By the point you end organising your new Home windows 11 PC, it is seemingly already sending information to the Microsoft mom ship. Plus, the toggle Microsoft offers you to handle the data circulation does not go so far as you may suppose.
There is a registry edit that I by no means knew existed that enforces a stricter restrict on what your PC sends again to Microsoft, and in contrast to the toggle buried in Settings, it sticks. Enhancing the Permit Telemetry key within the Home windows registry applies a policy-level cap on diagnostic information assortment, and can even grey out the Settings choice totally (so it is working). In the event you pair that with disabling the DiagTrack service, you have bought an efficient privateness setup with out putting in any third-party app. It will not shut down all the info despatched — Microsoft nonetheless collects some baseline information throughout all its Home windows editions, however it positively turns down the hearth hose. Here is how one can do it, and what you may really anticipate.

What Home windows 11 is definitely sending to Microsoft
Required vs. non-compulsory: the 2 tiers of telemetry
Home windows collects information in two tiers. Required diagnostic information is the minimal the corporate says it must maintain Home windows safe and updated, whereas non-compulsory diagnostic information is expanded telemetry that may embody app utilization, website visits for some Microsoft parts, characteristic utilization, and enhanced crash dumps that may additionally include parts of reminiscence. The Settings toggle underneath Privateness & Safety > Diagnostics & suggestions solely offers with the non-compulsory tier. While you toggle this to OFF, your PC will cease sending the richer telemetry, however the required diagnostic information continues to circulation.
On the most elementary Required degree, Home windows collects system data like {hardware} specs, driver variations, and firmware particulars, plus system efficiency information like crash studies, software hangs, and system responsiveness metrics. Microsoft says that a mean PC generates about 6 MB of diagnostic information day by day.
Why the Settings toggle is not sufficient
The registry solely enforces what the UI suggests
The Ship non-compulsory diagnostic information toggle in Settings often is the most seen privateness management, however it’s not enforced at a coverage degree, which suggests it may be overridden or reset. Setting the coverage within the registry enforces the bottom diagnostic information degree allowed by your particular Home windows version, and this registry change successfully turns off and grays out that non-compulsory diagnostic information choice in Settings. Home windows updates have been reported to reset your telemetry settings in Settings (and even DiagTrack), so this registry key repair is a way more sturdy enforcement mechanism. When you handle AllowTelemetry within the registry, the system stops phoning dwelling, although updates nonetheless work. Background reporting drops dramatically.
Doing this repair will solely implement the bottom degree your particular Home windows version helps, which can nonetheless embody some required information. In line with Microsoft, on House and Professional, setting AllowTelemetry=0 might be handled as a 1, which can proceed to permit required diagnostic information like {hardware} configurations, crash studies, and replace data. The one editions this setting will actually be off are Enterprice, Training, and Server variations of Home windows.

The best way to set AllowTelemetry to 0 within the registry
The precise path, key, and worth — with a backup step first
Earlier than you make any modifications, you will need to again up your registry. Open regedit from the Win + R menu and go to File > Export, choose All underneath Export vary, select a save location, and click on Save. That method if something goes flawed, you may restore from this save. Then you may comply with these steps:
- Press Win + R, kind regedit, and hit Enter. Click on Sure on the Person Account Management immediate.
- Navigate to HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsDataCollection
- If the DataCollection key does not exist, right-click Home windows within the left pane, choose New > Key, and identify it DataCollection.
- Proper-click within the empty proper pane, choose New > DWORD (32-bit) Worth, and identify it AllowTelemetry.

- To substantiate it labored, go to Settings > Privateness & safety > Diagnostics & suggestions. The Ship non-compulsory diagnostic information toggle ought to now be grayed out — that is your affirmation the coverage is enforced.
Disabling the DiagTrack service
Going just a little additional
The registry key limits what’s collected, whereas disabling the DiagTrack service stops the transmission mechanism itself. The Related Person Expertise and Telemetry service in Home windows 11 is a background system element that gathers details about how your pc is used, tracks efficiency, app conduct, crash studies, and error logs and sends that information to Microsoft. Here is how one can disable it:
- Hit Win + R, then kind providers.msc
- Scroll to Related Person Experiences and Telemetry
- Proper-click and choose Properties
- Set Startup kind to Disabled > click on Cease > Apply > OK
- Restart
Disabling this service might disrupt troubleshooting workflows, Home windows Replace well being telemetry, or help situations that request richer diagnostic information.
You may’t flip all of it off
Finally, important diagnostic information may nonetheless be despatched after you disable telemetry, and Home windows 11 House customers cannot utterly flip off the gathering of telemetry information, In line with Microsoft, the “Diagnostic information off” setting that makes AllowTelemetry=0 totally efficient is simply obtainable on Home windows Server, Home windows Enterprise, and Home windows Training editions — on House and Professional, the ground is Required diagnostic information, and it’ll keep on.
Even with DiagTrack stopped, crash reporting and crash dumps are managed individually by Home windows Error Reporting, which operates independently of the Related Person Experiences and Telemetry element — that means some diagnostic information can nonetheless go away your system.
What that each one means is you can’t maintain all information from leaving your machine (apart from leaving it disconnected from the web, I suppose), however you may lower the quantity and sort of information Microsoft will get out of your machine.
