselected.
4. Apply Saved Custom Settings reapplies your last Custom Mode choices.

Custom selections are remembered. With the quick method, the saved files sit in the temporary Win11Debloat folder, so you can reapply a setup later. That is the mechanism behind the writer's claim that you can carry a configuration to another PC.

What Default Mode changes​

According to the project's Default Settings wiki page, the preset covers:

• Disabling telemetry, diagnostic data, activity history, app-launch tracking and targeted ads
• Turning off tips, tricks, suggestions and ads across Windows
• Disabling ads, suggestions and the MSN news feed in Edge
• Removing Bing web search, Bing AI and Cortana from Windows Search
• Disabling and removing Copilot
• Disabling Windows Recall and Click to Do (Windows 11 only)
• Disabling widgets on the taskbar and lock screen
• Showing file extensions for known file types
• Disabling network connectivity during Modern Standby, where supported (Windows 11 only)

The wiki also lists a default app selection. It mixes Microsoft apps with third-party ones. Microsoft entries include Clipchamp, Bing News and Weather, Microsoft News, Office Hub, Teams, Feedback Hub, Quick Assist, Power Automate and Sticky Notes. Third-party entries include Candy Crush, TikTok, Facebook, LinkedIn, Netflix and Spotify. Whether a given app is removed depends on whether it is actually installed on your PC and what you selected.

That caveat matters for the MakeUseOf examples. HP utilities, Lenovo Vantage and similar OEM apps will only vanish if they shipped on your machine and were selected. The writer's own ASUS laptop reportedly had few such apps.

Things the article describes that aren't Default Mode​

The MakeUseOf piece also mentions several extras, none of which the official default list includes:

• Restoring the Windows 10-style context menu
• Hiding the Start menu's recommended section
• Hiding Home, Gallery and OneDrive entries in File Explorer's navigation pane
• Disabling Copilot-related ads in Settings
• Disabling AI features in Edge, Paint and Notepad

The project's parameter list does document most of these as optional switches, so they exist in Custom Mode or as parameters. Treat them as opt-in choices, not something Default Mode does for you. The article's claims about toggling window snapping, Alt+Tab behavior, Windows Sandbox, WSL, Windows Update behavior and Brave settings aren't covered by the project pages reviewed here. Check the current interface before assuming those options exist in your version.

Backups and undo: what is and isn't covered​

This is where the tool is stronger than its reputation, though not without limits.

• Registry backup: The wiki says that starting with release 2026.05.10, Win11Debloat creates a backup of your system registry settings before applying any changes.
• Restoring it: Open the Options menu, choose Restore backup, then Restore Registry Backup. Select your backup file and review the summary. Then restore and restart. Some features, like Widgets and Bing Web Search, also require their apps to be reinstalled from the Microsoft Store.
• Apps are different: The backup does not restore any applications that were uninstalled by the script. You'll reinstall those yourself.
• Re-running to undo: Almost all changes can be reverted by running the script again and unchecking tweaks, with the Detect applied tweaks box checked.
• Restore points: The command-line reference lists a -CreateRestorePoint parameter. It creates one unless a restore point was made in the previous 24 hours. System Restore can remove apps, drivers and updates installed after the restore point. It isn't a backup of your documents.

An independent explainer from iTechGuides makes a similar point. It says no single undo operation reverses every change, and that registry restoration doesn't bring back removed apps. In plain terms: registry backup, restore point and a real file backup each cover different things. Don't treat one as a substitute for the others.

Is it safe? A balanced view​

In its favor: The project is open source and documents its changes. It offers a local-download route and publishes reversal guidance. It also keeps shipping fixes. A WindowsForum report on the 2026.08.24 release described added safeguards around registry backup and restore, and noted that a deprecated parameter was being replaced. That suggests active maintenance, though it also shows that deployment scripts can break when parameters change.

Reasons for caution:

• The quick command runs whatever the remote address serves at that moment. You're trusting the project and its domain every time.
• The MakeUseOf article says the script makes your PC faster and cuts resource use. The project pages don't establish measured boot-time or performance gains. The writer reports saving storage space, which is plausible, but treat speed claims as anecdotal.
• A rival-sounding idea is that disabling telemetry, Copilot or Recall is simply "better." That is a preference, not a universal optimization. Some people use those features.
• Some switches can have real consequences. The article itself warns about BitLocker and Storage Sense. Disabling update or storage-management behavior can bite you later.
• Another independent write-up, from RottenWifi, said it found no universal test matrix of compatibility or performance across Windows 11 25H2 builds and hardware. Broad, unreviewed removal is never risk-free.
• Windows feature updates can reprovision apps or reset settings, so you may need to re-run your preset.
• In managed environments, tools that change policies and registry settings can trigger "managed by your organization" messages. Check with IT policy first on a work device.

A sensible first-boot routine​

1. Finish Windows setup and install updates and drivers first. Confirm the machine works.
2. Back up any files you care about.
3. Download the script from the official project repository, or at least read the quick-launch method's documentation. Verify you're using the official project and domain.
4. Launch it with administrator rights and let it create its backups. Confirm a restore point if you want one.
5. Choose Custom Mode, not Default. Read each option. Skip anything that touches security, encryption, updates or storage unless you understand it.
6. In app removal, deselect anything you use, like Quick Assist, Alarms & Clock or Sticky Notes.
7. Apply a small batch, restart, and check that everything you rely on works.
8. Keep a note of what you removed. The saved settings file helps for reapplying on another PC.

Bottom line​

Win11Debloat is a legitimate, well-documented way to trim a new Windows PC and reclaim some control over ads and suggestions. The MakeUseOf account is a reasonable first-person endorsement. Its "everyone should" framing goes further than the evidence does. The tool saves clicks. It doesn't prove faster performance. The cautious approach is to review before you run, use Custom Mode, and remember that restore tools undo settings far better than they undo deleted apps.
