Before changing Projecting to This PC, confirm both devices' Windows versions, Wi-Fi state, Miracast support, network context, and whether Wireless Display is installed. Keep the current state, exact message, and any recent change available so each result can be compared.
2
Choose the supported path
Separate a missing optional feature, unsupported wireless hardware or driver, projection permission, and network discovery before changing firewall or security settings.
3
Check Miracast support
Confirm the sending and receiving devices support wireless display or Miracast.
4
Install Wireless Display
Open Optional features, add Wireless Display, and let Windows finish installing it.
5
Enable projection
Open Settings > System > Projecting to this PC and choose the permitted availability and PIN options.
6
Start the connection
Open the Wireless Display app on the receiver, then use Cast on the sending PC and select it.
7
Verify the result
the sending device discovers the intended PC and completes a private test projection after both devices reconnect. Repeat the original task once more after reopening the relevant app, connection, or Windows session so a temporary result is not mistaken for a fix.
8
Troubleshoot Projecting to This PC
If either device reports no Miracast support, Wireless Display will not install, policy manages projection, or discovery requires weakening the firewall, stop broad resets and return to the last known state. Preserve the exact error, versions, device or account scope, and failed step before using the linked official support channel.
