Disable the "Telemetry service (DiagTrack)" service

OptionalNeeds administrator rightsReboot needed

"Connected User Experiences and Telemetry". Collects and sends diagnostic data. System name: DiagTrack.

Expected effect

The service will not start and use resources. The effect on performance is small.

Possible side effects

The troubleshooter and some "Diagnostics & feedback" features may work worse.

What exactly changes

Registry key	Value	Type	New value
`HKLM\SYSTEM\CurrentControlSet\Services\DiagTrack`	`Start`	DWord	`4`

How to undo it

Before a change NyxBoost saves the previous values; "Revert" brings them back and removes those that did not exist before.

In NyxBoost: Recovery → “Revert” next to this setting's entry.
Without the program: open the Registry Editor (regedit), go to the key from the table and put back the previous value — NyxBoost records it in its change history.

How NyxBoost checks the result

After applying, NyxBoost reads the values again and compares them with the expected ones. To see the real effect on your PC, use FPS Lab: it measures the same game before and after.
