Windows Debloat Studio

355 options · 15 categories · Windows 11

It tells you exactly what it will do. Then it waits.

A debloating tool for Windows 11 that treats you as the decision-maker. Nothing is selected when it opens, every option explains itself in full, and every change is written down so you can put it back.

Runs offline · No account · No telemetry · Nothing installed

The panel below is the real control, rebuilt in this page with five real options from the catalogue. Operate it. Pick Enable, Disable or Revert, open an explanation, then press Review and apply and see what the app would show you.

Privacy & Telemetry, and four others A demo. Nothing here touches your PC — same as the app, until you confirm.
No changes staged

Enable · Disable · Revert

Three choices, and none of them is the default

The buttons describe the Windows feature, not the tweak — so the same word always points the same way. Every card spells out what each of the three will do to that option, and shows the exact registry values, services, packages or tasks involved.
EnableThe feature is on — usually how Windows ships.
DisableThe feature is off. Not always what you want: a few options are things Windows ships turned off, and those say so.
RevertBack to the exact value it had before this app first touched it. Never a guessed default.
Risk colours were chosen by measurement, not eye: the safe and moderate pair stays distinguishable under red–green colour blindness. Click any screenshot to enlarge.

68 options walked · 0 changed

Rehearse it first. Undo it later.

Tick Dry run and the app walks your entire selection, writing the full log of what it would do — and touches nothing. No registry value, no service, no app, no scheduled task, not even a journal entry. Press play below: this is real output from a real machine.
Dry run
Press Run the dry run to replay a genuine dry run of 68 options, captured on Windows 11 25H2.
When you do apply, the previous state of every single action is recorded first. Undo everything replays that journal backwards, and it survives closing the app — you can undo tomorrow, or after a reboot. Revert on one option uses the oldest record, so it lands on the value your machine had before this app ever ran.

Risk mix across the catalogue

Safe is reversible with no functional loss. Moderate changes a real feature and says which. Aggressive can break updates, security or app installs.

Safe 256 Moderate 79 Aggressive 20

How much of each category was already switched off

Counted only against options whose live state could be read, so nothing is overstated. In the app, clicking a row jumps to that category.

The same figures as above, in the app. Including the honest admission that 136 options could not be determined.

The rest of it

Review, presets, and a stop button

Every apply goes through a review sheet first, with a restore point, a dry run, and a Stop that aborts cleanly between options so the journal never describes a half-finished change.

The review sheet, with the four choices you get before anything runs.
A genuine dry run finishing. No journal file was written, because nothing changed.
Presets stage choices — they never apply on their own, and they are plain text you can read and share.
A free install. A Pro preset keeps its whole description, so you can read what you would be buying.

Pricing

Free for your own PC. Pay when it saves you time.

The free version is not a demo. Every one of the 355 options, every category, and the whole safety net are free forever — because a tool that can change your system but not change it back is not a tool worth having. What costs money is leverage: doing it repeatedly, at scale, or for other people. Pro is for your own machines; Technician is for machines that are not yours. Seven features are paid in total, and the code that enforces them cannot reach the journal, Revert, Undo or the dry run — a test asserts it.

How the licence behaves

Activate once. The app sends your key and a short machine label — PC name plus an eight-character hash — and nothing else. A free install never contacts anything at all. It keeps working offline. Re-checked every 14 days, but an activated PC keeps Pro for 60 days without a successful check, and the panel tells you when the last one was. Only a definite answer — revoked, refunded, expired — downgrades you. Three PCs, movable. Each activation is a named machine. Remove from this PC releases the slot for another one. And the honest part: this app is plain-text PowerShell. The licence check can be edited out by anyone who wants to, and obfuscating a script would only make the code worse. It is a way to pay for the work, not copy protection — and the app's own licence panel says exactly that.

Before you download

What it is, and what it isn't

WindowsDebloatStudio.exe

242 KB · Windows 11 · version 1.0.0

Download

Windows will warn you the first time, and it is right to. The file is not code-signed yet, so SmartScreen shows “Windows protected your PC”. That warning means unrecognised, not unsafe — it is what every new program without a paid certificate gets. Click More info, then Run anyway, if and only if the checksum below matches what you downloaded. Signing is being worked on and is not solved yet: the free route for open-source projects requires an existing public release and would list the signing foundation as the publisher rather than us, so it may not be the right answer here. Saying that beats pretending the warning will not happen.

Verify it in PowerShell before running it:

Get-FileHash .\WindowsDebloatStudio.exe -Algorithm SHA256

SHA-2560dfc4b81bfdf2b9359b1e709018fb2fa90d0abad94ec127fc1ecac0cf0a0c2d9

It is one file, about 242 KB. No installer, no service, no account, no network calls of its own. It unpacks itself into a temporary folder, runs, and deletes that folder when you close it — using the PowerShell and .NET already on Windows 11. The only thing it leaves behind is the journal that makes changes reversible. It is free software, GPL-3.0. The app is PowerShell and XAML — no compiled logic, nothing obfuscated — and the exe is a plain wrapper around those files rather than a packer. Every change it makes is readable before you let it run as administrator, which for a tool like this is the least it should offer. It is not a magic performance tool. Most of what it removes is advertising, telemetry and apps you did not ask for. The honest performance wins are few, and the app says which they are rather than promising percentages. It tells you when it fails. Defender's Tamper Protection silently rejects changes to Defender, and the app says so rather than claiming success. Protected services that refuse to change are logged as access denied, not as done.
Requirements. Windows 11, Windows PowerShell 5.1 and .NET Framework 4.x — all present on a stock install. Administrator rights are needed for machine-wide options; without them the app still runs and says which options will fail. A Windows feature update can reinstate removed apps and reset some policies. Re-stage your preset afterwards. Some things cannot be undone, and each says so on its own card: the disk cleanup options delete data, and a removed app can only be restored locally while its files are still on disk.
