How to Disable Windows Telemetry and DiagTrack in Windows 10 and 11

Windows sends diagnostic data (telemetry) to Microsoft by default. The DiagTrack service (Connected User Experiences and Telemetry) handles this collection. Here's how to minimize or disable it completely.

What Is Windows Telemetry

Telemetry collects:

Crash reports and error logs
App usage statistics
Device configuration data
Browser activity (if using Edge)

The DiagTrack service (Connected User Experiences and Telemetry) is the main component. Windows calls it "diagnostic data" — it runs automatically and sends data to Microsoft servers like vortex.data.microsoft.com.

Method 1: Settings UI (Simplest)

Win + I → Privacy & Security → Diagnostics & feedback

Diagnostic data: switch from Full to Required only (minimum allowed on Home)
Improve inking & typing: Off
Tailored experiences: Off
View diagnostic data: Off

Method 2: Disable DiagTrack Service

# Stop and disable the telemetry service
Stop-Service DiagTrack -Force
Set-Service DiagTrack -StartupType Disabled

# Verify
Get-Service DiagTrack | Select-Object Name, Status, StartType

Method 3: Group Policy (Pro/Enterprise)

gpedit.msc → Computer Configuration → Administrative Templates → Windows Components → Data Collection and Preview Builds

Allow Diagnostic Data → Enabled → set to 0 - Security (Enterprise only) or 1 - Required
Do not show feedback notifications → Enabled

# Apply via registry (works on Home too)
$path = "HKLM:\SOFTWARE\Policies\Microsoft\Windows\DataCollection"
New-Item -Path $path -Force | Out-Null
Set-ItemProperty -Path $path -Name "AllowTelemetry" -Value 0 -Type DWord

Method 4: Registry (All Editions)

# Minimum telemetry level
Set-ItemProperty "HKLM:\SOFTWARE\Policies\Microsoft\Windows\DataCollection" -Name "AllowTelemetry" -Value 1 -Type DWord -Force

# Disable CEIP
New-Item "HKLM:\SOFTWARE\Policies\Microsoft\SQMClient\Windows" -Force | Out-Null
Set-ItemProperty "HKLM:\SOFTWARE\Policies\Microsoft\SQMClient\Windows" -Name "CEIPEnable" -Value 0 -Type DWord

# Disable feedback
Set-ItemProperty "HKCU:\Software\Microsoft\Siuf\Rules" -Name "NumberOfSIUFInPeriod" -Value 0 -Type DWord -Force

# Disable Delivery Optimization (sharing updates with other PCs)
Set-ItemProperty "HKLM:\SOFTWARE\Policies\Microsoft\Windows\DeliveryOptimization" -Name "DODownloadMode" -Value 0 -Type DWord -Force

# Disable advertising ID
Set-ItemProperty "HKCU:\Software\Microsoft\Windows\CurrentVersion\AdvertisingInfo" -Name "Enabled" -Value 0 -Type DWord

Method 5: Block Telemetry Domains via Hosts File

Add these to C:\Windows\System32\drivers\etc\hosts as Administrator:

0.0.0.0 vortex.data.microsoft.com
0.0.0.0 vortex-win.data.microsoft.com
0.0.0.0 telecommand.telemetry.microsoft.com
0.0.0.0 settings-win.data.microsoft.com
0.0.0.0 watson.telemetry.microsoft.com
0.0.0.0 sqm.telemetry.microsoft.com
0.0.0.0 v10.events.data.microsoft.com
0.0.0.0 v20.events.data.microsoft.com

# Flush DNS after editing hosts
Clear-DnsClientCache
ipconfig /flushdns

Disable Connected User Experiences Completely

# Full script — run as Administrator
Write-Host "Disabling telemetry..." -ForegroundColor Cyan

# Stop and disable DiagTrack
Stop-Service DiagTrack -Force -EA 0
Set-Service DiagTrack -StartupType Disabled

# Disable dmwappushservice
Stop-Service dmwappushservice -Force -EA 0
Set-Service dmwappushservice -StartupType Disabled

# Registry settings
$policies = "HKLM:\SOFTWARE\Policies\Microsoft\Windows\DataCollection"
New-Item $policies -Force | Out-Null
Set-ItemProperty $policies "AllowTelemetry" 1 -Type DWord
Set-ItemProperty $policies "DisableEnterpriseAuthProxy" 1 -Type DWord

# Disable advertising
Set-ItemProperty "HKCU:\Software\Microsoft\Windows\CurrentVersion\AdvertisingInfo" "Enabled" 0 -Type DWord

# Disable activity tracking
Set-ItemProperty "HKLM:\SOFTWARE\Policies\Microsoft\Windows\System" "PublishUserActivities" 0 -Type DWord
Set-ItemProperty "HKLM:\SOFTWARE\Policies\Microsoft\Windows\System" "UploadUserActivities" 0 -Type DWord

Write-Host "Done. Restart for all changes to take effect." -ForegroundColor Green

Verify Telemetry is Reduced

# Check DiagTrack service status
Get-Service DiagTrack | Select-Object Status, StartType

# Check current telemetry level
(Get-ItemProperty "HKLM:\SOFTWARE\Policies\Microsoft\Windows\DataCollection" -EA 0).AllowTelemetry

# Check active connections to Microsoft telemetry servers
Get-NetTCPConnection -State Established |
  Where-Object {(Resolve-DnsName $_.RemoteAddress -EA 0).NameHost -like "*microsoft*"} |
  Select-Object RemoteAddress, @{n='Process';e={(Get-Process -Id $_.OwningProcess -EA 0).Name}}

What You Can't Fully Disable on Home

Windows 10/11 Home always sends some telemetry regardless of settings — level 1 (Required) is the minimum. Full disable (level 0) is only available on Enterprise and Education editions.

For maximum control: Windows LTSC (Long Term Servicing Channel) removes most telemetry components entirely.

Summary

Quickest method: disable DiagTrack service (Stop-Service DiagTrack -Force; Set-Service DiagTrack -StartupType Disabled) + set telemetry policy to 1 via registry. Add hosts file entries to block telemetry domains. On Windows Home, level 0 isn't available — level 1 (Required) is the minimum you can set.
