Windows Update takes so much data usage. I want to stop it. Please tell me how to turn it off permanently.

Short, practical summary and safer alternatives to the replies above.

As notes, Windows Update can chew through limited data. is technically right that the only guaranteed way to never receive updates is to keep the PC offline, but that is rarely practical and leaves the machine exposed to security risks. Microsoft provides only temporary, supported controls (pause, metered, policy-based deferral) rather than a one‑click “permanent off.” Pause updates in Windows.

Two recommended, low‑risk approaches that save data without breaking the system: 1) set your connection to metered so Windows won’t auto-download non‑priority updates, and 2) use the Pause updates control when you need a short window without downloads. Steps are in Settings → Network & Internet (set as metered) and Settings → Windows Update → Pause updates. These are reversible and supported by Microsoft.

For more permanent control on Pro/Education/Enterprise machines, use Group Policy / Windows Update client policies to require manual installs or defer feature/quality updates (feature updates can be deferred up to 365 days; quality up to 30 days). That is the supported method—do not remove or delete Windows Update components or services (the OS has repair services that may re-enable/uproot changes and deleting services can break updates).

Summary: for limited data, prefer metered + manual checks; for organizational control use Group Policy/deferrals; avoid deleting or permanently disabling update services.

If you want, just disable it (through SERVICES) every time you turn on your pc.

sc delete wuauserv in cmd, execute with admin privileges. It will delete Windows Update service.

SC = Service
Delete = Delete
Wuauserv = Windows Update (AU?) Service.

Run the Services Manger (services.msc), then disable the Windows Update service and reboot the machine.

The only way is to block the internet connection.
