See why your PC is slow, not just that it is.
Nexus-DEV-Tool measures what Windows reports, explains it and names the program behind a problem. Free, local, without an account or telemetry.
Why Nexus
Explains, not just shows
Observations, likely causes and unconfirmed guesses stay apart, and the responsible program is named.
No invented values
What Windows cannot measure is shown as Not available. No estimated temperatures, no made-up scores.
Local and private
No telemetry and no account. Nothing leaves your PC unless you use a feature that needs it.
Nothing without consent
Every change is explained, confirmed by you, logged and can be undone where possible.
