See the scan results in plain language.
Local results. Read-only scans.
Network tests contact internet services. Scan results remain on your PC; repairs are separate and require consent.
Does scanning change my settings?
No. Scans are read-only. Repairs are separate, require Pro eligibility and explicit consent, and remain subject to safety restrictions.
Will it make my internet faster?
It can find evidence-based improvement opportunities. It does not guarantee a speed increase or repair every router, ISP, hardware or Windows problem.
Is Pro a subscription?
No. Network Doctor Pro is a one-time lifetime Microsoft Store upgrade in the same app.
