Required diagnostic data only

RecommendedNeeds administrator rights

Limits diagnostic data to the "Required" level. This does not turn telemetry off completely: Windows always sends the required level.

Expected effect

Less optional data goes to Microsoft. Updates and protection keep working.

Possible side effects

Group policy: "Settings" may show a note that your organization manages it. The Windows Insider Program requires a higher level.

What exactly changes

Registry key	Value	Type	New value
`HKLM\SOFTWARE\Policies\Microsoft\Windows\DataCollection`	`AllowTelemetry`	DWord	`1`

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.
